The positions of the zodiac signs remain fixed in these 12 houses, while the planets move through the signs over the course of months or years. The ‘houses’ of a birth chart are a series of twelve sectors or divisions of the plane of the ecliptic, which represents the sun's celestial path for a year.
There are twelve zodiac signs, represented by figures of animals. The zodiac is a zone or a belt in space through which the planets move. Also called the natal chart, it holds the key to understanding yourself on physical, mental, emotional and spiritual levels. A birth chart is a unique karmic map that presents an opportunity for a person to know about his or her past and present, and delve into the future.
