The prime factors of 365 is 5 and 73, hence a month should either be 73 days and there should be 5 of them, or there should be 73 months with 5 days each.
Mathematical perfection!
Yes also 364 days from 13x28 would not align with years around the sun. We'd still need a leap year with 5x73 but that's easier than correcting from 364.
12x30, 5 or 6-day intercalary (government-mandated) days off for rest and celebration of Yule + New Year's (just make them all December 31-35/6).
