Sign Cusps
One additional influence that is important is the cross-influence between the zodiac signs near the borders that separate them. These are known as cusps - the transition zone where the Sun is moving from one sign to the next.
If, for example, you were born on November 20, the Sun was in Scorpio (according to tropical astrology), giving you the sensitive and emotional qualities of a water sign. However, the active and fiery but emotionally repressed Sagittarius being just days away will give the Scorpio native a unique flavor.
Generally people born on the cusp between two zodiac signs have qualities found in both signs or a blend of traits in their nature. The cross-influence is apparent during the last few days of the departing sign and the first few days of the new sign. While the new sign is gaining its ascendancy the influences of the old will persist, but it will gradually lose its hold after about a week and then the new sign will be in complete control.
People with the “classical” or “pure” influences of a sign are therefore the ones born within the middle two weeks of the sign. For our example Scorpio, that would roughly be November 1-15.
