It has mainly to do with the Sumerian numbering system, which was sexagesimal, i.e., base 60. In a sexagesimal system, the number 60 is as round as 100 in our base 10 system. Our units of time have their origins in ancient Sumeria, as do our units of angle measure, which is why there are 360 degrees in a circle. The day consists of 24 hours because a duodecimal (base 12) system was also in use by some civilizations.

It is all originated as concept. Then it evolved and refined because there are 360 degrees to a circle. Divide that in equal portions by 60 degrees. Further divide each degree and call it a minute. Divide even further to refine it and call it a second.
Earth's rotation in degrees and the time it takes for its orbit around the sun were calculated and the number 24 was arrived at to apportion the time. All this was done many many years ago.
Smart right?
