Your Sun sign is the sign of the zodiac where the Sun was at the time you were born. In astrology, it makes up one-third of your primal triad. In your natal chart, the Sun represents your personality and countenance. This is why more importance is placed on it than on the other planets and features, and why your daily horoscope is written for your Sun sign. There are 12 signs of the zodiac, each one with its own attributes and qualities. Since the Sun is in a particular sign when you were born, your personality will reflect many of that sign's traits.
