❖ Tool · Hour & Day
The ancient sunrise-to-sunrise clock. Each day is ruled by one planet; each hour within it by another, stepping through the Chaldean order. What you're doing now is happening in one specific hour's atmosphere.

Twelve day hours (sunrise → sunset) and twelve night hours (sunset → next sunrise), each stepping through the Chaldean planetary order. Times shown assume a 6 am / 6 pm anchor — share your location for precise hours.
Day hours
Night hours
A planetary day runs from sunrise to sunrise. The day's ruling planet is given by the weekday (Sunday / Sun, Monday / Moon, Tuesday / Mars, and so on). The twelve daylight hours and twelve night hours then step through the Chaldean order — Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon — starting with the day's ruler and cycling continuously.
Hours vary in length: a summer "day hour" is longer than a winter one, because daylight itself is longer. What stays constant is the sequence — the atmosphere of each hour, regardless of its clock-length.
