kinda right with the question bella. There was already 12 months in the clendar, and iam terrafied is right, the normads, after they setteled, relized the moon charts were wrong. BUt a few hundred years later, when rome was all in her beauty, augustine, and ocavious wanted thier days to be 31 days in the year. There fore, taking them away from febuary. august and october are the only 2 months that have 31 days back to back, becuase of that event. Im not too sure about Augustine wanting to have more days in his month then cesar though, so idk. as far as i knew, there was already 12 months in the year when rome was built, the eygiptains already built and created the clendar, along with the aztec's.
