The day ruler
Sunday=Sun, Monday=Moon, Tuesday=Mars, Wednesday=Mercury, Thursday=Jupiter, Friday=Venus, Saturday=Saturn.
This ruler determines which planet governs the first daylight hour after sunrise.
The hour ruler
The hour ruler is assigned by the Chaldean sequence, hour by hour. It is the ruler you actually work under.
How this fails in practice
- ✦Choosing a “good day” and ignoring that the acting hour is ruled by a planet contrary to the aim.
- ✦Resetting the sequence at midnight and shifting every ruler after that point.
