Introducing a Calendar System For the Information Age

We can't even get people to agree on daylight savings time. This will never happen. Anyone using this probably is going to type an angry reply on their DVORAK keyboard from a location directly in the center of their own little fake reality.
this will be against god's will somehow
I thought this was called the Human Calendar.

Downmodding is the refuge of the weak. Don't downmod, make a better argument!
Might make sense to start the year at Earth's perihelion, and hence reference it to the orbit, and not to the axial tilt.
Perihelion is, coincidentally, also very close to when the current year starts (Jan 4, this year).

What the hell guys, if you're going to try and design something to replaced an entrenched convention, you might as well go whole hog. Oh wait, no, I know... their website isn't in Esperanto because such projects always fail.
This really takes me back to the olden days of the web, when people used simple html-based sites to spread their ideas for an artificial language, or an improvement on the metric system.
Are we going to have to use Swatch Time with this calendar?
All kidding aside, they mention:
(and for those who complain that UTC shouldn't have leap seconds ... I say go and use TAI or GPS, but don't change UTC because you don't want to deal with the complexity)
Build it, and they will come^Hplain.
Standards
I have created 4 simultaneous Worlds with 4 simultaneous days within a single rotation of Earth and have created 4 simultaneous years in a single orbit of the Earth around the Sun and I have created 4 corner stages of 'human metamorphosis'.
There have been various alternative calendars proposed, and some of them have the property that there's a special day in the yearly calendar which doesn't count as part of the regular seven-day-per-week cycle (such as the "month zero" proposed here).
A significant objection is that some religions require that every seventh day be kept as a holy day. If the calendar contains a day which isn't part of the regular week, then there are sometimes more than seven days between one weekly holy day and the next.
It's not a consideration for me personally. However, I'm sure that this feature would lead to significant resistance to the adoption of such a calendar.
This is nothing more than the ancient Lunar Calendar.
They screw everything up.
We already have TAI and GPS (somewhat) to solve these problems.

THANK GOD!!!
Somebody who can take the time to try and invent a new calendar system...and bases it around the UNIX epoch...has WAY to much time on their hands...what next - should we use the Klingon calendar? - LOL!!!
...a month after Linux takes over the desktop/laptop market.
The conversion to this system would make all the Y2K mitigation costs seem like peanuts. Oh yeah, and a beer to go with the peanuts.
It sucked, btw that is why we don't use it anymore.
Companies will be able to pay their employees only on the mid month days and pocket more interest by holding up their last of month paychecks until the next mid month. It will be great for the economy! Everyone in favor say 'I'.
you realize that you were born BEFORE the epoch.

As far as calendars go, this is not a bad effort. I don't think I would personally use it, but I've seen (and created) far, far worse. It is very regular; the rules have few exceptions, and the exceptions are well-defined. There aren't too many decisions in it that stand out as glaringly unjustified or confusing, other than of course by definition, when you create a new calendar, the very decision to do so stands out as glaringly unjustified. :)
Secession is the right of all sentient beings.
As long as the months are named after Jesus and the twelve disciples.
I object to the use the 'midnight' as a way of describing the change from 0.23.59.59TC to 1.23.59.59TC as I happen to live in UTC-7hr time zone. I suggest the term 'roll-hour'.
Also there should be a different delimiter between days and hours, maybe a slash (ie 0/23.59.59TC).
... but I predict that the US will switch to SI units for everyday measurements before this new calendar is adopted. :)
Einstein explained that space-time is relative. Yet there is no shortage of people attempting to standardize them, which is to say make them absolute. The best we can ever do is to convert from somebody else's frame of reference into ours. There is no intrinsic standard, no absolute. Your pet measurement system is no better than mine; but at least the current one goes for a walk every day. Yours just sits there and licks itself.
13 identical months of 28 days each
365 is semiprime and neither of those factors is either 13 or 28.
in addition to a short Month Zero containing only new year's day
Epagomenal days wreak havoc on "monthly" billing cycles (see: Coptic calendar, Mayan calendar, et al.). This is why the Julian and Gregorian bissextile day is explicitly a part of February.
and a single leap year day every four years (with the exception of every 128 years).
The Gregorian calendar design explicitly rejected more precise intercalation cycles in favor of numbers that were easier to remember (i.e. more user friendly). Hell, the quadrennial bissextile cycle introduced by the Julian calendar got screwed up in Augustus Caesar's own lifetime. Never underestimate the need for simplicity.
The beginning of this zero-based numbering calendar, denoted as 0.0.0.0.0.0 TC
We can't even get all programming languages to start their arrays at 0. What makes you think it'll be easier for non-programmers to accept this?
is on the solstice, exactly 10 days before the UNIX Epoch (effectively, December 22nd, 1969 00:00:00 UTC in the Gregorian Calendar).
The solstice is an instant; the date it occurs on depends entirely on your meridian/time zone (e.g. the Chinese calendar explicitly specifies Beijing time). So "exactly ten days" is a meaningless descriptor.
Besides, since you're adopting a quadrennial intercalation cycle, that instant will drift back about six hours every year, further screwing up your "exactness."
Last but not least: the solstice is a fundamentally difficult astronomical phenomena to measure. The instant it occurs is somewhere in the window where the sun's north-south motion is too small to measure. Equinoxes have historically been measured with far greater precision.
It's "terran" inception and unit durations reflect the human biological clock
Then where the heck are your 28-day months coming from? The billions of people who live under a lunar or luni-solar calendar already know that the average synodic month is about 29.5 days, and that's the "month" that affects tides and human fertility cycles.
and align with astronomical cycles and epochs.
Really?
Days, months and years have nothing to do with each other; there is nothing to "align" to.
Its "computational" notation, start date, and algorithm are tailored towards the mathematicians & scientists tasked with calendrical programming and precise time calculation.
Days, months and years aren't SI units, and the one true SI unit of time has jack shit to do with any of them.
We already have a calendar system "For the Information Age": the second counter. Actually, of course, we have a whole series of them, but they differ only in the zero "epoch" second, so translation between them is trivial. The most widely-used such counter is the unix/POSIX time() value, perhaps augmented with a decimal point and a fractional second value.
This "calendar system" has a property that all the others lack: simple arithmetic operations work with it. And once you have the second for some event, there are library routines that can translate it to a human-readable form in any other calendar that you like.
So feel free to invent other interesting calendars; we software types won't be offended. We'll just ask you to be very precise in how you define your calendar, so we can write the routines to produce your calendar from ours. Of course, we'll expect you to pay us for this unnecessary labor, but it only has to be done once for each calendar. And maybe one of your calendars can be the human-readable calendar that supplants the silly Christian calendar, relegating it to use in scheduling your religious holidays.
Just don't ask us to use your calendar (or any other that's not a single number that can be used to any precision) inside our OSs or libraries. The "Information Age" needs a calendar system that works using ordinary real numbers, and aside from the question of when the zero was, we have that already.
(Actually, there's also the slowly-growing problem of different clock speeds caused by relativistic effects, but that's probably a discussion for a much more technical forum than this one. ;-)
Those who do study history are doomed to stand helplessly by while everyone else repeats it.
Why can we not, when time change comes around next, not agree to change one-half hour and stop. Can 30 minutes mean that much to schoolkids, farmers, etc,? One last change of a half hour then done, forever.

People should switch to metric religion. The sabbaths are every ten days, there are ten super-holy days per year (each with one special rite and ten minor cultural flavorings) which are always guaranteed to never also land on a sabbath so you get an extra day off from work, there are ten gods, the tenth son of a tenth son gets a magic power (among a choice of ten possibe powers, and balanced by one of ten disadvantages), each priest gets immunity from prosecution for one of ten different crimes (yes, rape is one of the choices, but they don't all have to choose rape!), the holy book that you're expected to be familiar with is only a hundred pages long and contains ten myths, and the kilochurches (there are no "megachurches") are only allowed to have one thousand members apiece before they're required to fission into hectochurches, so there's plenty of parking and they don't antagonize their surrounding community so much, thereby limiting the amount that you're hated and loathed in residential areas.
As copyright owner of this comment, I authorize everyone to defeat any technological measure which limits access to it.
Since time and space are the same anyway, let's come up with a truly computational measure of time that reflects that couples with distance, not some rehash of our existing calendar that really isn't much different.

It's all seconds, or fractions of a second to your heart's desire, for calculations and deltas.
The rest is human-usable representation, a "pretty print". Making the pretty print be more useful to computers rather than people is less than helpful.

So, the months are 28 days long ... ... try to get that.
How many days is it from 0:00 at 28th of month one till 24:00 1st of month two?
Wow it is not two days? Just because you idiot decided the first day is named ZERO?
There is no 0st element in anything, there is a first, a last and an n'th and if you want your 'thing' may contain zero elements and be empty!

It's a common misconception that the U.S. uses Imperial Units. Sure, we use the same unit names as Imperial, but really, ours are just a bit off, except for liquid measures, which are off by a fairly large amount.
Modern U.S. standard units are also set to be fixed values of the metric system:
1 pound-mass = 0.45359237 kg (exactly)
1 inch (US Standard)= 2.54 cm (exactly)
1 gallon (US liquid) = 231 cubic inches (exactly) = 3.785 L (approx.)
But, compare:
1 gallon (UK "Imperial") = 4.54609 L (exactly)
There's also the quirk that, for land surveys, the older definition of 1 foot = (1200/3937) meter is still used. The difference between the standard foot and the survey foot is at the fifth decimal place, so most of the time, it's an insignificant difference.
From the second paragraph on the landing page: "The terran computational calendar utilizes integers [...] and all it's units use 0 as their initial position."
I'd hate to use a time keeping system designed by someone who doesn't understand the difference between "its" and "it's".
I can recall hearing about this in 2004, so I don't know what is meant by introducing. The report at the time described the inventor (whose name I wish I could remember) who saw himself as a visionary, which he realised he was when he started taking acid. Furthermore as an acid user he discovered paganism which lead to the need for 13 month years for magical reasons.
like theabysmal calendar, the aquarian calendar, the Kluznickian calendar, and a whole host of others.
new calendars require kings, popes, or dictators to impose them, and even then they might add 80 days (Julius Caesar, I'm looking at you), or remove 11 days (King George II).
Maybe Pope Francis (P-Frank to his friends) has something up his sleeve.

I do remember reading a similar proposal in one of Isaac Asimov's non-fiction books.
His proposal included having January 1 start on a Sunday. This meant there were 13 months each with a Friday the 13th. He considered this appropriate, as I recall.
The Ethiopian calendar has 12 months of 30 days plus a thirteenth month of five or six days (leap year every four years).
Their national travel motto is "Thirteen months of sunshine".
They also start their clock at (our) 6am which can be a bit confusing when making appointments to meet people (our 10am is their 4am).
They also missed the Gregorian calendar correction so it's now 2006!
From Wikipedia:
Like the Coptic calendar, the Ethiopic or Ge'ez calendar has twelve months of exactly 30 days each plus five or six pagome days, which comprise a thirteenth month. The Ethiopian months begin on the same days as those of the Coptic calendar, but their names are in Ge'ez. The sixth epagomenal day is added every four years without exception on August 29 of the Julian calendar, six months before the Julian leap day. Thus the first day of the Ethiopian year, 1 Mäskäräm, for years between 1901 and 2099 (inclusive), is usually September 11 (Gregorian). It, however, falls on September 12 in years before the Gregorian leap year.
The current year according to the Ethiopian calendar is 2006, which began on September 11, 2013 AD of the Gregorian calendar.
I don't read your sig. Why are you reading mine?
They screw everything up.
Ignoring leap seconds just pushes the problem to our great-geat grandchilren. By the time that they have to deal with it the problem will be even worse. Far better to fix your program to cope with leap seconds than leave future generations a problem as your legacy. Don't be lazy.
...that no one has even considered how this stacks-up to the Time Cube.
Here I was hoping this was going to be about a calendar system to replace davical + lightning, Outlook or Google Calendar.
Not so, it seems...

What advantage does this offer over traditional Julian Day numbering. where each day is sequentially numbered and their number is divisible by 7 on Mondays? As long as it is necessary to refer to civil or traditional time that can be easily converted.

That's decimal, not metric.
Science is all about firing a drunk pig out of a cannon just to see what happens.
The next calendar system is as boring and irrelevant as the next programming language. Time is defined and measured by the passing of base unit (say a second) which can be counted. A calendar system is a surface on top of that unit. Make your pick but please do not bother others with your *better* new system.
How about we start by making UTC a thing? Seriously last summer there was an online live stream advertised in PST and GMT. This is while the UK was on BST. So, did they mean UK local time (BST) or GMT (which is one hour behind)?

Why not go back to the old 12 months of 30 days then add in 5 or 6 sync-days depending if it is a leap year.
I can see having 4 weeks of 7 days in a month being useful but I don't think this will fly. What would we name the 13th month?
