In Tibet, astrology is considered to be one of the five traditional sciences. Tibetan Astrology originated around 1000 years ago and it has its roots in several other traditions: Indian, Chinese, Buddhism and even the local Bon religion. This form of astrology can broadly be divided into two parts: the "Naktsi" and the "Kartsi" astrology. The "Naktsi" astrology has its origin in Chinese astrology; whereas the "Kartsi" astrology has its origin in Indian or Western astrology. Tibetan astrology is a combination of the Western and the Chinese Astrology. As such, the twelve Sun Signs of the Tibetan Astrology are similar to that of the twelve zodiac signs of the Western Astrology; while the twelve Tibetan Animal Signs resemble the Chinese zodiac.
