mark your calendars! pi day is March 14


Nerds around the world, sharpen your pencils and shine your calculators — Pi Day is upon us again. Every year, 3/14 is a day we set apart to celebrate Pi, the mathematical constant describing the ratio of a circle’s circumference to its diameter, because the first three digits are 3, 1, and 4. Last year, the U.S. House of Representatives passed a non-binding resolution (H.RES.224) recognizing the holiday, which is also Einstein’s birthday. That’s all the justification I need to party.


Because this year’s celebration, isn’t until next Sunday, we have plenty of time to get our pi-parations in order. Visit to learn more about the greatness that is Pi, or send your most deserving friends an e-card. Stock up on your Pi apparel, like this T-shirt from Neatorama or hoodies and housewares from ThinkGeek.


And get those Pi-cecubes a-chillin’ for their signature Pi-Tini, because once Pi Day eclipses, we’ve got 365 long ones until it’s here again. (Unless, of course, you count Pi Approximation Day on 7/22.) And if you need a little Pi year-round, check out Katie D.’s Pi dresser find for some furniture inspiration. — Sarah C.

Such a great post Sarah! Pi day is my favorite holiday EVER! 3.14 4 life!

Oh, no!!! I’m going to be out of town and will MISS pi day this year! I always make a couple of pies and take them to work, and no one ever knows why! :) I love it! That pi-tini looks awesome — I’ll keep it in mind for next year!
