Happy Dec. 12, 2012!

By Meagan McCrary
Good news: The world isn't going to end today (that won't possibly happen until 12/21/12). But it is the last time the month, day and year will all be the same number—at least until January 1, 2101. Consecutive date sequences are both magical and mystical for their rare occurrences and the hidden meaning of numbers.

Because 12 can be so easily divided, it's commonly used in measurements. There are 12 inches in a foot, 12 ounces in a troy pound (which is used to measure gold, silver and gems), 12 in a dozen, 12 hours on a clock, 24 hours in a day, and 12x12 (144) equals a gross.
