In Sunan, as with most risen nations, time is reckoned according to the Modern Era calendar, which anchors its reference point (year 1) at the foundation of the Old Kingdom. The current year is ME882 – eight hundred eighty-one years after the dedication of Nam Khomen. Events preceding the Old Kingdom are referred to as having taken place in the Antecedent Era; year AE1 was the year immediately before ME1. Note that the Modern Era calendar contains no year zero.
In the following table, ME dates are presented as positive numbers while AE dates are negative.
