Thobel cannot have a Julian Calendar; Julias Caesar never existed there. Eliza spent a bit of time thinking about time -- how our technology grew in a pretty short span of time (all things considered). When creating a world for Thobel, where technology is quite a bit behind ours, there were two things that really struck her. First, technology might not move at the same pace because magic changes necessity, and second, the people of Thobel shouldn't mark time in the same way when their circumstances aren't the same as ours. Without a religious revolution to restart time necessitating counting backward for time previously, there cannot be common era or before common era. Nevertheless, they probably need more than a thousand years of history and pre-history. Research into calendars of ancient peoples proved how often humans tend to think in terms of a thousand years as if it marks beginning and end. Thobel is populated by people with a technological level equal to pre-renaissance. Named millenia were born.
Eliza liked the idea that millenia might be named individually, and that they might bear names of the sun and moons -- items that might have been thought deities in the past. In "Something Special", you see a book that declares the current year as "Millennium of Raj, 635". By this you can probably guess there were other millennia. In fact, the previous was the Milennium of Kubi. Prior to that was the Milennium of Elis, a great deal of which is just like our BCE in that it is marked by archeological finds rather than actual recorded history. Why doesn't Thobel mark time back millions of years? They aren't that scientifically savvy yet.
Thobel has a more perfect year. It has twelve months with 30 days in each. No bouncing around of how many days in a month. No leap years or skipped years to make up quarter days. It is likely that Thobel isn't measuring its rotation perfectly, but then they are technologically behind Earth.
Thobel's months have their own names. Here they are in order:
Thobel's days also have different names. Here they are in order:
How often have we Earthlings wished for more hours in a day? You might want to move to Thobel then. While we have 24, they have 28. Seven is a seriously magic number there.
Moonrise on Thobel could never be precisely the same as Earth. For one thing, there are two moons, though they usually only see one every three days. For another, the closer moon isn't exactly round. It's missing a notch.
Our solstices and equinoxes are close to the same day of every third month, but not exact. With a calendar of 360 days, the math is much more simple.
With a 28 hour day, midday would be 14 o'clock -- something Earth simply doesn't have. The closest we can come is 1400 hours military time, which is 2:00 p.m. However, if you're looking for when Ellis is at it's straight up point it would be 14 o'clock. But they don't have watches.
Midnight originally was the end of the clock, still many hours until dawn. If you see a midnight in "Something Special" or its sequels, the intention is not a specific time necessarily. Even Cypress' fantastic water clock usually doesn't mark this time since it has long since run out of water.
Thobel hasn't thought up daylight savings. Yes, they have less daylight hours in winter, though magic can certainly light up the dark.
