What is Pi Day? In 2009, U.S. Congress passed a resolution to recognize March 14 as Pi Day, in an effort to strengthen focus on mathematics and sciences.
Pi Day falls on March 14, or 3/14, an approximation of the ratio of a circle’s circumference to its diameter. Pi is an irrational number, meaning its digits extend infinitely without forming a pattern, though it is often approximated to 3.14159, or simply 3.14.
