What is the Equal Age Theory?
The Equal Age Theory purports that each of the 12 Great Ages last the same amount of time: about 2,160 years. This figure is based on 1/12th of the time for the precession of the equinox to make a complete cycle of about 26,000 years. This theory is in contrast with those who believe that great ages are irregular and that some great ages may last longer than others depending on the real estate they occupy along the ecliptic. For instance, Pisces takes up more room along the ecliptic than Aquarius, so some believe that the Age of Pisces should last hundreds of years longer than the Age of Aquarius. The Equal Age Theory takes into account three celestial planes: the plane of the ecliptic, the celestial equator and the galactic equator. If the great ages are divided by using these three planes as references, then each great age is of equal length.
