Is your date of birth on a cusp?
If you were born on the first or last day of a Sun sign, in astrological terms you were born on a cusp. If that's the case, you will probably benefit from reading your own Sun sign and the Sun sign that ends or begins right before or after your date of birth. For example, if your birth date is 22 December, your Sun sign is Capricorn, but you probably have some Sagittarian traits as well.
The above dates are a guideline only. Because of leap years, time zone differences and other factors, the exact day and time when the Sun changes signs varies from year to year. If you are born close to the changeover dates (close to the cusp) of the signs, you need to have your own personal horoscope
drawn up in order to know exactly which astrology sign you were born under.
