So it's been a good long while since I've been on this site, mostly because I haven't been doing any writing for awhile. Life kind of got in the way, but now I'm getting some really good ideas, so I'm working again.
Most of what I've been working on is world building. I've completely revised my working map, established a more complete political and legal system, and I'm currently working on creating a complete history. When I set down to build the history I realized that I needed a calendar system as a point of reference. I've got the basics down pretty well, but the calendar is only used by one of the cultures in this world called Elenia (the culture is analogous to Scandinavia and Northern Europe). In my notes, the calendar was created to be more accessible than the one used by the priesthood of the culture of Kheph (analogous to Babylon/Egypt/Maya) which is very complex and has to do with the 72 stations of the God-King battling the forces of darkness. Also, there is an ancient culture that has disappeared, but still plays a significant role in the history of the world (analogous to Atlantis/Anunnaki/Elven). I haven't named this culture or put down a lot of information about them, but I've been considering making them have a lunar calendar instead of a solar calendar.
So as a result, I've got three calendar systems that will end up overlapping to some degree, one of which won't even be based on the solar cycle. And if I'm going to expand my history to include those other cultures, I'm going to need some way of cross-referencing these systems so that they are consistent.
I was just wondering if any other fantasy writers out there have taken their world building to this level, what problems they've encountered, and what they did to resolve them. Thanks.
