Calling all math lovers, engineers, scientists and STEM majors, it’s your day!

To be more specific, it’s National Pi Day 2022, a global observance celebrating the irrational number. “Pi Day” is on March 14 (since the 3/14 resembles the first digits of the number 3:14).

First held in 1988 as a way to draw greater attention to STEM fields, Pi Day has been celebrated every year since, which coincidentally falls on Albert Einstein’s birthday.

When you divide any circle’s circumference by its diameter and the answer is always approximately 3.14 or π, that’s gotta count for something.

In celebration of National Pi Day 2022, here are some of the funniest and wittiest Pi Day shirts you can find on Amazon!
