An American abbreviation for today's date is 3/14/15, which lists the first five digits of the decimal expansion for pi. That won't happen again for a hundred years.
Next year's Pi Day will also be special: 3/14/16 looks like 3.1416, which is the best five-digit approximation to pi.
Europeans are out of luck. Spock would approve of their system (day, month, year), which is more logical than ours. Alas, in Europe today is 14/3/15, which has nothing to do with pi. The European Pi Day will be 3 January 2041 (3/1/41), which captures only four digits of pi.
WARNING: Those allergic to math should not read the following statement.
When Spock said that pi is transcendental, he meant that pi is not a root of any polynomial with integer coefficients.
