Pi Day Celebration 2025

Pi or π is the ratio of a circle’s circumference to its diameter. It is an irrational number that is infinite. Often represented by the first three numbers in the sequence, 3.14. That is why March 14 is Pi Day! Whether you like math or understand Pi take a break from studying and come celebrate the infinite possibilities in life by eating pie, playing games, and possibly winning prizes.
