April 31!

Pi day. I learn something new every day. I'll have to add that to my custom calendar.

We might have Pi Day at the local museum and I’m volunteering. I’m going to suggest as one of the ideas that we can print out only the first 16,208 digits of Pi to make a gigantic prime number: http://www.primenumbers.net/prptop/p...p?page=45#haut
It would be about 5 pages. Does anybody know of a web site that lists at least 16,208 digits of Pi so that I can do this?

Edit: Thank you. I've found what I'm looking for: http://www.research.att.com/~njas/sequences/a060421.htm

Once again:
Happy Pi day
for today
3/14

The next PI day will be 3/Jan/2041 (3/1/41). Today is not really a PI day.

Hey, why is the forum time out by 1 hour?

3 Jan 4159 = 3/1/4159 (3 Jan 2041 isn't really a Pi Day, is it?)

Stoopid act of U.S. Congress (http://en.wikipedia.org/wiki/Energy_...ht_saving_time).

Indeed, you are correct. So let's stop celebrating PI day until then.

Still doesn't explain the 1 hour difference. Local time should be computed from the system time. System time should not be affected by daylight saving.

No, we just need not to include the year number.

Local time should be computed from the system time.

... via an algorithm that takes into account (perhaps, erroneously) the start and end of DST.

My option for "DST Correction Option:" is "DST corrections always off". So either it completely ignores this setting, or the system time has changed. Perhaps a third option is that I jumped backwards in time 1 hour. But I consider that unlikely since my time travel experiments won't be ready for another few months.

Or it will be March 14, 15,926 at 3/14/15,926. Sorry, you'd have to wait 13,916 years. I believe that with the system that we are using now that the Windows operating system internal clocks will either fail or be redundant after December 31, 9999, kind-of like the discredited Y2K.

March 14th is also Albert Einstein's birthday. I hear it's also the Ides of March, the day that one of the Caesars fell. I thought that before 44 or 45 BC that The Roman Empire had their New Year's Day on about March 14th, but Augustus Caesar adjusted it.

Pi Day started at 0:00:00 UTC and will end at 23:59:59 UTC. I don't know how some of you came up with these weird time values. You always have to over-complicate such simple things...

Nope. Current versions of Windows are good until beyond year 30000.
