You can, if you wish, use angelic rulers instead of planetary ones for the magical hours, or combine the energies of both.
In practice, if your magick has a spiritual focus or is concerned with healing or global or ecological matters, angels work better than planets.
If you have calculated your daily planetary hours, your angels will correspond exactly.
As with the planets, each archangel rules the first hour after sunrise of his own day.
Though many people do regard the Archangels as male, they are androgynous and so I have called them ‘he’ merely for convenience.
Many magicians from the Middle Ages onwards have used angels as part of formal rituals.
They have long been a potent form of psychic protection both for guarding the four corners of the ritual circle and as personal guides in less formal magick.
