Happy Pie Day everyone! I’m sure you are all busy calculating decimal points and whatnot and eating and/or throwing a desert confectionery. Also, this is Einstein’s birthday so you might be cerebrating that as well. Can’t decide which one you like better? Don’t worry, it’s all relative.

Did you know there is an exact best time to celebrate Pi Day? If you’re going celebrate 3/14 for the sake of pi, you might as well go all out and time it to its most common approximation, 3.14159. Meaning, break out the party hats and baked goods on 3/14 at 1:59.

If, for some unlikely reason, you don’t know what Pie Day is here’s an explanation from Wikipedia:

Pi Day is an annual US celebration commemorating the mathematical constant π (pi). Pi Day is observed on March 14 (or 3/14 in the U.S. month/day date format), since 3, 1, and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.

In the year 2015, Pi Day will have special significance on 3/14/15 at 9:26:53 a.m. and p.m., with the date and time representing the first 10 digits of π.

Pi Approximation Day is observed on July 22 (or 22/7 in the day/month date format), since the fraction 22⁄7 is a common approximation of π.

Pi Day has been observed in many ways, including eating pie, throwing pies and discussing the significance of the number π.
Some schools hold competitions as to which student can recall Pi to the highest number of decimal places.

The Massachusetts Institute of Technology (MIT) has often mailed its application decision letters to prospective students for delivery on Pi Day. Starting in 2012, MIT has announced it will post those decisions (privately) online on Pi Day at exactly 6:28 pm, which they have called “Tau Time”, to honor the rival numbers Pi and Tau equally.

The town of Princeton, New Jersey, hosts numerous events in a combined celebration of Pi Day and Albert Einstein’s birthday, which is also March 14. Einstein lived in Princeton for more than twenty years while working at the Institute for Advanced Study. In addition to pie eating and recitation contests, there is an annual Einstein look-alike contest.

Please, when researching this do not get “American Pie Day” confused with “American Pie Council” because they are two completely different things.

Also, on a related note, there’s an American Pie Council. Because we need that.
