If you didn't pay attention to math teachers who tried to explain circular measurements back in your school days, you may not be aware of National Pi Day. March 14 may not have the fame of Halloween or Easter, but it does make it more fun to memorize math facts. Here's a bit about what National Pi Day is and how anyone can celebrate the occasion with special deals.

National Pi Day refers to pi, which is represented by the symbol 𝜋 in mathematics. The explanation for what pi is relates to circular dimensions. According to Piday.org, pi is the ratio of a circle's circumference to its diameter. The shortest numerical version of pi is 3.14, which is how March 14 (3-14) came to be known as National Pi Day.

## Why do people celebrate Pi Day?

Even though it's likely that only a small sliver of the general population cares about the mathematical constant that is pi, plenty of folks enjoy National Pi Day because of the delicious discounts offered up on pies. Pizza chains and actual dessert pie establishments provide National Pi Day deals.

In 1988, Pi Day was first established by the physicist Larry Shaw. The choice of March 14 is based partly on the mathematical constant of pi, which is 3.14 plus an infinite number of other digits. Another aspect that might be purely coincidental is that it's Albert Einstein's birthday (and years later, in 2018, renowned physicist Stephen Hawking died on that date).
