# Pi Day 2018 Facts: History, Funny One-Liners To Celebrate Mathematical Symbol

Wednesday marks the 30th anniversary of Pi Day, a day for celebrating the mathematical constant pi by digging into some fresh-baked pie. Google Doodle celebrated International Pi Day, which also marks the birthday of renowned theoretical physicist Albert Einstein.

Pi Day is celebrated every year March 14 as the first three digits of pi are three, one and four, representing the date. This day was officially recognized by the U.S. House of Representatives in 2009 to help the country "reinforce mathematics and science education for all students in order to better prepare our children for the future and in order to compete in a 21st Century economy."

It is believed earliest known official celebration of Pi Day was organized by American physicist Larry Shaw in 1988 at the San Francisco Exploratorium.
