Planetary hours are an ancient system that divides the day and night into 24 segments, each ruled by one of the seven traditional planets: Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon. The order follows the Chaldean sequence (Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon), repeating throughout the day and night. Arthyr Chadbourne had talked about this in his book on Chaldean Astrology, and many of the notes that were taken in his classes discuss this in greater detail.
How Planetary Hours Work:
The first hour after sunrise is ruled by the planet of the day (e.g., Sunday’s first hour is the Sun).
The sequence continues in the traditional planetary order.
Each planetary hour’s length varies with the season since daylight and nighttime are not always equal.
Why Learn Planetary Hours?
Timing: In astrology and magic, certain actions are believed to be more effective when performed during the hour of a sympathetic planet.
For example, Venus hours are good for love matters; Mercury for communication or study; Mars for courage or assertiveness.
Horary and Electional Astrology: Understanding planetary hours helps when choosing auspicious times for events or answering questions.
Personal Rhythm: Some people use planetary hours to align daily routines with planetary energies.
