Pi Day is celebrated around the world on March 14th (3/14) every year. Pi (which is represented by the Greek letter“π”) is used in mathematics to represent a constant – the ratio of the circumference of a circle to its diameter – which is approximately 3.14159.

Pi Day will be pretty epic this year because when you look at the date 3.14.15, you can see that it matches the first 5 digits of the number (3.1415). Pi Day falls on this upcoming Saturday.
