The Watcher of the Mists
The calendar of the Inner Sea region is a direct analogue of the real-world calendar.
Golarion (usually called “the world”) is a planet that orbits a single yellowish-white star (called “the sun”). Its day is 24 hours long, and its year is a little more than 365 days long. Every four years, a leap day is added.
The world has a single large moon (called “the moon”) that is the same apparent diameter as the sun. The moon completes its phases in slightly less than 28 days.
The calendar is divided into weeks of seven days each, and into 12 months that have between 28 and 31 days each. The days of the week are: Moonday, Toilday, Wealday, Oathday, Fireday, Starday, and Sunday. In most areas, Sunday is a day of rest and religious observance, and many businesses are closed. Oathday is the traditional day of the week to make promises, perform official ceremonies, sign contracts, or get married.
The months of the year, their number of days, and their real-world equivalents are:
*-Every 4 years (in years divisible by 4), a 29th day is added to the month of Calistril, except for years evenly divisible by 200. (Thus the year 4700 was not a leap year, but 4800 will be.)
Play in this campaign started in the year 4707. The current year is 4708.
