I haven't come up with any names yet, but I have been thinking about it. I've decided that since the calendar is Coruscant based, the months would have to be derived from the ancient Coruscant language of Notron Cant, which Ben Burtt based on Old High Germanic. So I was thinking of some combination of Old High Germanic months, the Roman tradition of basically naming months "seventh month", "ten month", etc., and maybe a planet or two from the Coruscant system. I just wish there was something I could extrapolate from, just one month name concretely established. I know this is the fanon thread but for something as important as the names of the months I just don't feel comfortable completely fabricating them wholesale. What approach did you take?
