Essential Background

Pi Day is an annual observance celebrated on March 14th (3/14) because 3.14 represents the first three significant digits of the mathematical constant pi (π), which is the ratio of a circle's circumference to its diameter.

The earliest known large-scale celebration was organized in 1988 at the San Francisco Exploratorium.
