Pi Day is a fun holiday meant to celebrate the mathematical constant of Pi, or π. The event is observed each year on March 14, which is taken from the first three digits of Pi: 3.14.
Pi Day was actually recognized by the U.S. House of Representatives in 2009! Later, in 2019, UNESCO designated Pi Day as the International Day of Mathematics.
