Not only does it happen twice a year, but it's a holiday that celebrates Math! It happens once on March 14th (3.14 the decimal approximation) and then again on July 22 (22/7 the fractional approximation).

This year is extra special because I'm teaching**PreCalculus **this summer for the first time in over 10 years! I've also organized a **Wikipedia edit-a-thon to celebrate Pi Day** and STEM related topics. We'll have both pizza and fruit pie!
