Pi Day is an annual celebration of the mathematical constant π (pi), observed on March 14 due to its first three digits (3.14). Founded in 1988 by Larry Shaw at the Exploratorium in San Francisco, celebrations commonly involve eating pie and pi recitation contests. The U.S. House of Representatives recognized Pi Day in 2009, and in 2019, UNESCO designated it as the International Day of Mathematics.
