A zodiac, or astrological, sign is a classification that describes a 30 degree span of the path of the sun around the celestial sphere. The signs include Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.
The signs often correspond with a person's birthday, as each of the 12 signs represent a certain date range. Zodiac signs were first created by the Babylonians in the 3rd millennium B.C. They were used to help astrologers dictate where the sun was in the sky, and the patterns of the stars, as well as other celestial bodies. Many people believe that their zodiac sign, relative to their birthday, corresponds to a specific fortune, and they will read horoscopes that are supposed to predict their futures and reveal aspects of their personalities.
