Reply to comment by rheller2000 in TIL French used 10h day instead of 24h between 1793 - 1805 during era called "decimalisation" by NightKnight_CZ

But 20 can be divided by 1, 2, 4, 5, 10, and 20.

Two fewer divisors than 24, but it's not too significant a change. You still get half and quarter days, nicer tenth and fifth days (i.e.: Integer divisors), and almost as nice eighth days (2.5, which is easier to do arithmetic with), but you get bad third and sixth days (repeating decimals).
