Astrology (from Greek: ast, ast (aster, astrós), "star", and (logos, logou),"word" or "speech") is a group of systems, traditions, and beliefs in which knowledge of the relative positions of celestial bodies and related detailsis held to be useful in understanding, interpreting, and organizing information about personality, human affairs,and other terrestrial matters. A practitionerof astrology is called an astrologer, or, less often, an astrologist. Numeroustraditions and applications employing astrological concepts have arisen sinceits earliest recorded beginnings in the 2nd millennium BCE. It has played a rolein the shaping of culture, early astronomy, andother disciplines throughout history.

Historically, astrology and astronomy were often indistinguishable, with the desire for predictive and divinatory knowledge one of the primary motivating factors for astronomical observation. Astronomy began to diverge from astrology after a long period of gradual separation in the 18th century, and has since distinguished itself as the scientific study of astronomical objects and phenomena, placing no significance on these phenomena's supposed astrological correlation.

Indian astrology also differs considerably from the Chinese horoscope which is based on the year of birth and believes that the year of birth indicates a certain phase or aspect of sixty year circle of time. Therefore you may find yourself born in the year of dog, horse or rat or even a dragon. Hence people who are born in a particular animal year share certain common traits just like people born in common zodiac do. Indian astrology is highly authentic and its predictions are believed to be the most accurate. Being based on the actual constellations of stars, this is the most widely used system of astrology across the world.
