the waxing Moon is the best time to do a spell for growth, beginning new projects, initiation and enhancement.
during the waning Moon, do spells to banish evil influences, lessen or remove obstacles and illness, neutralize enemies, and to remove harm.
three days after the New Moon are the most powerful times to work spells for growth and beginnings which should manifest at the Full Moon
the days just before the Full Moon are the most powerful times for fruition and completion. Remember that even though the Moon looks Full Moon in the sky for two or three nights, it is only EXACT at the time posted on your calendar. Anything after that time is a waning influence. Do your Full Moon spell before the exact time listed.
