The History

Pi Day is a day to celebrate the mathematical constant Pi (π), used in geometry, number theory and calculus. Pi is the name given to the ratio of the circumference of a circle to its diameter, approximately 3.14159. The earliest known celebrations of Pi Day occurred in 1988 at San Francisco’s Exploratorium, where the public and staff walked around in a circular path, while eating fruit pies. The museum continues to celebrate the day each year, and in 2009, the US Congress officially designated March 14th as National Pi Day.
