March 14, 2024 - Pi Day is celebrated every year on March 14, which in month-day format (3-14) represents the three digits of the value of π. Pi is the mathematical constant of the ratio of any circle's circumference divided by its diameter.
The idea of "Pi Day" originated with physicist Larry Shaw, who organized the first Pi Day celebration at the San Francisco Exploratorium in 1988. Almost exactly twenty-one years later, on March 11, 2009, the U.S. House of Representatives passed a resolution proclaiming March 14 to be National Pi Day. The resolution encourages schools to teach their students about pi and to "engage them about mathematics."
Pi Day can be observed in many ways, one of which is celebrating and enjoying the homophone "pie" and we have some wonderful resources for you to do just that. Check out some of our pie-related materials today.
