There are three principal calendars in common use in Cerilia today: Masetian Reckoning (Ma), used by the Khinasi; Haelyn's Count (HC), favored by the astronomers and scholars of Anuire, and commonly used elsewhere in Cerilia; and Michaeline Reckoning (MR), in common use in Anuire and Rjurik. Masetian Reckoning starts its count of years from the first arrival of humans in Cerilia, at the end of the Flight from Shadow. Haelyn's Count begins with the ascension of Haelyn as a god, at the Battle of Mount Deismaar. Michaeline Reckoning is dated from the death of Michael Roele.
