Planetary Hours — Cosmic Timing

Planetary hours are an ancient timing system where each hour of the day is governed by one of the seven classical planets: Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn. The system dates back to Babylonian and Hellenistic astrology.

How Planetary Hours Are Calculated

Each day is divided into 12 daylight hours and 12 nighttime hours. The length of each hour varies by season. The first hour of the day is ruled by the planet associated with that day (Sunday = Sun, Monday = Moon, etc.). Subsequent hours follow the Chaldean order: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon.
