# 12/12/12

I don’t usually obsess about dates, but as this one won’t pop up in the calendar again for a century, I thought it was worthy of mention. The number 12 has a peculiar significance across a variety of fields, from mathematics, to the sciences, to religion, to history.

I try not to attribute any mystical import to this fact, as it’s true of most numbers, and as at least one author has observed, dalliance with numerology, the “harlot sister of mathematics,” inevitably ends in despair and empty pockets.

Anyhow, here are some fun facts about the number twelve. Yes, I cribbed most of these from Wikipedia:

Twelve is magnesium’s atomic number (number of protons).

The baker’s dozen originated as a way to forestall harsh penalties levied in 13th Century England under the reign of Henry III against bakers who shortchanged their customers. It’s also known as The Devil’s Dozen. Coincidence? I think not!

Though there are 11 players on the field for each side in an American football game, the home crowd is commonly called the “Twelfth Man,” due to its perceived influence on gameplay. There are twelve players to a side in the Canadian Football League.
