The 12 Zodiac Cusps
Born between two signs? Find your cusp, its dates and blended personality below — and confirm your true sun sign.
What does it mean to be “on the cusp”?
If your birthday falls in the two or three days where one zodiac sign transitions into the next, you're said to be born on the cusp. Cusp astrology blends the traits of both neighbouring signs into a single personality — and many people born here feel they don't fully belong to either sign alone.
Worth knowing: astrologically, the Sun is always in exactly one sign, so you do have one true sun sign. But because the boundary shifts slightly each year, only an exact calculation confirms which one you are.
Frequently asked questions
What is a zodiac cusp?
A cusp is the boundary between two zodiac signs. If you're born in the few days where one sign ends and the next begins, you're said to be 'on the cusp' and may share traits of both signs.
Are cusp signs real in astrology?
Not officially — at any moment the Sun is in exactly one sign, so you have a single sun sign. But sign-change dates shift slightly each year, so people born near a boundary may genuinely be either sign, which is why cusp lore is so popular.
How do I find out my real sign if I'm on the cusp?
Use a sun sign calculator with your exact birth year. Because the Sun enters each sign on a slightly different date annually, only an exact calculation confirms your true sun sign.
