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.
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.

Mathematical perfection!
Problem here is there’s actually 365.25 days in a year, the .25 is why we have leap years.
Ok, thats fine, we’ll just… The factors of 365.25 are: 487¹×3¹×2⁻²
Wait…
Your mom has leap years

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).
