Dark Sun Calendar

Every city state has its own calendar, but that most
commonly used and considered the Calendar of Tyr.
In the calendar of Tyr, years are counted off using
a pair of concurrently running cycles; one of eleven
parts, the other of seven. The eleven-part, or
endlean cycle, is counted and spoken first, in the
order presented below. The seven-part, or seofean
cycle, is counted and spoken second. The endlean
cycle is complete when Athas two moons, Ral and
Guthay, meet in the heavens, a major eclipse that
occurs once every 11 years. The seofean cycle is
more abstract, meeting when agitation in the cosmos
leads to fury.

Every 77 years the cycle repeats itself, ending with
a year of Guthay’s Agitation and starting again
with a new year of Ral’s Fury. Each 77-year cycle is
called a king’s age; there have been 183 complete
king’s ages since Tyr adopted this calendar (more
than 14,500 years).

So, the first year of each king’s age is a year of
Ral’s Fury. The next year is a year of Friend’s Contemplation,
followed by a year of Desert’s Vengeance,
etc. The 76th year of each king’s age is a year
of Enemy’s Reverence, followed by the 77th year, a
year of Guthay’s Agitation.

Superstition and folklore surrounds each of the
years of the king’s age. Storms during a year of
Wind’s Vengeance are believed to be more powerful
and dangerous, so many overland trips are avoided.
Sacrifices and prayers are called for to ward off the
great beast during years of Dragon’s Agitation.
Years of Enemy’s Contemplation are supposed to
enliven treaties and alliances-the list goes on.
