What is Pi Day and why do we celebrate the holiday?
Every March 14, mathematicians, scientists and math lovers around the world celebrate Pi Day, a commemoration of the mathematical sign pi.
The date written numerically as 3/14 match the first three digits of the never-ending number: 3.14
The unique holiday is one that is discussed by math teachers in schools across the country and bakeries and grocery stores often sell pies at a discount that day.
Pi Day was first celebrated in 1988 at San Francisco's Exploratorium, a museum of science and technology that encourages visitors to be hands-on.
The holiday was founded by physicist Larry Shaw, who had been an employee of the museum for more than 15 years.
Pi Day has become an annual tradition at the Exploratorium, and the staff has carried on even after Shaw died in 2017.
"Pi Day is such a special holiday for the Exploratorium," Samuel Sharkland, program developer at the museum, told ABC News. "It started off as a staff gathering and speaks to its magnetism and interest that it's blown up into an international celebration."
He continued, "Sometimes math can be intimidating. But when you have this charismatic number like pi ... there's a lot to explore."
