Welcome to our 32nd annual π Day! Help us celebrate this never-ending number (3.14159 . . .) and Einstein's birthday as well. On the afternoon of Thursday, March 14, 2019, visit us for Community Pi Day, participate in π-related activities, and enjoy a piece of pie. 

Founded at the Exploratorium by our own Prince of Pi, physicist Larry Shaw, π Day has become an international holiday, celebrated live and online all around the world.
