Leap Year Woes in Japan

Anyone have a birthday today?
What's even worse is when they combine half-assed knowledge w/ windowing.
So you end up with code like:
If (2-digit-year) mod 4 = 0 AND (2-digit-year) != 0
then it's a leap year
This code works from 1900 to 1999. But fails in 2000. Considering it was written in the 1980's, isn't that remarkably short-sighted? And these aren't historical dates... they're current rundates!
Does it mean something that they are all actors or just the poster doesn't know anybody else?
-- Si hoc legere scis nimium eruditionis habes.
It's a Y2K problem in the sense that the rule goes:
isleap = false;
if(year%4 == 0) {
isleap=true;
year%100 == 0 ? isleap=false;
year%1000 == 0 ? isleap=true;
}
The extent to which the rules are well-known are inversely proportional to their frequency. Hence, the 100 year exception is quite well known, the 1000 year exception is less well known.
I'm guessing the programmers here knew the 100 year exception, and programmed it in, but didn't happen to know about the 1000 year exception, and didn't look anything up. Assumptions, always a bugger, expecially with dates.

NIST agrees with your first link. The issue, as I understand it is that leap seconds replace leap days for finer tweaking.

Do you have a picture of it? That'd be nice.
Why make things harder on yourself? isleap = (!(year % 4) && (year % 100)) || !(year % 400);
You save the time and effort, don't ask the user the year, and the user has to make a minor correction once every four years (roughly). Is choice #2 really that ugly?
I have to make a correction to my watch every other month (almost), and I'm perfectly happy with that arrangement...
Computers are a different story, but I trust my timezone files with that. They even get daylight savings time on and off at the right dates and hours (which my watch doesn't do either).
One other reason the 33 year cycle was more attractive for a Christian calendar is because thats' the traditional lifetime of Jesus.
But, I mentioned teh 24 hour wander of the time fo the equinox. The equinox is used for the calculation of a number of religious holidays - such as easter. With the gregorian clanedar the wander in time is so large that it can't be kept on the one day. But with the Persian calendar, you can keep it on the same day *if* you choose teh correct meridian.
It just happens that this meridian is about 77 degrees west - roughly where washington DC is... but more interestingly - where Britain founded its first colonies. So, the protestant church could have established this new, more accurate, calendar and if there was a suitable settlement at that longitude, claimed that this was the rightful location of the centre of the christian church.
As it happens the first colony was not well equiped to survive (because tehy were in fact a load of astronomers sent to figure out where teh correct longitude was) and disappeared when britain was unable to supply them for a year.
Actually - there's a really trivial way to calculate it.... I just can't remember what it is.
> Again IIRC 1600 was the last leap year at the turn of a century.
Nope. 1700. The 400 rule is a recent addition.
-- Don't Tase me, bro!
> Following that logic, the years 1700...
Except that this rule wasn't adopted in 1700 and 1700 *was* a leap year.

The bug is intentional. Microsoft is copying the behaviour of the date handling in Lotus 1-2-3, which made the original error.

Not exactly. Consider the following two cases:
Since I mentioned the holiday in February, does anyone else feel kinda shortchanged by the fact that from the last week of November to the middle of February there are five legal holidays, but from the second week of July to the end of August there aren't any? (I know I'm drifting dangerously close to offtopic here...).
This is my opinion and my opinion only. Incidentally, IANAL.
MOO;IANAL.
There used to be a picture linked here.
I have noticed that some applications written using Clipper are also having a problem with today's date. The problem appears to be with programs that never got "Y2K fixed" by adding a SET EPOCH command.
Clipper has always handled dates correctly internally and in its data files; the only Y2K issue appears to be in converting a character representation to the internal format. (For example, in the DTOC() function or in a GET.) Apparently, Clipper programs that haven't had SET EPOCH added have still sort of been working this year anyway. If a year 2000 date is generated internally, and you do a GET on that date, it keeps its 2000 year as long as the user doesn't try to edit it. Or at least, it worked until today. Today, we found out (the hard way) that if you have a date of 02/29/2000 (displayed as 02/29/00) and try to get edit it, Clipper thinks it's an invalid date. The solution is to just Y2K-fix your program (using SET EPOCH), as we all should have done a long time ago.

My Birthday was yesterday. Turned 24, which, if you do the math, means I was born on a leap year (76). When I was born, people were saying the same thing, for my Mom to wait till the 29th. Aparently she was like "screw that, this kid is coming out now!" and I was a delevered a few hours before the 29th rolled around.
;)
I always wondered what it would be like to have a birthday on the 29th. Like, when would I celebrate it, Feb 28, or Mar 1? See, this is the kind of thing that screwed me up as a kid.

I personally know of a multimillion-dollar system that was installed in 1998 and doesn't recognize the leap day today. And this was discovered in September of 1999. Major rush job to clean things up, finished a couple weeks ago, but only the "essentials" are totally recognizing it; anything that isn't date-critical will be displaying 3/1/2000 today AND tomorrow.
I was born 12:04 AM March 1, 1980. Tomorrow is my 20th birthday. Had I been born 5 minutes earlier, today would be my 5th birthday, a la Kintanon here

The modern gregorian calendar was introduced by Pope Gregory XIII in 1582. However, it was only adopted by roman catholic countries in 1582, other countries, including Britain and Russia remained on the Julian calendar.
1600 was a leap year in both the gregorian calendar and in the julian calendar, and 1700 was a leap year in only the julian calendar.
Britain (And it's colonies, including America) adopted the Greogrian calendar in 1752, but other countries switched at other times, eg Egypt in 1875, Russia in 1918 and more recently Turkey in 1927.
So depending on where you are, the last '00 leap year could have been in 1600,1700,1800 or 1900.

I'm sure there are many instances before that, but i'm not familiar with them. I'd say that date's have always been a problem in programs, simply because they're so complex, and easy to get wrong.
isleap = false; // --- NOT 1000!
if(year%4 == 0) {
isleap=true;
year%100 == 0 ? isleap=false;

}
Though this won't bite you until 2400...
You could always combine the best of the lunar and solar calendars and switch to the Hebrew calendar. Or switch to the Chinese calendar--they use a lunar/solar system, and bypass all of those wierd exceptions that the Hebrew calendar uses to keep certain Jewish holidays on certain days of the week.
:-)
Of course figuring out when the leap months are is a bit of a pain in the neck--no regular rules like the Gregorian that any idiot (even many programmers) can keep track of.
Or we could scrap the idea of keeping up with seasons and switch to the Islamic calendar. Of course it's a pain in the neck to program--as the start of the month in most Islamic countries is called by some religious dude looking up and seeing the new moon. ("Hey, it looks like the new moon today! I declare today the start of Muharram!")

No picture.. It's a standard gold-filled open-face Hamilton Perpetual bankers watch, 18 size, with four small diamonds set into the gold and silver face later. I can't say for sure when it was made, but it was pawned in NYC in December of 1892. (The pawnbroker engraved the ticket number and date inside the watch.) It is keywound, so it may very well be older. Family hairloom; I'm the fifth generation to carry it.

Having just played extensivly with it, I am happy to say I have just found the first example of the Y3K bug.. Sadly, during the next millennial rollover, the date changes from '2999' to ' 00; The century dial no longer has enough pre-scribed numerals and is blank. There is enough space on the dial to have another 20 or so centuries, so I'll make sure to have it engraved before then.. ;-)

I had it appraised when I had the dial cleaned three years back. While I wasn't told that it was one of their earliest specimins, I was told that my particular model had gone for $14,000 in open auction, and that the guessed value was $6-8K. $6,000 doesn't mean terribly much to me, I'm not materialistic. I was given the watch with the implicit instruction that it be used, as it had been, and I will.

Remember kids! Guns don't kill people - Americans kill people.
I'm glad you mentioned that, because I strongly believe that a number of places have had big Y2K problems, but don't want to report them. I remember calling Intuit just after the New Year, while I was placed on hold, they said
something about experiencing Y2K problems. I didn't see any announcements in the news about Intuit's Y2K problem.
Hope it wasn't anything serious!
So, why the secrecy? Why isn't any one 'fessing up to their Y2K problems? Nobody wants the embarrassment, the shame of knowing they've had these problems exposed to the public.
Well after doing some reading mostly legal problems. When you get a group of people like lawyers together you really start to have a problem quite fast. Suppose that someone depends on Intuit's software in a major way. Now add in the fact that the person is a large company that has very vested interests in said software. That means that Intuit's in the middle of things and needs to act fast. By not telling anyone they are in effect doing what your probably did as kids: break old man Peterson's window just run and hide and dont' fess up.
Slashdot social engineering at it's finest
Depends which country you're talking about. The calendar was the creation of Pope Gregory XIII in 1582, dropping ten days in October. Catholic countries followed immediately, and Protestant countries by 1700. In Europe, it was only England who had a leap year in 1700. Use of the Gregorian calendar in England (and the colonies) was finally specified by an Act of Parliament in 1751. By then, because of the extra leap year, the correction required 11 days. I believe Russia may not have changed until this century.
My info is from here and here.
Well, I found out today that my watch doesn't handle leap years.... I can't even set it to Feb 29th... have to wait till tomorrow to clock it back and make it right...

But I have canned food and a generator, so I'll be okay, right?
From the Yahoo report here:
An agency spokesman said the computer glitch was caused by an old program installed in the system.
It can't have been that old seeing as leap years occur every 4 years IIRC :) Seeing as I don't think that the rules for calculating leap years are particularly complex and probably in any number of libraries this does seem like a particularly shoddy piece of coding.
It's usually the case that most programmers quite rightly leave this kind of thing to the underlying OS/platform. Which is fine until that is broken - check out this bug report at Sun (free login reqd). The vanilla 1.2 JVM for Unix was not able to parse "29 Feb 2000" into a Date object due to a very obscure bug introduced in Java2. There is a fix, but I know that at least a few people/companies got caught out.

Ooh, a sarcasm detector. Oh, that's a real useful invention.
OTOH -- I have to say that to blow off Y2K issues at this point is a mistake. The mystique of the rollover was a bunch of nonsense -- and we all knew it. But that doesn't mean that there are no real problems. I have seen quite a few screwed up perl scripts, for example. And it really seems to me that, had we done nothing, some bad things could have happened.
I'd wait until a few billing cycles are through before I called the problem over.

Computer breakdowns by intercalary day in Japan
The intercalary day on today's Tuesday, 29 February, caused some
surprising computer disturbances in the Hightech country Japan. As
the press agency Reuters announces, in post offices due to
Jahr-2000-Fehlern, which were released by the intercalary day, 1200
cash machines failed. The Japanese weather service has problems with
the entry of local temperatures and precipitation. According to the
report 43 stations distributed over the country transmit false data
since this morning. Already on Monday some 24-Stunden-Vorhersagen
with an error had been printed out: Instead of " 29. " became " 1. "
as end of the validity period indicated. In north Japan the devices
failed for the display of seismic activities with 20 local offices.
Differently than to the change of year however no breakdowns were
announced in the Japanese nuclear power stations (cp/c't)
If you've any interest in calendar manners you'll know that the current 97 leap years in 400 years calendar was introduced by Pope Gregory because the time of the Equinox was slipping away from the date of the equinox - 10 days by the time the calendar was imposed.
The funny thing is - the 97/400 calendar is in fact inferior to the 8/33 year cycle of the Persian calendar, but for 'political reasons it wasn't introduced. The persian cycle has 7 leap years spaced by 4 years, and one spaced by 5.
The reason that the Persian Calendar is better is that the 97/100 cycle lets the dae of the equinox wander by about 56 hours. While the Persian calendar lets it wander by only 24....
Anyway - there's a load of fun political wrangles and a plan by Queen Elisabeth I of Britain to use this better calendar as a secret weapon against the catholic church.... fun fun fun...

bissextile year \bye-SEKS-tuhl-YEAR\ (noun)
: a leap year in the Julian or Gregorian calendar
The year 2000 is a bissextile year, but the year 1900 was
not because leap years can only occur in century years that are
divisible by 400.
When Julius Caesar reformed the calendar in 45 BC, he
stipulated that an extra day be added to February every four
years. But the Romans didn't add the extra day at the end of the
month; they inserted it after the 24th day of the month. They
also reckoned days near the end of a month by counting backwards
from the first of the following month rather than forward from
the beginning of the current one. The day we call February 24 is
six days before March 1, so it was known as the sextus, or "sixth
day." When Caesar's extra day was added, it became a "second
sextus" or bissextus (appending the Latin "bis," meaning
"doubled"). English speakers adopted "bissextile" to refer to
that extra day, even though its placement in the modern calendar
makes that term a misnomer.

My 1892 Hamilton perpetual got the date correct. It even rolled over to '2000' for me on New Years. I believe it will keep the correct date until 2199. Amazing to think that the engineer had the foresight to see that someone would still be using it more than 300 years in the future. Perhaps the FORTRAN and RPG programmers of the 1960's should have taken a clue from the watchmakers of the 1890's.

Correct me if I'm wrong but the leap year rules are as follows, leap years occur when the year is divisible by 4, except when the year is divisible by 100 unless the year is divisible by 1000. I find it ironic that programmers have to implement one but not both exceptions to the basic rule in order to have a problem. Those programmers who just implemented the /4 basic rule can rest until 2100 before having problems.
Firstly, we need a calendar to identify the seasons. In month X it is summer, in month Y it is winter.
Secondly, a year doesn't last X months, it lasts 365 days, six hours and a bit.
Even an earth day doesn't last 24 hours (oh no it don't) it lasts 23 hours 59 minutes and 58 seconds.
Lastly, they had the leap year wrong a long time. When Christmas started falling in summer, European countries 'invented' the leap year and between 1534 and 1538 all countries in Europe scratched one month, i.e. any date November 1536 does not exist in Holland.

I remember watching a number programs displaying the date 29 FEB 1990 to me a decade ago. That wasn't a leap year. Fortunately for the vendor, who responded quite quickly, the dates were stored internally in Julian format and converted for display, so no data was corrupted. The bug was introduced during some maintenance on some old software. I suspect that they were among the first to start Y2K fixes.
This particular problem arose from the fact that far few programmers completely understand the leap year rules, and the code that does the calculations is rarely touched, usually for some reason not directly related to leap year calculations, such as Y2K remediation. It is all wound up in the reasons why software maintenance gets expensive in nearly every case. The specs were either never written down to the level of individual functions, or they are out-of-date. Comments are incomplete or misleading. There's no automated regression tests to give assurance that nothing has been broken.
Why should we care about this? This particular instance was probably due either to Y2K work or a latent bug from some programmer who over-applied the century portion of the leap year rules. Once it gets fixed, this code won't need to be touched for ages. First of all, Y2K was just a single instance of a justification for going through bodies of code making huge numbers of small changes. Porting is another one. And any programmer with a bit of experience can name at least one or two others.
Earlier, I provided a link to the description of the Extreme Programming practice of automated unit tests. Doing that might not have caught these bugs before they got loose. Testing generally only catches the bugs you know to look for, and the tests can be wrong too. But I'm lobbying here to try to overcome the natural resistance many programmers feel toward testing. I know I'd certainly rather be writing code. The reason I've started automating it is because I have no such aversion to building tools to take that dull task away from me. Larry Wall pointed out that laziness is a virtue for programmers. Use it.
The net will not be what we demand, but what we make it. Build it well.
A friend of mine's son was born today! Although his wife went in to labor at 3am yesterday, we encouraged her to hold off for 24 hours to deliver just for the cool birthday.
I don't think she was amused.
SteveIt may be the case that there have been many more Y2K problems occur than have actually been reported. It may well be that organizations have tried to cover up to avoid looking like they were the only ones who didn't prepare for the worst.
It just so happens that the organisation which I work for had at least 20 Y2K related incidents occur in the first week of 2000 but we have all be told to keep quiet (hence I don't give the organisation name) I can say this: we are one of the largest organisations in the UK and we must have done damn well to keep information about these problems away from the trade press.....
Ripping an new rectum in the fabric of spacetime.

It's intersting to note they did have problems with Y2K (according to the BBC), so this shouldn't have been *too* much of a surprise...
