Are you ready for a mathematical celebration? March 14^{th} is Pi Day! It’s also the birthday of Albert Einstein, born in Ulm, Germany, 1879.

Pi is the irrational number π = 3.1415926535…

The first three digits of pi coincide nicely with the U.S. mm-dd-yy date format of 3/14 for Pi Day.

Everyone everywhere can join the festivities because there really is no equivalent day in the dd-mm-yy date format. We could try the 31^{st} day of the fourth month, 31-4, or the third day of the 14^{th} month, 3-14. But neither of those days exist! April only has thirty days, not thirty-one, and you’re going to be waiting a long time if you want to get to the 14^{th} month of the year.

Pi is the circumference of a circle, divided by its diameter.

Here’s some more basic information about pi, if I’ve *pi*qued your curiosity.
