March 14 is National Pi Day, the annual holiday that honors pi (π), the mathematical constant that counts 3.14 as its first significant digits.
The special occasion was first commemorated back in 1988, when physicist Larry Shaw organized the holiday in San Francisco to honor the infinite, irrational number that has been utilized in mathematics and science for thousands of years.
