Frequently asked questions
What is a sun sign?
Your sun sign is the zodiac sign the Sun occupied when you were born. It represents your core self, ego, and the central themes of your identity — the part of astrology most people already know.
I was born on a cusp — which sign am I really?
There is no such thing as being "both" signs. On cusp dates the Sun is in one specific sign, which depends on your exact birth year, date, and even time. This calculator uses the real position of the Sun to remove the guesswork.
Is my sun sign the same as my star sign or zodiac sign?
Yes. "Sun sign," "star sign," and "zodiac sign" all refer to the same thing — the sign the Sun was in at your birth, which is what newspaper horoscopes are based on.
