Like the circle itself, pi is a mathematical constant. Possibly because of its ongoing nature, or maybe because it happens to be Albert Einstein’s birthday, people all over the world celebrate the mathematical sign on March 14 — or 3.14 — by eating pie, baking pies, doing pie runs and even working out some algebraic equations. If you’re looking for a reason to celebrate this year (Because, who isn’t?), join the other 55% of Americans who already celebrate Pi Day by participating in common Pi Day festivities.

To celebrate Pi Day properly, it may help to know a bit more about it. Below are a few fun facts about pi:

- Initially, when Archimedes calculated pi, he only did so up to six digits. This was in the third century B.C.
- By the 1400s, mathematicians had calculated pi up to 17 digits. Another 18 digits were added around 1600. This 35-digit number — the “Ludolphine number” — proved useful for creating the perfect circle down to the atomic level.
- In the 1700s, “pi” received its official name.
- In the 18th and 19th centuries, pi was calculated to 200 digits.
- With the help of technology, and after 303 days of computation, pi was discovered to have more than 50 trillion digits.
- Eventually, Pi was dubbed “irrational” and, ultimately, infinite.
