I celebrate Pi-approximation day on the 22nd of July

3.14 is about 0.00159 less than pi, whereas 22/7 is about 0.00126 greater than pi, making pi approximation day closer to pi than pi day.

This is the research I come here for.

Sure, but by undershooting you can simply wait until the time is 1:59:26.53589793 to celebrate.

Every day is pi-approximation day. It’s just a question of how good the approximation.

The day 1131/12/30 yields 3.1416 repeating.

According to my calculations, the most approximate Pi ISO day expressed literally is 311/9/11 = 3.141414... Of course 311/11/9 also works

132/3/14 = 3.142857142857143. Not bad!

A 355 day lunar calendar would allow for 355/113, which is pretty good.

An apt comment on the horrid US-ian date format. Although the international notation, YYYY-03-14, which is de rigueur for political correctness, would side with the 14th of March.

I like it just because I can use it in filenames and sort by name and I'm guaranteed to get it in chronological order.

Not the 31st of April?

I mean now you mention it that might make more sense, but we're a simple people bound by our traditions.

This genuinely made me happy. May the Fourth be with you! Wait…

That would be February 3rd, no?

I celebrate it on the 31st of April, like normal people.
