There are four main types of astrology: (1) Genethlialogy is the creation of a birth chart that indicates an individual’s life course based on the position of the celestial bodies at the time of their birth; (2) General astrology relates the celestial moments, such as equinoxes, eclipses, or planetary conjunctions) to social groups, nations, or all of humanity; (3) Catarchic astrology determines the best times for commencing activities; (4) Interrogatory astrology involves a client asking an astrologer to answer questions based on celestial positions and movements.
