WHY does a dozen bear a separate name?

For it has many divisors

A dozen is the smallest number that has six different divisors, four of which are in a row: 1, 2, 3, 4, 6, 12. It is convenient in use, so counting in dozens was used in some monetary systems and in cattle breeding, where derivatives were also used.

Inch dozens are grosses (144) and dozen grosses are masses (1728). We are left with the division of the dial into 12 hours and the word "dozen" from duodecimal counting.
