Calendar

The Inner Sea Region uses the Absalom Reckoning (AR) Calendar system, based on the founding of Absalom by the Last Azlanti, Aroden.
Each day has 24 hours, each week 7 days, and there are 52 weeks in the year, subdivided into 12 months.
Moonday: Generally a work day with some religions holding ceremonies at night. Toilday: A work day. Wealday: A work day. Oathday: A work day on which it is often considered advantageous to sign contracts and oaths. Fireday: A work day that is most often the market day. Starday: A work day. Sunday: Generally a day of rest and one devoted to religious observances.
