Pi Day is an international holiday celebrating the mathematical constant π. It is celebrated on March 14, i.e., 3/14 in month/day notation. It is typically celebrated by telling everyone you know, "Hey, it's Pi Day!" More enterprising people bake lots of pies, take pictures of them, and then post the pictures on the Internet.
After moving to the UK, where the date would be written 14/3, that choice for Pi Day seemed wrong, reeking of American cultural hegemony. There had to be a better way.
So I came up with one. Why not celebrate Pi Day on the 314th day of the year. In most years, this is November 10. This should be easy for everyone to remember, because it is the day after my birthday. In leap years, like 2012, Pi Day occurs a day earlier, on November 9.
Happy belated Pi Day!
