Pi Day Google



Pi Day and Pi Approximation Day are two unofficial holidays held to celebrate the mathematical constant π (pi) (in the month/day format: 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 Marina Koutsis and the three events are sometimes celebrated together.
