Sorry, but the "true" math geeks are waiting for March 14, 2015 at 9:26 and 53 seconds AM to celebrate. Until then, we'll keep our differential equations and T-distributions to ourselves.

One of several days, notably march 14th, 3/14, and the 22nd of July, representing a common fractional approximation 22/7. It's somewhat of a pointless holiday, but it's always fun to annoy the hell out of people by being able to recite digits of pi from memory.

(March 14th)

A holiday celebrated by math teachers and geeks everywhere.

March 14th was the chosen day because pi = 3.14.

Since the next three numbers in the sequence are 159, at 1:59, everyone celebrating must say, "Happy Pi Day!"

And please, don't ask how I know.
