In astrology, the Solar Age is identified with the sign (or "house") of the zodiac that contains the Sun at the moment of the vernal equinox. This location describes a slow apparent circle through the sky due to precession of the equinoxes, with each age lasting one-twelfth of the complete rotation, or approximately 2,100 years. The current Age of Pisces, which began around the time of Christ, depending on where along the Ecliptic the division between the Constellations of Aquarius and Pisces is set, is due to end around AD 2100, when the apparent point of vernal equinox precedes across the dividing line into the constellation Aquarius. The Age of Pisces will be replaced by the Age of Aquarius.
