July 22, or as it’s affectionately called across the Atlantic, 22/7, is Pi Approximation Day. But don’t let the name fool you. Unlike the more widely celebrated Pi Day (observed on March 14), 22 divided by 7 is actually a slightly closer approximation of Pi than 3.14.
The tradition dates back at least to 1995, when students at Chalmers University of Technology in Gothenburg, Sweden, celebrated July 22 by
“eating waffles and consuming Swedish Punch in various highly unlikely ways. There was also agitated discussion about how circles would look, if the ratio of their circumference to their diameter would equal 3.”
It just doesn’t get wilder than that. Later observances included the creation and digestion of the obligatory “Pi Pies”.

Hey! Why not make this a government holiday! Then we could use the much easier, close-enough-for-government-work version of Pi: 3
PI approximation day??? NERRRRRRRRRRRRRRRRRRRRRRRDS!!! :)
Seems like a great day to celebrate.. depending upon if you are a mathematician or not.. since I suppose those are the ones most likely to enlighten it in the first place. =)
That´s nice…didnt know that, good post.
