Frequently asked questions
What is a sun sign?
Your sun sign is your main zodiac sign, decided by the position of the Sun on your birthday. It is the sign most horoscopes refer to and describes your core identity, ego and the way you shine.
What if I was born on the cusp?
If your birthday falls on the day the Sun changes signs, your sun sign can depend on the exact year and time. If your result feels borderline, check your full birth chart for certainty.
Sun sign, moon sign and rising sign, what is the difference?
Your sun sign is your core self, your moon sign your emotions, and your rising sign your outward style. Together they are your Big Three, the foundation of your chart.
