Like with all naturalistic calendars, this one is as old as the people who use it. Names first started off as simple descriptions of the respective month's most characteristic trait before slowly evolving into well established, static names.
But just as cultures change over time, this calendar of largely oral tradition changes along with it.

This particular lunar calendar is rarely used in upper classes or cultures where agricultural events upheld higher importance to daily life, however, sometimes certain names overlap with other calendars due having a similar origin of describing the changing nature.
