Saturday is Pi Day, and if you haven't celebrated before, it's a great time to start.
Every year, pie lovers celebrate 3-14, the day when love of math and love of baked goods come together. The date reflects the same first three numbers in the mathematical constant pi -- 3.14. Many people celebrate by eating the edible type of pie, not the imaginary number kind.
Celebrate with fruit pies, pizza pies or pie shakes, but however you celebrate, do it well, because this day only comes around once a year.
