The Intercalary Days
Horus carries no Gaiad scripture — it stands apart as an intercalary period of 5–7 days modelled on the Ancient Egyptian epagomenal days. Each day honours a divine birth: Day 1 Osiris, Day 2 Horus, Day 3 Set, Day 4 Isis, Day 5 Nephthys (a Friday Sabbath). In 53-week years, Day 6 is the Saturday Sabbath and Day 7 is Sunday — New Year's Eve before Sagittarius 1 begins the cycle anew.
Horus is the intercalary month: 5 days in a common year, 7 days in a leap year (53 ISO weeks).
