Planetary Hours

The Core Principle

Temporal Hours — The Heart of the System

Unequal hours are not a bug. They are the signature of this method: it binds timing to the Sun’s actual arc, not to a uniform clock.

What “temporal” means

In winter, daylight is brief; divide it by twelve and each day hour becomes short. In summer, daylight is long; the same division yields long day hours. Night hours behave inversely.

Why practitioners care

  • ✦It keeps the system local (place-bound) and seasonal (time-bound).
  • ✦It preserves the logic of a solar-anchored ritual calendar.

Sanity check

If a calculator shows identical 60-minute planetary hours year-round, it is not using temporal hours.
