| Re: Fictional Calendar System Are you looking for "realism" in the world? Five times the size with its increase in gravity will make the people different from us and probably change the atmosphere mix.
Ignoring that, have you decided on the anything astronomical? Having more than one sun and/or more than one moon, or a VERY regular asteroid or comet would allow for those being used as part of the calendar.
Incidentally, why should the size of the planet affect the number of months in the year? You'll need to decide on distance from the planet to the nearest sun(s), and from then the number of days within the year; I'm guessing you still have days? What about hours or equivalent for sub-dividing the days? Got distracted... You're seeming to need more months by making the planet bigger - is that needed? The "month" is simply the number of days (variable or fixed) which the local people (or probably their long distant ancestors) chose to make. Or, like Earth, there could be several competing sets of month? Obviously, if you ARE moving the planet out in orbit, away from its sun, the temperatures are going to drop correspondingly, to the point that carbon-based life probably won't live. |
