Wicca and many other pagan religions follow the cycle of the moon as well as the sun (Sabbats).
The Moon holds great importance for Wiccans. First of all, it is a symbol of the Goddess, but we are also acutely aware of the effects the moon has on Nature, and on ourselves. Many Wiccans perform spells and rituals according to the current phase of the moon.
The Full Moon
The full moon is the point at which we can see an entire side of the moon. For many Wiccans and Pagans, this is a time to celebrate with an Esbat ritual. In many traditions, this is a good time to do rituals that greatly increase abilities or heal.
The Waning Moon
The waning moon is the period during which the moon goes from full to dark once again (wanes from Full to New). In many traditions of Wicca and Paganism, this time of the month is used to do “baneful” magic (reduce) — that which sends away, gets rid of or destroys things you no longer wish to be burdened by, banish harmful energies.
The New Moon (Dark Moon)
The new moon is sometimes tricky to work with because you can’t always see it during this phase – it will appear as a very faint crescent of silver low on the horizon, if you can see it at all.
The Waxing Moon
The waxing moon is the period during which the moon grows from dark (New to Full). It takes approximately fourteen days for this to happen. In many magical traditions, people use this time of the moon to perform “positive” magic — in other words, magic that draws things to you, or increases things, draw things to you.
