There are a total of 12 zodiac signs. Each sign makes up 1/12 of the zodiac circle, meaning they cover 30 degrees each of the total 360 degrees. The 12 signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricorn, Aquarius, and Pisces. Each of these can be given to people born in certain periods of the year, and some people believe that they can be used to explain behaviors and predict the future. While this is up for debate, it is an interesting idea.
