A Pi Day shirt is a t-shirt that is specifically designed to celebrate Pi Day, which is observed on March 14th each year. Pi Day is a holiday that honors the mathematical constant pi (π), which is the ratio of a circle's circumference to its diameter. The date, March 14, corresponds to the first three digits of pi (3.14) which is why it is celebrated as Pi Day.
