7 Reasons 21 is Special (Hint: The Rapture Ain’t One of Them!)

So tomorrow the world is supposed to end. Okay, not quite. The rapture will begin.  Apparently Earth won’t be destroyed until October 21. So you have some time to get your $@*% together.

But this isn’t the only reason that the number 21 is significant. Here are some other interesting (in a pocket-protector kind of way) facts about this Very Important Number.

1. 21 is the sum of the dots on a die: 1 + 2 + 3 + 4 + 5 + 6 = 21
2. 21 is a Fibonacci number: 1, 1, 2, 3, 5, 8, 13, 21, …
3. 21 is the third “star number.”
4. 21 is smallest number of differently sized squares that are needed to tile a square.
5. 21 is the legal drinking age in the U.S. (Not so math geeky, eh?)
6. Blackjack baby!
7. {2²¹}-21 is a prime number.
