The Dragon's Demand
Like most of Avistan, the Empire of Taldor relies on Absalom Reckoning to measure the passage of days and years.
The Absalom Calendar divides the year into twelve months of approximately thirty days apiece. Each of the twelve months is dedicated to one of the many gods of Golarion.
There are seven days in the Absalom week: Moonday (auspicious day for nighttime religious ceremonies), Toilday, Wealday, Oathday (an auspicious day for signing contracts and swearing oaths), Fireday (often a market day), Starday, and Sunday (a day of rest and religious observation).
