Happy Pi Approximation Day

You probably know that March 14th is Pi Day, but did you know that July 22nd is Pi Approximation day? Because 22/7 is 3.14285, which is pretty close to pi's digits of 3.14159.

On an interesting side note, I used to get my old zip code in Berlin mixed up with the digits of pi. The zip code was 14195, and I always wanted to write it as 14159 because that seemed to flow better. Okay, okay I admit saying that this side note was interesting was a bit of a stretch, but there you go.

According to Wikipedia, some other approximations include 333/106, or 355/133, or my favorite is 103993/33102.

How do you celebrate Pi approximation day? With a cobbler because it's sort of like a pie?
