According to one website, as April 31 is purely imaginary, it is i-day!Ben Niehoff said:But there's no April 31. :\ Best you can do is 22/7.
And since e^{i\pi}=-1we can celebrate on the day before! April 30th it is!DrGreg said:According to one website, as April 31 is purely imaginary, it is i-day!
That's what I wrote.nuuskur said:e^{i\pi} = -1 you mean :)

2.7.18 is in three years.
Sextant said: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.
Let's hope the strange month/day/year format has been abandoned then.Sextant said:
EDIT 3/20/15, ERROR CORRECTION: On the last date in the above post, at 159 billion years in the future, incredibly I somehow missed a digit in the original post. How exactly I did that when I copied an pasted the number is beyond me. I must of inadvertently deleted a digit when I put the commas in. In any event the date has been corrected below in bold. It was only 1.433 trillion year error. March 14, 1,592,653,589,793 2:38:46.xxx...
