This has puzzled me for some time. Granted, a "day" is natural, as the earth turns, the sun appears to rise and set, and to take a while to cross the sky. But why 24 hours? And why divided into two 12s, A.M. and P.M. Who said?
I'm surprised someone hasn't beat me to this, thread-drift-wise.
Blame the folks as far back as Mesopotamia, but more likely the Romans.

Thank you. That's most informative. Except it doesn't explain why 12 or 24. Why not 10 or 20? Was there an epidemic of polydactylism? Since 10 fingers and 10 toes is the "norm", we tend to base our numerical systems on 10 (or 20 in the case of some New World cultures.)
