National Pi Day

March 14th

National Pi Day is celebrated annually on March 14th (3/14) in honor of the mathematical constant π (pi), which is the ratio of a circle's circumference to its diameter. Pi has been calculated to over one trillion digits and is used in a variety of mathematical calculations, including geometry and trigonometry. The day is celebrated by math enthusiasts, educators, and students who participate in activities such as memorizing the digits of pi, eating pie, and solving mathematical problems. Pi Day is also an opportunity to promote interest in mathematics and increase public awareness of its importance in science, engineering, and technology.

Who created National Pi Day?

National Pi Day was created by physicist Larry Shaw in 1988. Shaw, a scientist at the San Francisco Exploratorium, organized the first Pi Day celebration at the museum with the aim of promoting mathematics and science education. The event was such a success that it has since been celebrated annually and has gained recognition beyond the museum, becoming a widely recognized holiday among mathematicians, educators, and students.
