    We don't get a pi day in the UK :frown:

    Start a movement! I'm calling for it to be a national holiday!

    But there's no April 31. :\ Best you can do is 22/7.

    Awesome!

    Already set! With AM and PM there is twice the chance!

    Since the next digit after the 5 is a 9 won't the proper approximation be 3.1416? So won't the ultimate Pi moment come in 2016? I guess we could celebrate both years, why not :-p

    You know what you have to eat to celebrate, don't you. It better be a round one...

    I'm also in the UK. :(

    And people around here, guess what is the speciality about next day after this day celebration?

    Actually if you consider milliseconds etc between the 53 and 54th second there will be an instantaneous moment in time tomorrow at which we exactly equal pi. Instant pi? No thanks, give me a slice.

    I really have a headache trying to think what is going on with a PI day via what people discus here,

    I'm not flying out of here any time soon. So I will try again and again. Have a nice weekend everyone!

    Your holiday lasts exactly one second :< And now you have to wait another 100 years for another chance :/

    We can celebrate e-day in July (2.7.) and January (27.1.), using the correct date format.
    2.7.18 is in three years.

    According to one website, as April 31 is purely imaginary, it is [itex]i[/itex]-day!

    You celebrate it at midnight between April 30 and May 1 (a public holiday in many countries!)?

    And since [itex]e^{i\pi}=-1[/itex]we can celebrate on the day before! April 30th it is!

    [itex]e^{i\pi} = -1[/itex] you mean :)

    That's what I wrote.

    I think e deserves it.

    Many numbers do stand on its shoulder.

    We hear of yesterday being the ultimate Pi moment but as someone noted above 3/14/15 was 2000 years ago. I would submit that the ultimate Pi moment occurred on:

    March 14, 1592 with Pi moments at 6:53:58.xxx..... AM and PM.

    Note: this is using a standard 12 hour digital watch display format ( _h:mm:ss.xxx...) allowing 1 digit hours from 0 to 9 and two digit for 10 to 12, but insisting on two digit minutes and seconds. With decimal fraction on the seconds, you can take .xxx..., the actual moment out to an accuracy approaching a jiffy if so desired (Planck time of about 5.4 × 10−44 Seconds).

    Another somewhat ultimate Pi day will be:

    March 14, 15926 with Pi minutes at 5:35 AM and PM. The format using dual digit seconds would exceeds 59, ergo the smallest interval is minutes.

    The next year that we can attain the same accuracy level of accuracy (seconds) as 1592 and thus a moment is:

    March 14, 159,265,389,793 2:38:46 AM & PM. Quite a bit into the future.

    We really missed the boat by not being around in 1592. Note I didn't try any BCE dates.

    Now a question for the much smarter than I. Is mathematics a pure science or is it corrupted by our 4 dimensional space-time (if not our human brains)? The essence being here, because Pi is a never ending decimal, will the Pi moment be an infinite string of numbers or will it end at some increment slightly before the jiffy. My understanding (quite limited) is that the jiffy is the shortest time interval in our universe, any thing shorter you are in the quantum foam. I suppose we could have an infinitely short theoretical Pi moment and and a discrete actual physical Pi moment. The philosophical quandary here being, can we actually have a Pi moment or are we limited to something that approaches a Pi moment. 10^-44 is quite a long moment compared to an infinite negative exponent. I doubt I will lose any sleep pondering this tonight.
