Join us for Pi Day at the Exploratorium on March 14, 2020!
Every year on March 14—Albert Einstein’s birthday—number lovers can raise a piece of pie to Pi (π) Day, a celebration of one of math’s most famous constants: the irrational, never-ending number π, pronounced pi (3.14159 . . .)
Founded in 1988 at the Exploratorium, Pi (π) Day has become an international holiday, celebrated live and online all around the world. The numbers in the date (3/14) match the first three digits of the mathematical constant pi (π).
