For 12/12/12, I decided to give 3 facts about the number 12, one for each 12 in the date:

12 is a superfactorial number - it is      1! x 2! x 3!

12 is the smallest abundant number.  (An abundant number is a number whose proper factors add up to more than the number itself.  The proper factors of 12 are 1, 2, 3, 4, 6 which add up to 16.

12 is the largest number with just one syllable.

Some ancient societies used a base 12 number system.

(OK, that is four facts.  But I couldn't decide which to leave out.)


  1. Just found this about 12, talking about the number of ways it can be evenly divided.!

  2. Apparently this date is very popular for weddings. I wish I'd known :(
