After its 14 days of waxing, culminating with the Full Moon, the entire process is reversed and the Moon decreases in apparent size. After about 3 days of appearing to be more or less full, the moon slowly begins to visibly go dark on the right side, while the left side stays the same disk-shape as it had when it was Full. This is the Waning Gibbous Moon -- it looks perfectly round on the left side, but bulged out past half-way on the right. This is the time to begin waning, repelling, decreasing, or reversing spells.
The Waning Gibbous Moon
rises in the early evening
and sets some time after sunrise.
Every night the Moon rises in the East a little later and the thickness of the Waning Gibbous gets thinner, until the shape of the Moon is half a circle. This is the Last Quarter, also called by some people the Third Quarter or Waning Half Moon. It is dark on the right and bright on the left. You can continue to do waning, repelling, decreasing, or reversing spells.
The Waning Last Quarter Moon
rises about at midnight
and sets about at noon.
As the shape continues to shrink, night by night, the Moon becomes a Waning Crescent; the dark side is to your right, more or less, and the bright Crescent is to your left. You can continue to do waning, repelling, decreasing, or reversing spells. This is a powerful time to take off curses or to send evil back to the one who sent it to you.
The Waning Crescent Moon
rises between midnight and dawn,
but fades out when the Sun comes up.
