19 National Pi Day Deals, Freebies and CouponsFrom Pizza Hut to Papa John's, check out these Pi Day deals for 2016.

National Pi Day 2016

National Pi Day falls on March 14 and math whizzes across the globe will join together to honor the mathematical constant pi. Pi is the ratio of the circumference of a circle to its diameter. This irrational number begins with 3.14 — hence the March 14 celebration — and is estimated to continue for 10 trillion digits. While the concept of pi has been alive for nearly 4,000 years, National Pi Day wasn’t established until 1988 by Larry Shaw, a physicist at San Francisco’s Exploratorium science museum.

Pi Day Celebrations

National Pi Day might be a little geeky, but math geniuses make it quite fun. Pi Day celebrations often center around the baking, eating and throwing of pies, with some revelers even participating in pi-recitation competitions. In 2015, those commemorating the occasion got to make a little Pi Day history by watching the clock strike 9:26:53 a.m. — equating to 3.141592653, the first 10 digits of pi — a phenomenon that happens just once every one hundred years.

Government recognition of Pi Day has even helped bring it to the classroom. On March 12, 2009, Congress passed a measure to support National Pi Day as a recognition of the significance of National Science Foundation math and science education programs. Schools are encouraged to celebrate the day with activities that help students learn about Pi and make math fun.

Pizza Hut’s National Pi Day Contest Could Earn You Free Pizza

You’ll have to work a little bit for this deal; but free pizza for 3.14 years seems worth it. On March 10, Pizza Hut announced their partnership with math genius John H. Conway to have a contest on Pi Day. The game is simple: Conway will write three complex math problems on Pizza Hut’s blog. You must comment your answer — each comment is time-stamped — and the first person to get each right has the chance to win free pizza for 3.14 years. That’s a lot of pie. The contest begins on March 14 at 8 a.m. EST and the prize will be awarded in Pizza Hut gift cards — totaling almost $1600.
