**Pi Day** is an unofficial holiday commemorating the mathematical constant π (pi). Pi Day is celebrated on March 14 (or 3/14 in *month/day* date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.^{[2]}

**Pi Approximation Day** is held on July 22 (or 22/7 in *day/month* date format), since the fraction ^{22}⁄_{7} is a common approximation of π.^{[3]}
