## National Pi Day 2024

National Pi Day, celebrated annually on March 14th, commemorates the mathematical constant π (pi). It was established in 1988 by Larry Shaw, a staff member at the Exploratorium in San Francisco. The date, 3/14, aligns with the first three significant figures of π: 3, 1, and 4. This day gained recognition when the US House of Representatives voted in favor of it in 2009. Activities such as pie-eating contests and pi-recitation competitions are popular ways to celebrate. Additionally, in November 2019, UNESCO declared Pi Day as the International Day of Mathematics during its 40th General Conference.
