Happy 'Even Day' - the First in 1112 Years
schmofo writes "Today is the first day since Dec. 28, 888 (12-28-888) to have only even digits in its numerical format (02-02-2000). This is quite an event, and complements the last odd day for as long, which occurred back in November." It's also Groundhog day; take a look at Google's logo o' the day. Cute! Update: There is an error above as submitted, which I should have caught: should have been 08/28/888, 12/28/888.
first even reply
Isn't it the first even day since 28-08-888?
12 contains an odd digit
Opps, The last even day would have been 08/28/888.
and I always though 1 was an odd number...
maybe since 8-28-888
I think you will find that zero is neither odd or even. The next even day will be 2nd February 2222 which is not for another 222 years. So from the 19th November 1999 until that date we have a long period where dates are neither odd or even.
Go to a library if you want to see a proof that zero is neither odd or even
Well, technically speaking, your math is worth the first non-negative even whole number. Which is, incidentally, zero. (My Engish might be worth even less.)
I just want to point out, there is an odd digit in 12/28/888. I just couldn't not notice it after the first 186735664 replies.
Free Jon's computers !
celebrate even day with a bowl of hot grits down yours pants. thank you.
An even number y = 2x for some integer x. So certainly, though trivially, x can be 0. Thus 0 is even.
Repeat after me: A NUMBER IS EVEN IFF, WHEN DIVIDED BY TWO, GIVES REMAINDER OF ZERO. ZERO, WHEN DIVIDED BY TWO, GIVES REMAINDER OF ZERO. THEREFORE, ZERO IS EVEN.
He's right 0 is a privative, just like cold. Cold does not exist, it is only our explanation of lack of heat.
Well, technically speaking, the moderator who marked this a insightful is...um...er...well, I can't find the right word. Just forget about it, 'kay? See ya in metamoderation.
Also, for the Odd side of things.. did they forget such numbers at 1-11-1979, 3-13-1957, or even 11-15-1997? Sometimes I wonder how smart the /. community is (not all.. just a few)
Wow! All in the same week. How could ask for anything more.
A sneaky comment: there's a remainder, and it's zero. Z E R O I S E V E N .
Of course it's even. He probably means t4 (see www.elix.com for more) which is nothing - not even even ;-)
You, by yourself, don't seem to know what number is. Infinity is not a number (this is what you proved, sort of). 0 is.
0 is NOT an integer in HIS definition!
And I always feel I am Bill Murray when I read it.
If you look at it that way, then 12 30 1998 would have been the last even day
It is a film with Bill Murray. About a fictious day where everything keeps repeating itself. Kind of like Slashdot, except that its funny.
Groundhog day is just "Murmeltiertag" in German. Watch the movie "Und täglich grüsst das Murmeltier" for more info!
there's a "1" in 16xx and 17xx. Which is odd!
My humble esteem of slashdot has descended an increment, but from a fairly high number. 28-08-888 or 08-28-888?
Get your own website.
Nuff said.
This may mean something to you simple minded creatures that beleive the universe evolves around the base 10 numbering system. This is meaningless for me and other humanoids that proudly use only the binary number system. Good day!
at least on speeling mistake?
(Flame on) You fool. You made TWO spellling mistakes and now I'm going to have to insult you, your country, your family, and use this as my main argument for why you shouldn't be allowed to post ever again, and why you should be shot and ground up to make cheap cattle feed.
Anyway, I think that the general rule is that if you know more about something than someone, you can guarentee that someone will know more about that than you.
While I agree with the whole 08/28/888 deal. Let's look at the logic behind the 12/28/888
2, 4, 6, 8, 10, 12!!, 14
*ahem* okay then.
mzWell let's get nasty then.
Repeat after me ZERO DIVIDED BY TWO DOES NOT GIVE REMAINDER ZERO. ZERO DIVIDED BY ANYTHING GIVES ZERO WITH NO REMAINDER
Obviously your shop is full of programmers that don't know their number theory. I can construct proof's that show zero is odd, and different proof's that show it's even. Hence in conclusion it is neither odd or even
Please think, before you reply, some of you make me so frustrated. Okay, there is a mistake in the text, but if you use that little piece of brain of yours, you know the answer.
(although it's also a bit fun there are so much stupid people out there!)
Groundhog's Day is an important religious holiday that comes early in the spring. It stems back to an event nearly 2000 years ago where hunters in a small Pennsylvania town killed a groundhog and put it in a tomb with they closed off with a giant boulder. Three days later when they came back the boulder had been moved and the groundhog was gone. Ever since then, the scene has been reenacted each year, with the groundhog being ceremoniously dragged out of the tomb. If he does not see his shadow, there will be an early spring. If he does see his shadow there will be six weeks of "Happy Days" dubbed into Russian shown on the USA Network. It is a very cherished event here in the US. It is important to children and old folks alike.
Well, I oversimplified. If you introduce infinity to the number system, you'd better introduce many of them (an infinite number, actually), otherwise your system will not be consistent. Even then it would have some strange properties. So strange I would not risk calling this system "numerical".
Actually, you forget 8-30-888. This whole thing seems pretty pointless. Whoever sent in the story, and whoever posted it should get 30 lashes for stupidity.
Please show me a proof that zero is odd. I want a good laugh.
a movie.. starring Bill Murray
erm..... So 3's even then?
How much ground would a groundhog hog if a
groundhog could hog ground?
Enough ground to hold an even number of
Natalie Portman's - Naked and Petrified.
Oh dear, that would be none - zero.
BECAUSE ZERO IS EVEN.
Sheesh!
Today is the first day since 1-2-2000 (non u.s. date representation)
That was funny!
- Monoid of "natural numbers"
- Ring of "integer numbers"
- Field of "real numbers"
- Field of "complex numbers"
Actually, every monoid (in additive notation) has a special addition-neutral member, which is commonly called "0", and that the alleged number zero is in fact an addition-neutral element in all preceding structures.Have a nice day.
08/28/888 is the last day. Else it would have been 12/30/1998.
Or maybe never, since 1/1/3111 = 00001/00001/0003111.
For those unfamiliar with it here's how it works: A sleeping, nocturnal woodchuck (or marmot) is dragged unwillingly from his warm burrow to be paraded in front of news media and bored spectators. While half awake, camera lights and flashbulbs are flashed in his face.
Tradition has that if he sees his shadow it means winter is almost over, whearas if he doesn't see his shadow it means they either dragged him out of his burrow too early in the morning or he was blinded by the flashbulbs and camera lights.
It's not exactly cruel, but it's not really civilized, either. Like most things in the US.
In Britain every year there's a 1 minute silence at 11:11 on the 11th of November, in memory of the "eleventh hour" surrender of the Germans in World War II...
Waaaaaiit a mo:
If we're doing even dates based on day, month, year, then surely there are a *lot* more:
(dd-mm-yyyy)
02-02-2000
04-02-2000
06-02-2000
...
I appear to be missing something here...
But I own 0 Ferraris, therefore 0 is a quantity
There is no meaning to this date, or that date. It's meaningless. Just like everything else in human existance... completely and absolutely without any kind of objective meaning at all. This date means nothing, just as everything you or anyone else has ever done in their entire lives means nothing. This date, like all your petty "accomplishments", is completely void, meaningless, and worthless.
In the face of individual human death, and thanks to the ultimate end of the universe (in whatever fashion) also being the end of humanity, everything is meaningless. Completely. Void. Nothing.
There, is that ponderous enough for you? Now please excuse us if the rest of us distract ourselves from the utter hopelessness of our existance by getting all worked up over the date today -- if that's okay with you, that is.
Well yeah, the point is that last November 19 was the *last* odd day in something like 1100 years. The next one being after in the year 3111 I think...
since when is 0 an even number? I think you are all a little bit confused with your math here. if your counting the month day and year digit seperately, then 12-30-2000 was the last one. if your counting them as individual digits, then it was in the 9th century AND today is nothing but another day.
Zero divided by zero IS NOT zero... 0/0 is undefined. Zero is an even number. Zero is the class of all classes similar to the empty class.
You're right, In the general case, infinity is not constant. A great deal of quantum mechanical theory rest's on ensureing you're canceling the "same" infinities in the right places. Infinitesimal increments (dx) have similar properties - you always have to be careful you're using the same dx in equations involving differentiation and integration. Sometimes it's perfectly fine to multiply dx(dy/dx), sometimes it isn't.
You don't seem to get it that 0 is by definition a number. The natural numbers are defined inductively as follows:
- 0 is a natural number
- If x is a natural number, then s(x) is a natural number, where s(x) is the successor function that is commonly expressed as s(x) = x +1
- Nothing else is a natural number
In common speech we abbreviate s(0) with '1' and s(s(0)) with '2' and so on.This is stupid. Slow news day?
(5/infinity)/(1,000,000/infinity) = 1
Assuming that infinity is a constant for this, then we would get that 5/1,000,000 = 1.
Wrong. You don't need to assume infinity being constant. (5/inf)/(1*10^6/inf)=5*inf/(1*10^6*inf). Now, infinity/infinity is undefined and thus then the idea collapses with a loud noise and huge clouds of smoke. So there!
Sorry, bud... first even post would be #2...
Now, let's take two real numbers, x and y. Since x and y are real numbers, if we only add, the result must also be a real number. Please give me two values for x and y where x + y = infinity. Oh, you can't. However, it is possible to get x + y = 0 any time that x = y * -1. Therefore, since x and y are real numbers, so is zero. Since 0 mod 2 = 0, it is even.
To sum up. Zero is an even real number (whole integer, too).
Q E fuckin' D
Shall we try that a different way? Ok, let's try the actual definitions of numeric types.
complex numbers - all numbers. zero is included in this subset.
Real numbers - any number without an imaginary portion. zero is included in this subset.
integer - any number without a fractional part. zero is included in this subset.
whole - any non-negative integer. zero is included in this subset.
positive - any whole number greater than zero (yes - its actually defined as being greater than zero!). zero is not a member of this subset because zero = zero.
Hey, I know, how about I prove your theory the correct way?!
5/infinity != 0, and 1,000,000/infinity != 0. However, lets look at lim(x->infintity) (5/x)/(1,000,000/x). Cancel x, we get 5/1,000,000. That's the limit of your "proof". Not only is it flawed logic, but it shouldn't equal 1 to begin with. What you meant to say was this:
lim(x->0) (1/x)/(1/x) = 1, which, as x approaches 0, becomes 1 because the x's cancel out. (1/x)/(1/x) may not defined, but its limit is. Sure, that's not the best proof, but, hey, it was your idea.
Let's use poetry!
Pick up a book on numbers or go back to school. Have a nice day.
0/0 is undefined, not zero. It's closer to one than zero, though. Try a limit though: 1/1=1. 0.1/0.1=1. 0.01/0.01=1. 1e-5/1e-5=1. 1e-10/1e-10=1. 1e-50/1e-50=1. Etc. Anything x/x = 1. The reason its undefined and not one is that any number divided by x approaches infinity as x approaches zero so its kind of a paradox.
-1 is an imaginary number
That's flamebait and you know it. -1 is a negative number, but its not an imaginary number. If Suzy has 3 apples and Bill takes one, how many apples did Bill give Suzy? Well, none, he took them. Mathmatically, we say "took" by using a minus sign. So -1 is not imaginary, especially in when discussing mathematics. Imaginary numbers are divisible by the square root of -1 (but you already knew this - you just wanted to get flamed). sqrt(-1) is imaginary, because there is no physical analogy for that whatsoever.
Today is also odd because it is the 33rd day of the year with 333 days remaining.
Bzzt, please try again. The eleventh millennium would start in 10000 (or 10001 for purists), not the tenth (which would start at 900x). Hopefully we'll have a much more logical calendar by then, and decent education too.
Of course, you know 'millennium' has two 'n's and you were just playing...
You can't approach infinity, either.
Go rent Groundhog Day. A lot of people didn't care for it, but I thought it was pretty funny. That will explain Groundhog Day and should be worth a laugh or two.
Try to remember your math class.
0 (Zero) has no value, therefor it's neither even
nor odd.
Therefor, the first date with only EVEN *digits*
would be 22-22-2222, which doesn't exist.
Who cares about this? Did you know that there won't be a year with 3 digits EVER AGAIN? Did you know that there will never be another year whose digits all add up to 2 for another 9000 years? Do you even care? I sure don't.
.. this has been the funniest thing I've ever seen on /. Congratulations to all involved.
since when is 0 even? zero has NO sign. call me in 2222.
zero IS an even number it's just an agreement in the world of mathematics!!!!
I think we all agree that zero is not odd. So, oddly enough, by process of elimination, zero is even!
Rather a silly thing to do, as there are 20 hundreds, 200 tens, and 2000 ones in "2000".
If 0 is not a number, then how do you count from -5 to 5? A friend of mine tried this and disappeared into a poof of logic.
That settles it for me. Interestingly, even though 0/0 is undefined, 0^0 is equal to 1.
She would have turned 95 today.
Better to celebrate THAT than this even-day nonsense... just my opinion.
-- an Ayn-onymous Coward
The more correct way to explain that 0 is even is from Discrete Mathematics. An even number is defined as a number that is (2 * i), where i is any true integer. 0 is an integer, and 0*2 is 0, so 0 is even. Odds are defined as (2 * i) + 1, which is obvious that it is impossible with zero. Joe Drago
Sure you can: 1..2..3..4..5..6..7..8..9..10..11..12..13.... You can approach infinity all you want, but you can never reach it.
You sir are slow.
Look over the following numbers and tell me what you see
These are examples as you see it
12/28/888
12/30/1998
This is I think more along the lines of what they meant. Which is far less frequent.
8/28/888
11/11/1999
2/2/2000
Maybe next time think before you flame fruitcake.
Just a thought.
hhmmm and next tuesday it is 2-22-2000 yippee I think I'm gona drink till my lungs fall out.
even + even = even odd + odd = even odd + even = odd as 0 + 2 = 2 (even) and 0 + 1 = 1 (odd) I would classify zero as even. and I too think the original poster should be slapped around for not checking his facts (although he certainly made this discussion more lively by not doing so).
12 is an even number to me. So's 10 where that 1 came from.
Backwards. If he sees his shadow (and he did this morning) it means 6 more weeks of winter weather. If he doesn't see his shadow it means an early spring.
I think the largest time_t event of the decade will be in 2004 on January 10th at 07:37:03 UTC and 07:37:04 UTC when 30 true bits all switch to false.
A møøse once bit my sister...
What about 1998? You clown.
In case you haven't notised, 12/28/888 actually contains an odd digit. Come on. Wake up people.
> then 12-30-2000 was the last one Squeeze me? I get confused between past and present sometimes,too.
The last even epoch date:
% date --date '1998/3/3 2:34:48' +%s
888888888
I have come in late to this discussion but I think I can clear things up. Or maybe make them worse. Unknown.
:-)
Aug 28, 888 is the last date with all even digits in it. (ie: 8/28/888) Not Dec 28, 888. (ie: 12/28/888).
This is because the term _digits_ refers to each individual character within the date. Thus,
8-2-8-8-8-8 versus 1-2-2-8-8-8-8
=42 =37
Dec 28, 888 is the last date with even numbers ONLY IF you use the month as a single digit. Some people see the above as:
(Month)-D-D-Y-Y-Y
Which is to say that the month is treated as a single number but the day and year as separate digits. Thus, you'd get:
(12)-2-8-8-8-8
Which is how they get to say Dec 28, 888 was the last fully equal day.
But in these things you have to treat everything the same. Thus, if you want to treat each entry as a single numerical number it would be:
(12)-(28)-(888)
Which then, clearly, would make Feb 2, 890 (02/02/890) the next even numerically numbered date.
Since this is not any kind of a cause for celebration it is clear that 8/28/888 was the true date which should have been posted - and not 12/28/888.
I hope this helps.
1. x = y
2. xy = y^2 ----multiply by y
3. xy -x^2 = y^2 - x^2 ----subtract x^2
4. x(y-x) = (y+x)(y-x) ----factor
5. x = y + x
6. x = x + x ----sub x for y,look at step 1
7. x = 2x
8. 1x = 2x
9. 1 = 2
0 is 0. It is not even. It is not odd. Couple of failed pieces of logic: 1) Just because a numeral is not odd, does not make it even. 0 is its own category. Consider prime numbers -- 0 and 1 are not prime they just exist. The first prime number is 2 and the first nonprime number is 4. By the logic of some in this discussion 0 and 1 would have to be prime (which they are not). 2) You cannot divide 0 by any numeral. 0 is a quantity of nothing and therefore cannot be subdivided (try it on your calculator). 3) All odd and even numbers conform to all rules regarding even and odd numbers, rules of addition, multiplication, and division. 0 does not conform to the rule of division (since it cannot be divided). That fact in and of itself removes 0 as a candidate for either designation.
Why is 2/2/2000 an even day, but not, for example, 2/4/2000? How is 2 even but not 4 or any other even number? And why 2000, not 1996 or 98 or something like that?
one of the things about the date was that it only had 2 even digits in it. 28-8-888 was the last, and 20-2-2000 will be the next.

If you think about it, any date after 1000 made it kind of hard to create all even dates, since the first digit was a one. The same thing's true now. We're not going to have an all odd date until 11/11/3111 (or, if you don't count preceding zeros, 1/1/3111).
Of course, it's all completely irrelevant if you don't go by the Gregorian calendar.
Why does Slashdot have to always assume that the dating method they use is the one that everyone uses? It's like Taco and Hemos and the others are saying, "Well, we use it, and we're Slashdot, so everyone else must use it, too, because we're the Start Page of the universe!" Well, I got news for you, bubbas, there are other dating systems.
There's the Muslim calendar. There's the Jewish calendar. There's the Greek Orthodox calendar. Some guy came up with a calendar where every month got 30 days, except December which got 35. Is it Happy Even Day in these cultures? Oh, no, and they're left out of the fun because of it. Personally, I use the Personal calendar, where the date is 154/22 (the 154th day of my 22nd year). Give it a few more months and I'll be celebrating Happy Even Day, but will Slashdot recognize that?! Oh, no. Because Slashdot's calendar is the only calendar.
I want news, not this editorial garbage. If Slashdot's truly news for nerds, how come we're not celebrating Happy Even Day on the moment when the number of seconds since the epoch has all even digits, huh?
Sheesh.
NOTE: This post not meant for the humor (or humour) impaired.
Isn't this the day that's supposed to keep repeating until you go mad ?
For those who don't "GroundHog Day" was also a movie.
On a more serious note dose anyone want to recalibrate the calendar ? After all it seams to be running 7 years behind of it's proper time and Christ was apparently born in 7BC. This is an unacceptable situation since it would mean we celebrated the 3nd millennium at the wrong time last year and will have an equally incorrect celebration this year.
I say that in 2002 we reset the calendar to 2000 so we can do the millennium thing properly then we recalibrate it to the actual date in the following year ( 2010 ). Of course the calendar finally working properly should also be cause for celebration on a scale unheard of before.
somewhere in there we will restart the count from 0 2000 years in the past so all those who called january, 1 2000 the dawn of a new millennium would become correct.

That 'story' should not have generated 190 comments as of this posting. Who really gives a damn if zero is odd, even, or neither? Who also gives a damn when the next all-odd date is going to occur? You'll all be dead by then. And finally, who gives a damn if the calendar changed between the last all even date.
The bottom line is: Who cares?!
> explain to an ignorant european what Groundhog Day is all about?
Ground Hog is also known as Pork Sausage. Today is the day old time Americans slaughtered the last winter pig and made their last batch of sausage before spring. So all Americans clebrate by having a feast of pork sausages and other kinds of pork. More sausage is consumed on Ground Hog day than on any other single day of the year.
Remember, fellow /.ers, that the only proper way to celebrate Ground Hog Day is with a large meal of pork sausage. All those poor pigs died so that you could have ground hog today, Its the least you can do to honor their passing!
Even at the risk of being moderated as redundant, ;) ;) ;)
It's not 12/28/888, it's 8/28/888
zero isn't even, it's just not odd, so the next day with all evens will have to wait until 2/2/2222 I'm afraid.
...
Although, given the general %02d nature of displaying months, there could be a suggestion that an all-even month number is impossible

"Today is November 19, 1999. The numerical format for today is 11-19-1999. All of the digits are odd. The next Odd day will be 1-1-3111 - which is well over a thousand years away, which we will never see. Days such as 4-13-89 have both even and odd digits, thus, it is neither odd nor even. The next even day will be 2-2-2000 - the first one since 8-28-888. So, now you have a reason to celebrate this Friday as it'll be your last odd day on Earth!!!!!!"

Groundhogs are relatively large rodents that live in holes in the ground.
There is a tradition here (mostly kept alive by people in some little town in PA that get's lots of tourists in today to watch phil the groundhog) that if the groundhog comes of of his hole today and can see his shadow summer is just around the corner, but if he can't we're going to have more winter weather.
I don't think Phil actually gets to come out of the hole of his own accord, I think he gets yanked out on schedule.

If I can't have "none" of something, I can't have a negative number of them either. If this is the reason that "0" is not a number, than -1 is not a number, either.

And if you think even harder, you'll see that it was also hard to have even days in the 18th century. And the 17th, 16th... and so on. The last one was in the 9th century.
PS: It was also difficult to have them in the 20th century.

I asked a question seriously and probably should have made that clear. I was curious why folks would think so. One post was helpful. The rest figured I was complaining. Oh, well...
I had no problem with the "News For Nerds" attribute for this article. I understand number and word play. I just think this particular item doesn't matter a whole lot in the scheme of things.
I also think this communication attempt was not worth the effort (although I accept the blame for not explaining the question); however, I do thank you for your considered response.
Everyone should be aware that:
Tue May 9 06:13:20 1995 (800000000)
was the last, and most recent, all even digit day. The last all odd day was:
Sun Jul 4 17:58:31 1999 (931111111)
The next ones are:
Wed May 18 03:33:20 2033 (2000000000 even)
Mon Feb 21 05:31:51 2000 (951111111 odd)

You cannot divide a number by a concept. You'll see it done, but this is just shorthand for other ideas. It's not what is actually happening.

What the...? I think I saw a penguin...
So, if we were still on the Julian calendar, we wouldn't have an even day for another 13 days, but on the Gregorian calendar it would not be an even day. Is that odd? It definately isn't an odd day...
Likewise, our last Gregorian even day would have occured on the Julian date of 9-13-888, 16 days after their last even day. Which is also odd, but not an odd day. As even they would not have an odd day until well into the next millenium.
Its like opening Christmas presents early. Thanks Pope Gregory.
One is a mathematical concept that represents 'one-ness', does that mean it's not odd?
If 12 is an even number, which it is then, 12/30/1998 was an even day and an even day is not really that unusual is it.
I think we are talking about even digits, and the story is screwed.

...Strictly speaking there's some rule it violates, but I can't remember. I did however argue that I thought it was with my colledge math teachers for months (before I go onto that 1/infinity must be _equal_ to 0 argument). And they kept proving me wrong.
0 is neither an odd nor an even number. It's just 0.

For a discussion about zero (and a different conclusion than yours!), follow this link
Since when is 1 an even digit? 12/28/888 has all even numbers in its numeric representation, but not all even digits. 08/28/888 would have been the last one with all even digits.
Of course, I'm not really that unique. About 1 in every 25 people could say the same.:
Prime months (6): [1],2,3,5,7,11.
Prime days(12): [1],2,3,5,7,11,13,17,19,23,29,31.
Prime years (since 1945) (11): '47, '53, '59, '61, '67, '71, '73, '79, '83, '89, '97.
So there are 792 days in the past 54 years (1946 - 1999) or (54*365 + 13 =) 19723 days -- about 4.01% of them -- when people being born could say the same.
(And for the purists:
Prime years (since 1945) (7): 1949, 1951, 1973, 1987, 1993, 1997, 1999.
Thus, on that basis, 504 / 19723 = 2.56 %, about 1 in 40.)

1) 0 IS a number! There is a huge difference between "nothing" (in math terms the empty set) and a "something" that has a value 0! In other words {0} (the set with 0 as its only element) is very different from the empty set.
2) 0 is an even number: the definition of "even numbers" is the set E subset of Z {u in Z | u = 0 mod 2}. Is 0 Even? YES! 0%2=0!
0 isn't odd or even. It's not a number
Neither odd nor even, this I can grasp.

If you follow his link the the earlier post about 'odd day' back on November 11 1999, sengan, the author of the post says "The next even day will be 2-2-2000 - the first one since 28-8-888."
This comment is completely true -- 28-8-888 is a true 'even day'. However, the last even day according to schmoko is 12-28-888, which is not actually an even day, since it contains a '1' as one of its digits.
I imagine this should clear up most the controversy caused by this big mistake by schmofo...
Since you know code better than math, here's some C to tell if a number is even:
/* by definition */
/* x is TRUE if n is even, FALSE if n is odd */
enum { FALSE, TRUE } x;
int n;
...
x = (n % 2) ? TRUE : FALSE;
Wow, so 0 really is even. Now shut up.

Last time, (Odd Day) a bunch of friends and I got together, (obviously bringing our systems to commune as well) and had a GeekFest(tm, c, and R). We had Dew, Dorritos, and pretzels. Had The Matrix and stayed up all night geekin' around, playing games.
At least, that's what I think we did. It's what I had planned to do, and I am not sure all that happened on that night - but it may have happened in the next couple days.
Who cares about New Years. :) Things like Odd Day and Even Day have much more rarety than even a melennial party opportunity.

Remember that in terms of the date 08/28/888, zero is simply a matter of format, not of content. You remove the issue of zero simply by specifying a different format -- 8/28/888, or from where I come from -- 28/8/888 :)
Does zero actually count as an even digit? I seem to recall being told numerous times that it is neither even nor odd.

True, last 11/19/1999 was the last odd day, but it was also made of two digits, four of each.

2: What debate? 0 is defined to be a number, unless you want to argue that being a member of the reals somehow doesn't qualify it more number status. Infinity is generally not, though IIRC there are exceptions, contexts where the number system is extended to include infinities.

It's been awhile, but, as far as I can remember, zero is a number, it's just not a counting number. It is also the additive identity (i.e. x + 0 = x).
Hm, now I have to go look into this a bit more.
Like I said, it's not a counting number. Thus, I realize, you can't have a literal quantity of 0 of something. I realize that.
I would argue that your definition (and kwsNI's) of "true number" is really the definition of some specific type of number, but unfortunately I'm not at home and can't find anything quickly online, although I'll keep looking. Zero *is* a number.
OK, so, zero is a real number. I wasn't taking into account that it had to represent a quantity, i.e. be a natural/counting number, which it isn't.

I suppose you meant S1G, because an epoch is 2^31 seconds. Yes, the epoch can also mean time 0, but that would make about as much sense as calling the year 2000 problem "the Christ 2000 problem".
BTW, for all you pedants out there, I know that second 1073741824 (2^30) will be more important than second 1000000000, so there's no need to start an argument about what a gigasecond is.

Actually had a chance to be in Punxsutawney a couple of years ago. Got there with a college friend just in time.
Hundreds of drunk or semi-sober people standing in sub-zero temps on a hill next to Gobbler's Knob (cackle,cackle) while the dear rodent,'Phil', gets yanked out from this stump, and is shown to the world like Simba from the pridelands.
Next, when 'Phil' is sufficiently scared out of his wits, two guys in top hats hold up 'Phil' to their ears and unfurl a scroll. The answer is given, and everyone boos or cheers based on the result.
Afterwards, some people leave and other stick around to have their picture taken with the now terrified 'Phil'. Local TV affiliates are there, choppers and planes fly overhead to get a view, and enough local cops are on the scene to comprise a policeman's ball. Cops, you say? Yes, Cops to wrangle the exodus of people from the afore mentioned freezing hill. Not to mention to help clean up the field that has been strewn with garbage, beer cans, beer bottles, empty 40's, and 2 liters filled with (you guessed it) beer. Apparently the majority of masses camp there the previous night and drink heavily.
It's all part of this strange German tradition that (while being fun) strangely deviates from the famous Bill Murry movie. No deja vu was experienced or mentioned by the staggering attendees, nor any wise homespun insights on life aside from remembering never to travel at 3:00AM to a freezing hill for seeing a traditional rodent on display unless you REALLY want to.

I remember back when years ago when the Inet was new and corporate interests played no part in site design and the big sites often changed they're logos and such around holidays. Not just the major holidays but groundhogs day and such too. I even remember some of the big ones playing April fools jokes. Now it seems that things are just a bit colder out there on the Inet. Sure sites toss up a little story about the holiday, but it's just not the same anymore.
I say YAY to Google for keeping a little humanity and fun on the internet. It's not a big deal, but it's nice to see.
For years, especially while Y2K fears were building, I advocated the One True Date Format: YYYY-MM-DD (punctuation is optional and either dots or dashes may be substituted). It sorts correctly. It is locale-independent. It is Y3K-compliant. You need not use it for human interaction, but it should be used to store the dates and transmit them in internal protocols whenever they must be in a printable form. Binary equivalents are acceptable, but may not easily extend to Y10K compliance (see RFC 2550: Y10K and Beyond).
When you use this format, placing the most significant digits first (2000-02-02, see Jargon File 4.2.0: big-endian), it is painfully obvious that there is going to be a 2 in the high-order digit for the rest of our expected lifespan.

if you think about it for a second about this whole thing you realize the 19th century sort of made it hard to create all even dates.

Half right. in '02' the zero tells us that the place holds 2 digits.
in 2000, the 0's are not place holders they are numbers counting the exact quantity of hundreds, tens, and ones of whatever you're counting; in this case years.
Think back to 1st grade.

Given the normal integers with our normal operation of addition zero is the additive identity. i.e. the number you can add to anything to get itself. As a side note in this situation with normal multiplication 1 is the multiplicative identity.
P.S. 0 is both even and a number. What idiot moderated the above statements to the contrary up. Here's a hot tip. If you don't KNOW, please don't moderate the comments.

We should be prepared!
(Is your computer E1G (Epoch 10^9) ready?)
1) Every digit, seperately, must be even. Today does not pass since neither 1 nor 0 are even numbers (even defined in my book as divisible by 2 with no remainder...and zero doesn't count anyway...no sneaky comments about how there's no remainder).
2) Every complete number (day, month, year, etc) must be even. Today passes that restriction, but in that case so did 12-28-1998.
The odd day thing was cute, and true...this is cute, but not true.
So you say that zero is a concept, like infinity. You then attempt to prove this by defining infinity as a constant number.
Fatally flawed logic there, sonny.
Zero is not nothing. Try coding something and switching zero around with NULL/Nothing. It's not going to compile!
My dissection of your fatally flawed logic was your statement that infinity and zero are not numbers, then your use of infinity as a number to prove that zero isn't a number.
I quote:
since I just said that 5/infinity is 0 and 1,000,000/infinity is 0, then: (5/infinity)/(1,000,000/infinity) = 1
Assuming that infinity is a constant for this, then we would get that 5/1,000,000 = 1. Not quite right. That's why 0 is not a number.
So what you're saying is:
Zero is not a number and nor is infinity. But I can only demonstrate that zero is not a number by saying that infinity is a number.
There is the flaw. It may just be badly worded, in which case I apologise.
Oh, and the Null comment was in response to someone else who said zero=nothing. Should have posted it as a separate reply really, sorry.
Doesn't the 1 in the 12 (December) count as an odd number? I thought that was the whole point... It's been a long time since 08/28/888 (With even numbers)
A
No, you don't need infinity to be a number to take limits approaching infinity, because they are formally defined using epsilon-delta theory.
Off the top of my head, if the limit of f(x) as x approaches infinity is L, that is defined as meaning that, for any positive number epsilon, there exists a number delta such that, for any number x that is greater than delta, the equality abs(f(x)-L)
In other words, you can get arbitrarily close to the limit at some value x=delta, and any value of the function at a greater value of x will be closer to the limit than it was at x=delta.
I can do the math to prove that both infinity and zero are not numbers. Unfortunately, HTML (and especially the limited /. HTML set) do not lend me the flexibility to write it nor do I have the time to write it, nor do I really care to, NOR do I think that many people would be able to understand it
Infinity is indeed not a number. However, under the definitions of numbers used by mathematicians worldwide, zero is a number. Of course, if you use your own definition of number, you can easily define it in such a way that zero is not a number. However, I doubt very much that your number system would be useful in the way numbers are normally used.
Also, refusing to support your assertions is a good sign that you're wrong.
You're just arbitrarily defining yourself to be correct. I can just as easily say, 0 is a number: it's the number of hundreds, tens, and ones in "2000".
He wasn't defining integer, he was defining even! Why is it considered recursion to use the same word twice is your definition?
Just to restate his definition: An even number is an integer of the form N=2n, where n is an integer.
So, if 0=2*0, and 0 is an integer, than 0 is even. Whether or not 0 is an integer is an entirely different argument.
The dates 12/14/1774 and 6/22/1462 are all-even-digit numbers if expressed in base 25, 26, 48, 51, 52, 55, 59, 66, 71-73, 78-80, 87, 88, 98, 119-121, 137-146, 163-177, 209-221, 293-295, 355-365, 592-731, or any base greater than or equal to 1775.
I'm not sure why 1642 was "wrong," though, unless you were looking specifically for one of bases 25, 26, 52, 55, 59, 71, 78, 119-121, 137-146, 165-177, 209-221, or 293-295, all of which work with 1462 but not 1642.
I did write a program. However, I only tried to find bases that worked with both dates. So 8 and 16 weren't included, as well as many others that only work with one or the other.

Okay, will this news item be run every other day in every other month this year? 02/04/2000, 02/06/2000, 02/08/2000 etc...
In the spoon, there is no Soviet Russia!
Incidently both 28-08-888 and 02-02-2000 are both Wednesdays..... A topic worthy of discussion on /. ? or who gives a f**k !!
All numbers are mathematical concepts that represent quantities.
How is zero not a number when the rest of them are?
The practice of numbering years from the birth of Christ was started by Dionosius Exiguus, a Syrian monk of the 800's (AD). Given the fact that trade and travel were very limited in those ages, it may still not have been in common usage by 888 AD. It's quite possible that people still used AUC, which counted the number of years since Rome was founded. However, they used the same months and it's quite possible that it was an even numbered year even in that system.
So anyways, back to when the millenium starts. Would the last even day of the tenth millenium be on 8/28/8888? I ask because the tenth millenium would start either on 1/1/10000 or 1/1/10001. The next one would then be on 2/2/20000 wouldn't it? Wow, aren't we lucky! We get 36 or so Happy Even Days this year (and for a while too), but future generations living in 8888 will have to wait 10,000 years for the next one.
Just more random factoids.
Yesterday was 01/02/2000 (on this side of the Atlantic - it was 02/01/2000 on the other side - so no flames, OK?) - an odd digit "1" there. Then it was January - xx/01/2000 - another digit "1". Then it was the previous millennium - xx/xx/1xxx - another "1". Then it was the 900's - xx/xx/9xx - an odd digit "9". Then it was the 890's - xx/xx/89x - another "9". Then xx/xx/889, xx/12/888, xx/11/888, xx/10/888, xx/09/888, 3x/08/888 and 29/08/888
So, yes, 28/08/888 was the last date in which all the digits were even
I noticed that the Google groundhog is not casting a shadow, which should indicate a quick end to this winter. On the other hand, all the Google letters are casting shadows, so without the appropriate amount of caffeine, I am unable to determine the significance of this augury.
Slightly disreputable, albeit gregarious
If you introduce inifnity into your equation, don't you then need to work with limits?
i.e. 5/x = 0 as x -> infinity (which it true)?

Does anybody remember what happened to that Canadain groundhog a year ago? I think it was in Wharton? The creature may of been all white? All I remember is that it died. Please help- I have to do a report on groundhog's day and do not remember.
Real men dump cores! Read my journal, I am neat.

If this is wrong, can you explain to me why 0 isn't even?
Never knock on Death's door:
More race stuff in one place,
than any one place on the net.
Even if the day has to be shared with Phil the evenkeeled rodent,
Even if the 2nd month is an uneven leap year month and is evenly spaced every four years,
Even if the year will eventually end with the dawn of an even millennium,
Even though this is Slashdot and this post has an even number of lines, and even number of words and an even number of letters, it's still Wednesday.
Isn't that odd?

Your right, they each that all the way up through 3rd grade. Then they switch on you and 0 is no longer a number, it's a place holder. Why do you think that Roman numerals have no way of expressing the literal quantity "none". Because you can't have (literal quantity) none of something, we just started doing that to keep track of inventory and the like. Plus like kwsNI said, a true number can be divided by itself and will equal 1. 0/0=1 false, 0/0=0 true, therefore 0 is not a number.

Try here.
BTW, our discussion is using the rule that to be a number zero must represent a quantity (which in dates it does not, it simply holds a place).

You are correct -1 is not a literal quantity. The whole basis of this discussion is: When being represented in a date format e.g.. 02/02/2000 is 0 a number. The answer is no, it is a place holder. It tells us that 02/ is just letting us know that this place accommodates 2 digits 02/ (same thing) 2000 here the 0s are letting us know how far after the decimal to read thus separating 2000 from 200 or 20 or 2. It is not a number, it is simply holding a place.
;)
BTW, -1 is an imaginary number

Ok, watch this:
What is this date? 2/2/2
Now what is this date? 02/02/2000.
All the zeros are doing is telling us how far to carry the decimal to make a legitimate quantity (of which zero is still a place holding number).

I'm surprised you haven't heard of Groundhog Day!!
I suppose it's just another sector of the scientific arena in which Americans lead.
Let me enlighten you. Ages ago, Americans discovered that an immortal groundhog in Pennsylvania named Phil could predict the weather for the next several weeks. Now, this scientific process is very, very complex. I'll attempt to simplify it for you.
1. Phil exits his little abode every Feb. 2 to make his forcast.
2. Phil looks for his shadow. (That's right, his shadow. I told you it was extremely scientific!!)
3. Phil makes his prediction by either running back into his little hole in the ground, or enjoying the day with the film crews and the locals.
Now I wish I could tell you what it meant if he sees his shadow, but, frankly I don't remember. After all, why do we care about the weather when we have our net connection?
Division is generally defined in terms of multiplication; specifically, as the inverse operation to multiplication. So, if you take for granted that
4 * 5 = 20
then *by definition of division* we can say that
20 / 5 = 4
Now, consider the true multiplicative statement
4 * 0 = 0
By definition of division, we can say
0 / 0 = 4
Of course, this doesn't make sense, because we could have used any number in place of 4, which would mean that 0 / 0 can be any number. Mathematicians don't like that, so they say that 0/0 is undefined.
On the same tack, consider
5 / 0 = x
By definition, this would mean
x * 0 = 5
But, of course, any number times zero is zero, so there is no value of x which will make the above statement true. Thus, division by zero is undefined.
There is a ring (math term) term for what zero represents, but unfortunately I don't recall it immediately. Perhaps someone can post it?
3 is an odd digit
called for a boycott of Groundhog Day until the groundhog releases Spring under the GPL.
Sad really.
He means -1 is imaginary in the sense that it is a mathematical abstraction to make it easier to answer questions like what is 1 - 2 ?
You can't have a set of -1 objects, like you can have a set of 1, 2, 3 or even 0 objects.
He does not mean that -1 is a complex number with a real part of 0. Although he was being deliberately confusing.
All I want is a secure system where it's easy to do anything I want. Is that too much to ask ~~ Randall Munroe
As has been pointed out 800 other times here, 0 is most definitely an even number. An even number is by definition a number which can be expressed in the form 2*n, where n is an integer. You can do that with 0.

Well, technically speaking, 0 isn't odd or even. It's not a number. It's a mathmatical concept that represents nothing.

What is groundhog day?
Who cares!!!???
Do not underestimate the power of the Dark side
Man, and I got up thinking today would suck, now I realize how cool it's gonna be! ;)
Today is the first day since December 28, 888 (12-28-888) to have only even digits in its numerical format
Nice try...
On second thought, that depends. Could also be: 12/14/1774 or 6/22/1642, right?
Last prime day: 11/29/1999
Next prime day: 01/01/2003
You showed me how narrow minded I am...
The idea was that the last even-digit days were: :(
12/14/1774 (0xC/0xE/0x6EE)
06/22/1462 (06/026/02666)
both expressed in C convention. I tried binary too, but binary would give 00/00/0000, which is too particular a case to be woth mentioning. I didn't think of any other base.
Year 1642 was a transcription error I made.
It seems you figured out some kind of algorithm to obtain all those bases, but you do not mention 8 or 16! Either I made primary mistake or your algorithm needs a little debugging. Do you agree on bases 8 and 16?
At least in base 1775 one can see it works without any calculation, so congratulations!
Check your e-mail...
I'm dissapointed, so I am giving a slashdot mug to the first person to post a reply to this post, explaining in which circumstances the dates 12/14/1774 and 6/22/1462 are all-even-digit numbers. The year in the original post (1642) is wrong.
I'm serious!
Conditions:
1 - The timestamp will be the criterium.
2 - The answer is posted today.
3 - AC's will not be accepted
4 - I will talk to the winner through his e-mail, as shown in the discussion page, spam-proofing is ok.
5 - Think Geek must be able to ship the mug to the location.
6 - Most important: This message is not moderated down. (And, no, I do not have another account with moderation points)
I really agree that it has to be 8/28/888. Besides, there was another great event like that just a few time ago: 11/19/1999 was the last odd day (odd DIGITS only) until 1/1/3111!!
Regards, Neo XLII [fourty-two]
1 as in 12 isn't an even number, so the last even date must have been 8-28-888.
Will work for bandwidth!
Sort of offtopic, but not too far...
My birthday is October 2, which for all those on the Gregorian calendar is 10-02. When written in the normal person's representation of a date (MM-DD-YYYY), my birthday next year will be on 10-02-2001 which is a palindrome!
In case you were wondering what the last date prior to that to fill such criteria was, I think it was 08-31-1380.

On a more important note, its also the first time ever Slashdot has posted an artical on it being an even date.
