Few scholars now agree with the contention that Amenhotep III associated his son Amenhotep IV on the throne for several years of coregency; it is assumed here, in accordance with general scholarly consensus , that the older king died before his son gained power. At or shortly after the time of his accession, Amenhotep IV seems to have married the chief queen of his reign, Nefertiti . The earliest monuments of Amenhotep IV depict the traditional worship of deities executed according to the artistic style of the preceding reign—with the exception of a prominent role accorded to the falcon-headed god Re-Harakhte , who is given an unusual epithet containing the phrase “who rejoices in his horizon, in his aspect of the light which is in the sun’s disk.”

NB Unfortunately, I have discovered an error in the program used to generate this calendar, which has resulted in the weekdays in some of the monthly calendars in the regnal years section being displaced forward or backward by a day. The affected regnal years were those beginning in March or later, and either starting or ending in a leap year, and the affected calendars those centred on March until the end of the regnal year. This error has been corrected, 21 September 2002.
