March 14, or 3/14, is upon us, and we want everyone to know that isn’t just another day. Aside from being the birthday of one of the greatest physicists of all time, Albert Einstein, people all over the world celebrate it as National Pi Day, in honor of the mathematical constant π.

Pi, or 3.14159, is the ratio of a circle’s circumference to its diameter. It’s comprised of infinite digits and is used every day by professionals from across different disciplines, from engineering to construction.

Founded in 1988, Pi Day has since become an international holiday and is observed in different ways, including enjoying all kinds of pies, like pizza, sweet, and savory pies.

National Pi Day brings a bevy of pi day deals you wouldn’t want to miss. There are several Pi Day discounts and promos that would allow you to indulge on your favorite treats for less.
