Judicial Astrology dictated which hours of the day and night were ruled by which planet. It used the old separate hours of the day and night, with each sunrise being the first hour of the day. Sunday started with the hour of the Sun. Monday started with the hour of the Moon. Tuesday started with the hour of Mars. And so on throughout the week.
