Eat pie on Pi Day
Happy Pi Day! Find out about Pi Day.
Pi Day and Pi Approximation Day are two holidays held to celebrate the mathematical constant π (pi) (in the mm/dd date notation: 3/14); since 3, 1 and 4 are the first three decimal digits of π. March 14 is also the birthday of Albert Einstein and the two events are sometimes celebrated together.
There are a large variety of ways of celebrating Pi Day and most of them include eating pie and discussing the relevance of π.[1] The first Pi Day celebration was held at the San Francisco Exploratorium in 1988, with staff and public marching around one of its circular spaces, then consuming fruit pies. The museum has since added pizza to its Pi Day menu.[2] The founder of Pi Day was Larry Shaw,[3] a now-retired physicist at the Exploratorium who still helps out with the celebrations.
