An astrological age is a time period in astrologic theology which astrologers claim parallels major changes in the development of Earth's inhabitants, particularly relating to culture, society, and politics. There are twelve astrological ages corresponding to the twelve zodiacal signs in western astrology. Advocates believe that when one cycle of the twelve astrological ages is completed, another cycle of twelve ages begins.[1] The length of one cycle of twelve ages is 25,860 years.[2]
