Calendar System

The Keepers of the Earth and the countries in which they have cultural hegemony conceive of the world as cyclical, and as itself an entity. The Day of Death is a day in which the world is perceived to have died but not reborn yet, and thus disruption is possible on this day. The dead sometimes walk, extra-planar entities find it easier to traverse. There is a similar perceived construction within each month, with the fifth week being a time when magic is easier to access and more likely to act up.

They use a solar calendar, with the following time measurement units: In addition to the eight months in the year, there are also five "extra" transition days - Solstices and Equinoxes, plus a "Day of Death," which occur between months.
 * Year - 365 days/8 Months
