This was later adopted as the usual for the Jewish calendar. The approximate equivalence of the human menstrual cycle and the 30 day orbital period of the Moon which produces lunar phases led to the idea that the heavens, and the Moon particularly, were associated to fertility.(What’s the Moon’s section proper now ?)
