An astrological age is a time period in astrology which is believed by some to parallel major changes in the Earth's inhabitants' development. It roughly corresponds to the time taken for the vernal equinox to move through one of the twelve constellations of the zodiac. The Ages in astrology, however, do not correspond to the actual constellation boundaries where the vernal equinox may be occurring in a given time.
