If you don't already know, [pi][1] [day][2] happens on March 14 (3-14) every year. Festivities include reciting digits of pi and eating pies. I understand that it's all in good fun, but I've always felt that pi day is bad PR for mathematics. To non-mathematicians, it gives the impression that mathematics is about voodoo numerology, memorizing (or computing) digits of pi, and bad puns. The bad puns part is pretty accurate, but I don't care for the others.

So I propose we come up with some alternatives to pi day that send a better message about what mathematicians do. If you've got an idea, post it here. If possible, include the following information about your proposed holiday:

- when is it celebrated?
- what are the festivities?
- what kind of food would be associated with this day?

Please post only **one proposed holiday per post**. If you have more than one, please post multiple answers.
