Pi Day and Other Math Holidays

pi-day-300x225In honor of Pi Day being last week, I thought it would be fun to take a look at days of mathematical note. First, did you know that Pi Day (3/14) is also the birthday of renowned physicist Albert Einstein? Other mathematical holidays and observances include:

July 22: If you write your dates with the day before the month, as is standard in Europe, you’ll see that this date becomes 22/7. Since 22/7 is a fraction historically valued for its closeness to pi—at five decimal places it is 3.14285—July 22 is recognized by math enthusiasts as Pi Approximation Day. (If nothing else, it’s a great excuse to bake a pie!)

November 23—Maybe pi isn’t really your thing. You could always celebrate Fibonacci Day. The digits of this date form the first four numbers in the Fibonacci Sequence: 1, 1, 2, 3.

If you’re interested in mathematicians’ birthdays, you can find a calendar of those here. Coming up this month are Joseph Fourier (3/21) of the Fourier transform and Fourier series, algebraist and physicist Emmy Noether (3/23), and the famous Paul Erdös (3/26).

Do you have any favorite math holidays to celebrate?

    There is also Tau Day (http://tauday.com), Half Tau Day (http://halftauday.com) :). However, my new favorite is Pigeon Hole Day (http://annoyingpi.wordpress.com/2010/11/05/pigeonhole-day/).
