Named for the Greek letter and mathematical symbol “π”, which represents the ratio of the circumference of a circle to its diameter, Pi Day is celebrated on March 14 every year because 3/14 corresponds to the first three digits of the π constant, 3.14159.
According to Piday.org, Pi has actually been calculated to over one trillion digits beyond its decimal point, so 3/14 (or 3.14) is only the beginning. The Number Pi continues indefinitely, adding to the fun of learning about the number. Because Pi is a constant number, its calculation remains the same for circles of any size.
