Pi Day: How To Celebrate Our Nation's Nerdiest Holiday

Julie Ryan Evans

piMath geeks of the world, rejoice -- Monday, March 14 is Pi Day. No, that's not a typo, it's Pi with no "e" on the end. Personally, I prefer it with the "e," but there's another day for that. So yes, Pi it is -- a day set aside (on the fourteenth day of the third month) to celebrate 3.14, that mathematical constant known as Pi.

Never heard of the holiday before? You're not alone. It's a relatively new one as far as holidays go. The first recognized celebration of the day was held by physicist Larry Shaw in 1989. In 2009, the U.S. House of Representatives passed a resolution making the holiday official; and perhaps most significant for the day -- last year it was honored in the Google Doodle. So yes, it's the real deal.

It pales a bit in the shadow of the upcoming St. Patrick's Day, but who doesn't love another reason to celebrate? Here are some ideas on how to commemorate Pi Day, even if you don't have any clue how to use Pi.

Send a Pi Day Greeting Card Oh yes, there are cards to celebrate this day. These Pi Day ecards will be an unexpected light in someone's day, and just think how smart you will look.

Listen to Pi Day Music Again, yes, it's really does exist. This Pi Day Song was composed based on the numbers of Pi to 220 decimal places. I'm not quite sure what that means, but it sounds lovely.

Balance Your Checkbook You may not use Pi, but you are using numbers, and it's a good excuse to get your finances in order.

Wear Pi  From jewelry to hoodies, you can show your math pride. The holiday comes around every year, so order now for years to come if your wardrobe is without Pi apparel.

Eat Pie  Don't let a vowel get in the way, pie is the perfect celebration of Pi. Whether you bake one up or grab one from local bakery, indulge for the sake of math!

How will you celebrate National Pi Day?
