Happy 00 Leap Day! next one in 400 years!

Actually, the next 00 leap year will be in 100 years, not 400.

25 * 4 = 100.

No it won’t. 2100 is not divisible by 400, but is by 100, and thus isn’t a leap year.

Uh, let’s see here. . . 2000 is a leap year, right? So 2004 would be a leap year. . . then 2008, then 2012. . . eventually 2088, 2092, 2096, 2100. Right? Or am I really missing something?

What you’re missing is that, with the 400 year exceptions, Centuries aren’t leap years.

1900 wasn’t a leap year, 2000 is, 2100, 2200, and 2300 won’t be. 2400 will.

Sorry. My phrasing there sounded a little rude. It wasn’t meant to be.

Yet another possible Y2K problem…

BTW, this is the first 00 leap year since they started the 400-year rule.

MrKnowItAll said:

Actually, there is another Y2K problem that many people don’t know about and it is caused (sort of) by the leap year. Unlike most years there are 54 weeks in 2000. The last year with 54 weeks in it was 1972, well before computer use became wide-spread. Obviously there aren’t 54 full weeks, but there are days in 54 separate calendar weeks this year (one day in the first week of the year, one day in the 54th).

This is expected to cause problems with some software that will only take input in 53 calendar weeks because programmers didn’t consider the possibility of a 54 week year. Who knows . . .

Well, once again I calmly and confidently post the wrong answer.

This is why I stay out of GQ and GD.

um, no, actually - it’s the second.

The Gregorian calendar came into force (at least in territories that followed the papal bull) the day after October 4, 1582, which became October 14, 1582.

Since 1600 is divisible by both 100 and 400, it was a leap year, the first century leap year under the special rule of the Gregorian calendar.

Aside from dropping the 10 days, the next time the Gregorian calendar deviated from the Julian calendar was 1700 - divisible by 100, but not divisible by 400, so not a leap year.

Sylence, if you haven’t got it by now, check out the Archives: Why do we have leap years? for more on the topic than anyone wants to know.
