The innate human biological clock is nearer 25 hour-day than 24 hours,

Mine used to be synchronized to the television show schedule.

I suppose 24 developed out of need for dividing the day evenly.
Of course, that doesn't explain the 7-day week. LOL

The ancient Egyptians apparently were on a decimal system but got
derailed by a special interest faction in their standards committee
that favored a 12 hr day. At least they tried. I would give the
blame/credit to the Babylonians.
