If you have a 28 day month then you have four seven day weeks in a month and 13 months in a year with just a day and a quarter left over.

7 X 4 X 13 = 364

I'd bet that simple calendar system was rejected for religious regions -- all the patriarchs telling everyone 12 months was the law and 13 months was unlucky for, um, reasons...

The period of the moon's orbit as measured with respect to the stars is about 27.3 days, and 29.5 days with respect to the sun.

The relationship between "month" and "moon" is clear. Lionel Mandrake Oct 2022 #5

That 29.5 days wrt the Sun makes it closer to 12 "months" than 13 in a solar year muriel_volestrangler Oct 2022 #7

A calendar of 12 months of 28,29,30,or 31 days makes more sense? hunter Oct 2022 #8

I don't think you can call it an "overt rejection" muriel_volestrangler Oct 2022 #9
