The 12 signs of the zodiac have specific influences, and when the moon is in each sign, lends a different influence to it. This helps us to more clearly narrow our chances of doing our rituals at the right time. If you follow the moon and catch her in the correct phase whilst being in the correct sign, your rituals will have much more power, and are more likely to work.
M oon In . . . . Aries    (key words - protection, courage) Aries is a good time for new ventures particually if they are financial, medical, or related to construction. Because Aries is a fire sign it is energetic, good for working magick for personal strength and stamina.
Taurus   (key words - peace, money, growth) Taurus is a good time for magick where issues of trust and loyalty are at stake, and it can give a boost of determination to see you through to the end of any endeavour. Passions can run high during this transit and spells to increase one's sensual nature are at their best. One warning, however: spells begun with the moon in stubborn Taurus maybe hard to shut down once they are underway.
Gemini   (key words - divination, study, wishes) Gemini is a good is an excellent time for any type of spells concerning communication, writing, mass media, or for ferriting out one's hidden enemies. Healing spells also work very well during moon in Gemini.

Leo   (key words - sex, passion) Moon in Leo is a good time for working magick on behalf of others. This is also a fine transit for working spells for leaders, for the same use of power, and for binding spells.
Virgo   (key words - healing) When the moon is in Virgo it is a good time to work with matters pertaining to education, volunterrism, and health. It is a also a prime time for casting spells requring great attention to detail, as this is the province of Virgo.
Libra   (key words - marriage, partnerships) While the moon is in Libra it is a good time for couples magick, and for all spells for peace and balance, or for the promotion of fairness and justice. Venus rules romance and this is a excellent transit for love magick. Spells requiring, or aligned with, diplomancy and adaptability also work well here.
Scorpio   (key words - courage, defense) Scorpio is the keeper of secrets, and so with the moon here we find it is a good time to try and unlock occult wisdom through divination and ritual. As it is a very fertile sign it is good time to work on fertility and sex magick. Matters pertaining to deceit, trustworthiness, and things hidden are best dealt with now. Scorpio is the sign of ambition, and spells for personal promotion work well at this time. This transit is very compatible with almost all lunar spellwork.
Sagittarius   (key words - travel) Moon in Sagittarius is the sign of the non-conformist, an excellent time to experiment with new spells and ritual methods. Because of its optimistic nature, challenges are often accepted during this transit, making it a good time to work magick for the more elusive things in your life.
Capricorn   (key words - banishment) While the moon is in stable Capricorn, it is the time for dealing with material concerns, such as magick for obtaining a much needed item. It is also a transit when pessimism and despondency tend to come to the forefront. If you are prone to depression, avoid divination during this transit and instead work spells for a better mental attitude.
Aquarius   (key words - secrets, mysteries) Moon in Aquarius is a good time for troubled covens to meet. Magick for world peace and understanding are best undertaken in this sign. Warning…. Because this sign is outwardly fighting for its identity in this New Age, anything can happen in your Aquarian Moon Magick.
Pisces   (key words - psychich awareness, dreams) Pisces is a highly psychic sign and is a good time to try that divination method which has always eluded you. The two fish which symbolize the sign point not merely in two different directions, but the upper and lower worlds, and the inner and outer realms, offering us a bridge between them. Not a good time for protection spells, but is a good time for dream work, astral projection, guided meditations, and is highly compatible with all lunar spellwork.
