Pi Day

March 14 is Pi Day

Pi Day is celebrated each year on March 14 because its numerical date matches up with the first three digits of the mathematical constant π, 3.14. Pi is the ratio of a circle’s circumference to its diameter, which means the distance around the edge of any circle is a little more than 3 times the distance across. It is used across science, technology, engineering, math, and, of course, art!
In 2025, Kioxia Corporation and Linus Media Group calculated pi to 300 trillion digits (that's 14 zeros!), setting a new Guinness World Record. How many digits of pi can you recite?
