Since the most epic Pi Day can be honored just once a century, in the year ending in '15, festivities across the country this Saturday are bound to be special, at least compared to March 14 bashes in other years. From pie-eating contests to 3.14-mile runs, there may well be an infinite number of ways to celebrate this special day in 2015.

Pi is the ratio of a circle’s circumference to its diameter: 3.14159… It literally goes on infinitely. Because of the way dates are written numerically in the United States (by month, day and the last two digits of the year), March 14, 2015, is cause for a stand-out celebration. So even if math wasn't your best subject in high school, you might as well take advantage of the epic Pi Day events, specials and celebrations around the country.

In New York City, Brooklyn bakery Four & Twenty Blackbirds will offer three slices of pie for $14 on Saturday. Pizza parlors will have similar specials, like $3.14 pies at Blaze Pizza Saturday, or Pi-Pizza’s rewards offerings for the whole month of March. Looking for something non-food-based, or interested in something more intellectual? Huge, the Brooklyn-based digital agency, is hosting a Pi Day Hackathon for coders as well as a contest to see who can recite the most digits of Pi.

In Washington, D.C., a lot of bakeries are offering specials on house or homemade pies, by the slice or in full – and some will even come decorated with the Pi symbol. Several pizza houses will also have Pi Day specials ($3.14 is a popular price) and happy hours for pie, beers and more can be found all over the capital.

Michigan’s Original Pi Run, set at a distance of 3.14 miles – slightly shorter than your typical 5k run – will be held Saturday in Ann Arbor. It is sold out, but if you’re in the area, go to see Riley Mclincha, a man who once held the Guinness World Record for memorizing Pi to 7,500 decimal places, although he later beat his own record by another 2,500 digits. There’s also going to be a large assortment of pies for sale.

Princeton, New Jersey, will celebrate former resident Albert Einstein’s birthday, which happens to be March 14, with a full day of events, including various pie-related contests (eating, judging, throwing) and a Pi recitation contest. On the opposite coast, if you’re a kid (or if you have them) and you're in San Francisco, head to two museums in the Bay Area hosting Pi-themed celebrations Saturday, including one to teach children how to use a computer program known as Raspberry Pi.

Wherever you are, whatever you choose, know that this kind of day is indeed finite – it only comes around once in a century, and once in a lifetime for the majority of people – so enjoy it.
