Pi Day

Pi Day is an annual festivity dedicated to the mathematical constant π (pi), celebrated on March 14th in honor of the first three significant figures of π: 3, 1, and 4. Larry Shaw, a staff member at the San Francisco science museum, the Exploratorium, established Pi Day in 1988. Traditionally, celebrations feature activities like consuming pie and engaging in pi recitation competitions. The United States House of Representatives officially endorsed Pi Day in 2009. Additionally, UNESCO's 40th General Conference designated Pi Day as the International Day of Mathematics in November 2019.
