It wasn't until 2009, thanks to the United States House of Representatives, March 14 was officially recognized as Pi Day and several years later, UNESCO declared the day as the International Day of Mathematics.
The first recorded calculations of pi date back thousands of years, with notable work done by Archimedes and later formalized by mathematician Leonhard Euler, who employed the symbol “π” for the first time around 1737. Such historical facts enrich the celebration of Pi Day and provide insights on the mathematical importance of the day.
