Time on Therafim is presently very hazy, and loosely linked to time in the real world. To help organize things a bit better, there needs to be an established calendar, starting from the basics on up. How long is a day, for instance? (Therafim is larger than Earth, the additional density partially explaining how its inhabitants are much hardier than those of our world - the presence of magic infusing everything explains the rest.) How many days are in a month? In a year? What are the names of the months? Are there any superstitions on Therafim related to the time of someone's birth (ala zodiac signs)? Has the way that time is measured changed over time? Do different parts of Therafim use different ways to measure the passing of days, months, and years? Filling out this information will provide another layer of texture to the world.
