Pi Day is celebrated on March 14 each year to commemorate the irrational number of 3.141592653.
Pi, or π, is defined as the ratio of the circumference of a circle to its diameter. It’s an irrational number, meaning it cannot be written as a simple fraction. The symbol for Pi (π) was first used in 1737 by Swiss mathematician Leonhard Euler.
The first Pi Day was in 1988 at the San Francisco Exploratorium. Physicist Larry Shaw had the idea to celebrate the day by marching around a circle and then eating some pies. They still have the celebration today.
March 14 is also Albert Einstein's birthday. he was born in Germany in 1879.
