# Hungry for math? Then, You Should Celebrate Pi Day

Pi Day is an annual celebration of the mathematical constant π (pi), which is approximately equal to 3.14. Pi Day is observed on March 14th (3/14 in month/day date format), which corresponds to the first three digits of the decimal expansion of pi. Pi Day was first celebrated in 1988 by physicist Larry Shaw at the San Francisco Exploratorium, and it has since become a popular celebration among mathematicians, educators, and enthusiasts around the world.

Pi Day is often marked by activities and events that involve pi and mathematics, such as pi recitation contests, pie-eating contests, math quizzes, and other educational activities. In recent years, Pi Day has also been recognized as a day to promote STEM education (science, technology, engineering, and math) and encourage interest in mathematics among young people.

(And, of course, a big shout-out to talented cartoonists Bill Amend and the whole crew from the *Foxtrot* comic strip who always celebrate the most unusual holidays.)
