- Age of Aquarius (Wikipedia)
The Age of Aquarius, in astrology, is either the current or forthcoming astrological age, depending on the method of calculation. Astrologers maintain that an astrological age is a product of the Earth’s slow precessional rotation and lasts for 2,160 years, on average (one Great Year equals 25,920-year period of precession / 12 zodiac signs = 2,160 years).
