what year did the age of aquarius begin
Age of Aquarius The approximate 2,150 years for each age corresponds to the average time it takes for the vernal equinox to move from one constellation of the zodiac into the next. This can be computed by dividing the earth's 25,800-year gyroscopic precession period by twelve, the number of zodiac constellations used by astrologers. According to different astrologers' calculations, approximate dates for entering the Age of Aquarius range from AD 1447 (Terry MacKinnell) to AD 3597 (John Addey).[2]
