Magick exists in every culture, originating centuries ago, so that not all magickal practitioners subscribe to the same lunar cycles that the average Wiccan does. For instance, in some areas the full moon is considered the most effective time to cast any kind of ritual, whereas, others believe that the day the spell is performed (irrespective of the moon phase) is more relevant. Still others think that one can do any kind of spell at any time (just as you can pray at any time) and achieve just as potent results.
WAXING MOON: When the moon is on the increase, going from a small crescent to a full moon, from seven days after the new moon. Magick may be best done at sunset. For promoting development and improvement in many areas. Rituals involving love, sex, fertility, children, family, healing, education, good luck & wealth.
WANING MOON: When the moon is on the decrease, going from a full moon back to a crescent, or from seven days to ten days after the full moon. The waning moon rises at midnight and sets at noon. For ridding and shielding. Rituals involving exorcism, reversal, endings, banishing, purging, transformation, disease, stress, divorce, addictions, protection, et al.
