There are twelve signs in the Zodiac, one for each month of the year. Unfortunately, the signs and the calendar don’t align perfectly. The Zodiac begins in mid-March, not on January first; and signs span from roughly the 20th or 21st of one month to the 19th or 20th of the next, not the 1st to the 31st. (Are you confused yet? No? Good!)
When someone asks you what your sign is, they’re referring to your Sun Sign -- where the sun was in the Zodiac at the exact moment of your birth. But every other planet in your birth chart is also located in a particular sign, and is influenced by that sign’s unique energy.
This explains why everyone who’s born under the influence of the same Sun Sign can still have such vastly different personalities; each of us is made up of a complex and unique combination of influences from the twelve signs, the twelve houses and all the planets, asteroids and points... Now, that’s definitely getting complicated! But clearly, having lots of planets in a certain sign in your chart will only intensify that sign’s influence in your life.
Each sign of the Zodiac is associated with a particular symbol, usually an animal, like the Ram (Aries) or the Bull (Taurus); an element, such as Air (Gemini) or Water (Cancer); and a quality, such as Fixed (Leo) or Mutable (Virgo). Each of these variables helps us to understand more about the signs that influence us and the energy inherent in each.
The signs of the zodiac are: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces
