It is believed that the axis of the temple was positioned by the ancient Egyptian architects in such a way that on October 22 and February 22, the rays of the sun would penetrate the sanctuary and illuminate the sculptures on the back wall, except for the statue of Ptah, the god connected with the Underworld, who always remained in the dark. People gather at Abu Simbel to witness this remarkable sight, on October 21 and February 21.
On February 22, a day celebrating the king’s birthday and again on October 22, a day celebrating his coronation, sunlight illuminates seated statues of the sun gods Re-Horakhte and Amon-Re, as well as a statue of king Ramses II. The statues sit in the company of the Theban god of darkness, Ptah (who remains in the shadows all year).
Due to the displacement of the temple and/or the accumulated drift of the Tropic of Cancer during the past 3,280 years, it is widely believed that each of these two events has moved one day closer to the Solstice, so they would be occurring on October 22 and February 20 (60 days before and 60 days after the Solstice, respectively).
