Planetary Hours: Calculator and Per-Planet Hour Guides
A planetary hour is one-twelfth of the time between sunrise and sunset (a day hour) or between sunset and the next sunrise (a night hour). Each is ruled by one of the seven classical planets in Chaldean order. This page is the map of the cluster: use the calculator for a live table in your city, and the per-planet pages below for what each ruler means and what to time to it.
