Astrology compatibility provides a guideline on the relation of each zodiac sign with the other. Today the Western as well as the Chinese astrology is accepted all over the world and with that we have the western and the Chinese zodiac signs respectively. The western zodiac signs are based on the position and movement of the sun. For e.g., the house in which the sun is present at the time of the person's birth, becomes his zodiac sign. For e.g., the sun is present in Virgo between 23rd August to 23rd September. Therefore, those born in this period belong to the zodiac sign Virgo. On the other hand, according to the Chinese astrology, every year represents a specific zodiac sign and, hence, people born in that year have the same zodiac sign. In both, western as well as Chinese astrology, there are 12 zodiac sign which can be 'compatible' or 'incompatible' with each other. Also, some have 'mixed chances' meaning there are chances of having a good relationship, only if the partners try to find a middle way between two extremes. Chinese Zodiac Compatibility The 12 animal signs or Chinese zodiac signs include rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog, and pig. These animals are divided into 4 groups of 3 animals each. 1st group (rat, dragon, monkey); 2nd group (ox, snake, rooster); 3rd group (tiger, horse, dog); 4th group (rabbit, goat, pig).
