Pi Day, is a tongue-in-cheek holiday celebrating the mathematical constant [[Pi]] and is observed on March 14. Celebrations often involve eating pie, cookies or some other spherical delicacy. The date comes from the first three digits of pi (3/14) with some people beginning their celebration at 1:59:26 (the following digits 3.1415926). Some creative Elementary and Middle School teachers use March 14 to introduce their students to the concept of Pi.
Pi Approximation day is a similar holiday, celebrated on July 22 (from the approximation 22/7 which comes close to the value for pi - the European dating method is used in this case).
