What century did Shulgi reign for 48 years?
Babylonian calendar The Babylonian calendar was a lunisolar calendar with years consisting of 12 lunar months, each beginning when a new crescent moon was first sighted low on the western horizon at sunset, plus an intercalary month inserted as needed by decree. The calendar is based on a Sumerian (Ur III) predecessor preserved in the Umma calendar of Shulgi (c. 21st century BC).
Apiashal Apiashal had been an early monarch ("fl." "c." 2205 BCE — "c." 2192 BCE) of the "Early Period of Aššūrāyu" ("Assyria") according to the "Assyrian King List" ("AKL"). He is listed within the section of the "AKL" as the last of whom, ""altogether seventeen kings, tent dwellers"." This section shows marked similarities to the ancestors of the "First Babylonian Dynasty". The "AKL" also states that "Apiashal" had been preceded by his father "Ushpia" ("fl." "c." 2218 BCE — "c." 2205 BCE.) Additionally, the "AKL" states that "Apiashal" had been succeeded by his son "Hale" ("fl." "c." 2192 BCE — "c." 2179 BCE.)
