Is moon sign astrology is correct or sun sign astrology is correct?

While the Moon sign and Sun sign can be important, to get the most out of Astrology you're going to need to have your whole birth chart interpreted. The Sun and Moon are just two points out of several that an astrologer would consider.

People may feel more like their Moon sign if their Moon is more prominently placed in their horoscope or what time of the day they were born, but neither Sun or Moon signs are more correct or accurate than the other.
