(RNN) -Tuesday is National Pi day, the one time of year that mathematics and baked good collide. Even people who aren't passionate about math can celebrate - with pie. Pi is the ratio of a circle's circumference to its diameter, a seemingly infinite measure. And since pie is circular - and delicious - it's part of the big celebration as well. 

The date, March 14, matches the first three numbers of pi: 3.14. The day has its own website that spouts facts and sells Pi coffee mugs. Princeton Pi Day is actually a week-long celebration of pi, and pie. Check out its Twitter account to keep up with the drama of the Pi Recitation Championships. 

Princeton's Pi Day also includes pie-eating contests and a birthday celebration for Albert Einstein, who was born on this day in 1879.

The Grand Traverse Pie Company in Michigan, which will dish out a free slice of pie with any purchase, hosts a Pi Day video contest. The participant who can rattle off the most digits of pi in 15 seconds gets free pie for life. Want to learn how to recite 600 digits of Pi? This kid may be able to help ... or he may confuse you even more. 

Despite the fun and games, Pi Day is no joke. In 2009, House Resolution 224 made March 14 National Pi Day - an official event. Physicist Larry Shaw of San Francisco's Exploratorium Science Museum is the founder. In 1988, he and his staff celebrated the first Pi Day by holding a circular parade and eating fruit pies.

And so the tradition began.

Here are some pi facts to throw out at your Pi Day party, courtesy of the YouTube channel MashUp Math and Live Science:

  • The time it would take to recite the 6.4 billion known digits of Pi without stopping is 133 years. 
  • Computers have calculated pi up to its 2,000,000,000,000,000th, or 2 quadrilliionth, digit. 
  • Favorite types of pie in the US, ranked in order, are apple, pumpkin, chocolate cream, cherry and pecan.
