Well, if you follow the moon phases, the waxing moon is indeed perfect for doing a love spell. You should do it now.
For the full moon, it is a powerful energy for rituals of prophecy, divination and protection. Any spellwork that requires extra energy, such as finding a new job or healing serious conditions, is best begun during the full moon. The full moon is also for love, gaining sacred knowledge, legal matters, attracting money and prophetic dreams.
