Happy Pi Day!
Not every mathematical equation gets its own special day. But Pi — the ratio of the circumference of a circle to its diameter, represented as the Greek letter π — is very special.
Each year on March 14 (3/14) mathematical nerds everywhere celebrate Pi Day. The idea of celebrating Pi was organized by Larry Shaw at the San Francisco Exploratorium in 1988. It even has governmental backing: on March 12, 2009, the U.S. House of Representatives passed a non-binding resolution recognizing March 14 as National Pi Day.
