Pi Day

Pi Day is a celebration of the mathematical constant Pi.



A version of Pi Day is celebrated in the Math Faculty once every term. These are the traditional Pi Day (March 14th - 3/14), Pi Approximation Day (July 22nd - 22/7) and the 314th day of the year (November 9th or 10th depending on if a leap year). These events are hosted by MathSoc. In the past they have included pie-eating contests, pi-recitation contest, pie the dean and much more.

Other faculties also celebrate pi day but to a lesser extent.

History at UW
The earliest known official or large-scale celebration of Pi Day was organized by Larry Shaw in 1988 at the San Francisco Exploratorium.

The earliest reference found for a pi day celebration at Waterloo is Mach 14, 2000, and was sponsored by MathSoc and Nortel.

In 2004, a documentary of the phenomenon of pi day was shot at the University of Waterloo.
