Nut and Geb had sex. When Shu heard about this, he did not want them to be together. He became the air between the sky and ground. He also said that the pregnant Nut could not give birth. Nut begged Thoth to help. Thoth gambled with the moon-god Khonsu. He won five more days to be added to the 360-day year. Nut had one child on each of these days: Osiris, Isis, Set, Nephthys, and Horus-the-Elder.
