What is a planetary hour?

A planetary hour is one twelfth of daylight (sunrise to sunset) or one twelfth of the night (sunset to the next sunrise). Each hour is associated with a planet from the seven classical planets in the Chaldean order.

How are planetary hours calculated?

Daylight is divided into 12 equal hours from sunrise to sunset, and night into 12 equal hours from sunset to the next sunrise. The ruler of each hour follows the Chaldean order: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon. The first daylight hour is ruled by the planet of the weekday.

⚠️ Important note

Planetary hours are a tool for boosting effectiveness and harmonizing your activities, not a rigid dogma. If you urgently need to sign a document or see a doctor, don’t put it off just because of an «unsuitable» hour. Common sense, real circumstances and your personal responsibility always take priority over astrological recommendations.

How to pick an hour: 5 steps

Identify the sphere of your task — it points to the ruling planet.
Find the nearest hour of that planet in the table; a safe choice is Jupiter or Venus.
Day planets (Sun, Jupiter, Saturn) favor daytime; night planets (Moon, Venus, Mars) favor nighttime.
Time is strong when the hour’s planet is “friendly” with the day’s planet.
Check the Moon phase and hours marked with caution.
