When it comes to Moon Magick, the possibilities are endless. Working with the natural rhythm of the moon's cycles is without a doubt, magically beneficial. It's only a matter of knowing how and when.
You can start by purchasing an astrological calendar or a Magical Witches' Almanac to keep up with the moon phases; they can be found in the New Age section of almost any large bookstore and are fairly inexpensive. Now a days you can also find this information quite easily online.
Here is some basic information to get you started...
New Moon: The new moon is for starting new ventures, new beginnings, new love, romance, health or new job. New Moon workings can be done from the day of the new moon to three-and-a-half days after.
Waxing Moon: The waxing moon is for constructive magic, such as love, wealth, success, courage, friendship, luck or health. Waxing moon workings can be done from seven to fourteen days after the new moon.
Full Moon: Prime time for rituals for prophecy, protection, divination. Any working that needs extra power, such as help finding a new job or healing for serious conditions, can be done now. Full Moon magick can be done from fourteen to seventeen-and-a-half days after the new moon.
Waning Moon: The waning moon is used for banishing magic, for ridding oneself of addictions, illness or negativity. Waning Moon magick can be done from three-and-a-half to ten-and-a-half days after the full moon.
Dark Moon: The dark moon is a time for dealing with attackers, for exploring our darkest recesses and understanding our angers and passions, as well as bringing justice to bear. Dark Moon magick can be done from ten-and-a-half to fourteen days after the full moon.
