More than 3000 years ago, astronomers wondered how the sky would appear if the stars could be seen during the daytime. Based on their observations of the night sky, some astronomers determined that during the daytime, the Sun would appear to "enter" or pass through a different constellation each month. These twelve constellations are called the Zodiac.
Many ancient people believed that a person's behavior, emotions, and fate were heavily influenced by the month of that person's birth--ie. that person's astrological sign. Even today, thousands of years later, some people still believe in the powers of the zodiac and read their horoscopes for daily guidance.
Some say that astrology is the language of the sky. And in a way it is! It's full of calculations, symbols, hieroglyphics, and mystery. It can be exciting and confusing.
But it's like any other language, once you begin to learn and use it, how it works starts to make sense.
