OK what is a sun sign and a moon sing? and how do you figure which ones which? I am January 31 and I always thought aquarius...but I didnt know there were son and moon sings!!!
Your sun sign (aka, your star sign) is the sign in which the sun was when you were born - the sun was in Aquarius on January 31.
Your moon sign is the sign in which the moon was when you were born. The moon changes signs more frequently than the sun, so this would depend on your time and place of birth.
Donna, or someone with more knowledge of this, would have to jump in now to explain what effect the position of the moon has on your personality and horoscope. All I remember is that it slightly modifies your star sign attributes.
