π 3.141593

Published July 22, 2010

πToday, technically is Pi Approximation Day but some people consider today the official (unofficial holiday) of Pi Day. The day was founded by Larry Shaw and it is a day for math geeks to be even geekier.

Pi Day is typically on March 14th, i.e. 3/14, which is close to the value of Pi (π) 3.1415926. But technically, today, 22/7 (European style) is an even closer value to Pi (π). Yea, 227 is one of the closer approximations to π.

For more information on the unofficial holiday, see Wikipedia.

We do somewhat celebrate it here by having Mabe design special themes for the Search Engine Roundtable. Here is today's theme, followed by some older themes:
