# Happy Pi Day!

Happy Pi Day, everyone! What is Pi Day, you ask? It’s a celebration of March 14 (3.14) which is equal to pi as we learned it in basic math class. In reality, pi is an irrational number with an infinite number of digits after the decimal point. The most common length to see pi, past the most basic 3.14, is 3.14159265.

What is pi? Well, for those of us who have been out of school longer than we want to think about and those who may not have learned about pi yet, here is a simple explanation from WordNet: (n) pi (the ratio of the circumference to the diameter of a circle; approximately equal to 3.14159265358979323846…). Of course, pi is also the sixteenth letter of the Greek alphabet, but the mathematical meaning of pi is where Pi Day gets its name.

So, how does one celebrate Pi Day? With pie, of course. At the time of writing this post, I haven’t yet decided which kind of pie I’ll be celebrating Pi Day with, but I’ve narrowed the choices down to pumpkin pie or chocolate pie. Believe me, it’s a tough decision.
