12

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.)
