Chinese Astrology is quite different from both Sidereal (vedic) and Tropical (Western) astrology. Here are three key features of Chinese Astrology that the readers should know so that they can appreciate the differences in the basis of predictions in these systems.
1. There is no casting of horoscope based on the time of an event in Chinese Astrology. Each zodiac sign in Chinese Astrology ( animal sign) is assigned to one of twelve “double-hour” periods of the day and to one of the twelve months in the year. Each zodiac sign is also assigned to a year and based on the five elements of the Chinese cosmology gives rise to a sixty year cycle. These twelve signs are the Rat, Ox, Tiger, Rabbit (cat), Dragon, Snake (Serpent), Horse, Sheep (Goat), Monkey, Cock, Dog, and Pig (Boar).
2. The twelve signs in Chinese Astrology derive not from the twelve months of the year. Unlike Hindu astrology or Western astrology, the twelve animal zodiac signs come from the twelve years of the Jupiter cycle (Jupiter takes approximately twelve years to complete one revolution around the sun)
3. Planetray motion has no importance on prediction in Chinese Astrology. Knowledge of exact motion of all planets like Saturn, Mars, Venus and lunar nodes etc.. is crucial to accurate prediction in Western and Vedic Astrology. In Chinese Astrology, no such planetary motion details is necessary for prediction.
