Planetary Hours

Planetary Hours divide each day and night into 12 unequal hours, with each hour ruled by one of the seven classical planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn). The sequence always follows the Chaldean order. The day's first hour is ruled by the day's ruling planet (Sunday = Sun, Monday = Moon, etc.). Planetary Hours are used in magical timing, electional astrology, and daily planning. Arcanavana calculates current Planetary Hour in real time.
