Happy Pi Day 2025
posted , Updated Happy Pi Day!
It is once again March 14! In the m/d date format, that’s 3/14. But what about international Pi Day? Well if you do d/m, you are out of luck, 31/4 doesn’t work because April has 30 days. Luckily for everyone, the best date format is year-month-day anyway. It’s !
But we’re leaving off the year. Can we get a real Pi Day? doesn’t work, 59 is absolutely not a real month. We can get our first valid month 31 nonillion years from now, on [1], except that months don’t have 88 days. is also not a valid day. In fact, you have to wait until to get a valid Pi Day.
Which is also a Tau Day, coincidentally. See you in 31 duovigintillion years!
But until then, today I am making apple pie and pizza today. Have a nice day y’all.
I just barely did this one from memory, I had to look the others up. ↩︎
