hour
/ˈaʊ.ər/
A unit of time equal to sixty minutes or one twenty-fourth of a solar day. In astrology, it often refers to the planetary hour, a division of the day or night ruled by one of the seven traditional planets according to a repeating sequence.
In astrological practice, planetary hours are used to determine favorable or unfavorable times for specific actions, rituals, or elections. Each hour is governed by a planet that influences the quality and tone of that period. The sequence begins at sunrise with the ruler of the day’s planet (for example, the Sun on Sunday, the Moon on Monday, and so forth) and follows the Chaldean order: Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon. Understanding planetary hours helps astrologers attune timing to celestial rhythms and harmonize human activity with planetary energies.
