Look at what phase the Moon was in on the day you were born. According to Dane Rudhyar's “Cycle of Lunations’, what distinguishes the natives of each phase.
The Moon is crucial for astrology because it is believed to symbolize affection, care, childhood needs, memories and the maternal or caregiver figure. The person born in the New Moon period has a lot of drive, innocence, desire. Those born on the crescent phase experience tensions, generally as a crisis between what is past and what is to come. The Lunatic is the oldest astrological energy in human beings (Ed. Uranus), astrologer Mimy Cirocco, cites the well-known “ cycle of lunations” in her book, “Lunatic’s Guide to Astrology”.
