Pi Day occurs on March 14, because the date is written as 3/14 in the United States. If you’re a serious math geek, celebrate the day exactly at 1:59 a.m. or p.m. so you can reach the first six numbers of pi, 3.14159.

March 14 is also Albert Einstein’s birthday.

## Who invented pi?

The mathematical concept of pi has been around for thousands of years, but it started to be known by the Greek letter only in the 1700s. Philologist William Jones began using the symbol in 1706, but it was popularized by mathematician Leonhard Euler.

## Why is pi important?

Unless you’re a mathematician or scientist, you probably don’t encounter pi very often. But pi is essential for calculations in math, engineering, construction, physics and space exploration.

## Does pi ever end?

Like our love for pie, pi is infinite. Its exact value can never be calculated, and it doesn’t seem to have a pattern.
