Planetary Hours Calculator
The short answer
Planetary hours are time periods governed by different planets in astrology, each lasting approximately 60 minutes. They follow a specific sequence based on ancient astrological traditions, with each hour ruled by Mercury, Venus, Mars, Jupiter, Saturn, Sun, or Moon. Using our planetary hours calculator, you can identify the best timing for specific intentions—whether launching projects, making important decisions, or performing spiritual rituals aligned with favorable planetary energy.
Free planetary hours for any location and date: daylight divided into twelve hours and night into twelve more, each ruled by a planet in the Chaldean order (Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon), starting from the day's ruler at sunrise.
