james.lab6.com— Why 24? Why not 10? Why not 60? Time is not naturally split up into 24 anythings, so the division must be totally artificial.

The time in a day is equal to the time taken for one complete rotation of the Earth. For simplicity, the time is rounded off to 24hrs. If you didn't know that, your schooling must have gone wrong somewhere.
This article is too long - wikipedia sums it up in a paragraph:The hour was originally defined in ancient civilisations (including those of Egypt, Sumeria, India and China) as either one twelfth of the time between sunrise and sunset or one twenty-fourth of a full day. In either case the division reflected the widespread use of a duodecimal numbering system (counting with each thumb the spaces between the joints of the other finger on the same hand, i.e. 3 x 4 = 12) and the equally widespread tendency to make analogies among sets of data (12 months, 12 zodiacal signs, 12 main compass points, 12 hours, a dozen).
I agree, this article is remarkably hard to read (something about the author's writing style), and it's summed up much more succinctly by wikipedia. No digg
