Calendar

Years are marked since the founding of the last great empire by Aroden, the Last Man. Although the empire has collapsed, its calendar remains in use to this day.

The months in Golarion correspond to our own, with each new year starting shortly after the solstice. Each month is etymologically tied to a specific god—residents of Golarion see the gods reflected in the changing of the seasons, and their names for the months reflect this.
