In summary, Pi Day is celebrated on March 14 because the date corresponds to the numerical value of pi (3.14). This day was first observed in 1988 and has since become a fun way to recognize the importance of mathematics, specifically geometry, as pi represents the ratio of a circle's circumference to its diameter. Celebrations often include pie-eating, math-related activities, and discussions about the significance of pi in various scientific fields.
