Orr's calendar was first developed by the Oreads long ago. Besides the regularity of a day, the most easily observable regular phenomenon was that of the lunar cycle which tracked at a consistent twenty eight days. This, along with four recognizable seasons became the basis for their calendar. Originally, the days of the week were: Starday; Sunday; Moonday; Firesday; Watersday; Earthday; Airsday. As the other races found their way into relevance and adopted the calendar, some days were renamed by various cultures and at different times. Currently, most peoples have settled on the following naming convention: Starday; Sunday; Moonday; Godsday; Watersday; Earthday; Freeday.
