The Five Cursed Days
Learning that Nut would bear a child to seize the throne, the sun god Ra cursed her to give birth on none of the three hundred and sixty days of the year. The wisdom god Thoth gambled with the moon and won five extra days of light — days that belonged to no former year. In these "days outside the year" Nut bore, one after another, Osiris, Horus the Elder, Set, Isis, and Nephthys. The structure of the Egyptian calendar — a year of 360 days plus 5 "epagomenal days" — was thus written into the myth: the birth of the gods was stolen from a seam in time.
