in 1453.E.J. Bickerman, ''Chronology of the Ancient World'' (Ithaca: Cornell University Press, 1968), pp. 81f The Canon only increments by whole years, specifically the ancient Egyptian year of 365 days. This has two consequences. The first is that the dates for when monarchs began and ended their reigns are simplified to the beginning and the ending of the ancient Egyptian year, which moves one day every four years against the

.Bickerman, ''Chronology of the Ancient World'', p. 107 The second is that this list of monarchs is oversimplified. Monarchs who reigned for less than one year are not listed, and only one monarch is listed in any year with multiple monarchs. Usually, the overlapping year is assigned to the monarch who died in that year, but not always. Note that the two periods in the Babylonian section where no king is listed the first represents two pretenders whose legitimacy the compiler did not recognize, and the second extends from the year Babylon was sacked by

.Leo Depuydt, "More Valuable than All Gold": Ptolemy's Royal Canon and Babylonian Chronology, Journal of Cuneiform Studies, vol. 47, pp. 97-117, 1995 The Canon is generally considered by historians to be accurate, and forms part of the backbone of the commonly accepted chronology from 747 BC forward that all other datings are synchronized to. It is not, however, the ''ultimate source'' for this chronology; most of the names and lengths of reigns can be independently verified from archaeological material (coinage, annals, inscriptions in stone etc.) and extant works of history from the historical ages concerned.
