March 14 is **Pi Day**. It is the day that people around the world who write the date in the m/dd format celebrate the mathematical constant pi (π) by doing pi related activities and…eating lots of **pie**. The digits in the date, March 14 or 3/14, are the first three digits of π (3.14), pi Day was founded by Physicist Larry Shaw in 1988.
