Planetary Hours
Planetary hours divide daylight and night into twelve unequal periods each, ruled in turn by the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. The active period changes with local time and emphasizes themes such as visibility, communication, relationships, initiative, or restraint; read the variants by matching the current ruler with the task at hand.
In detail
Planetary hours are formed by dividing local daylight, from sunrise to sunset, and local night, from sunset to the next sunrise, into twelve equal parts apiece. Because the two spans change, a planetary hour is not necessarily sixty minutes. Rulership proceeds through the Chaldean order, and the relevant hour becomes active when local time enters its assigned segment. Interpretation begins with the ruler’s topics, then compares the task and the ruler’s constructive or difficult tendency: Venus and Jupiter generally assist, Mars and Saturn demand more caution, while the Sun, Moon, and Mercury emphasize authority, everyday responsiveness, and communication or exchange. The changing segment length is what separates this system from ordinary clock hours.

FAQ
- Are planetary hours always sixty minutes long?
- No. Local daylight and night are each divided into twelve equal segments, so their length changes with sunrise and sunset and may differ between day and night. For an accurate start and end time, use the local daily intervals rather than assuming each ruler changes on the clock hour.
- What activities are best for each planetary hour?
- The useful activity depends on the ruler. Venus and Jupiter hours generally support forward movement, Mars and Saturn hours call for tighter risk control, and the Sun, Moon, and Mercury emphasize visibility or authority, home and emotional responses, and communication or exchange. Match the task to the relevant variant before deciding whether to act or wait.
