What Is Cusp in Astrology?

If you're born near the date when the Sun moves from one sign to the next, you're said to be 'on the cusp.' For example, someone born on April 19th might identify with both Aries and Taurus traits. While traditional astrology says you're definitively one sign or the other (based on the Sun's exact position at your birth time), many people born on cusps feel they embody qualities of both signs. Getting your exact birth chart calculated settles the question definitively.
