Why are there 24 hours in a day, 7 days in a week, and 12 months in a year?

the sun and moon cycle takes up 24 hours, so that is why a whole day is considered 24 hours. there are 7 days in a week based on the earths rotation and position on its axis. there are 12 months in a year because of the lunar cycles, there are just a little bit over 12 in a year. we also have been following this stuff since the time of the ancient babylons and maybe even before.

not completely sure but i think it’s many moons, smaller in size and a ring system.
