The planetary return in astrology is when the transiting planet returns to the precise position it was in at the moment of a person's birth. Symbolically this means that the planet is beginning a new cycle in a person's life. Returns apply also to the sun and moon - an astrologer would say that a person's birthday is technically their 'solar return'; for it marks the day when the sun returns to the same position in the zodiac as on a person's original birthday. The most important returns are those of the outer planets Jupiter, Saturn and Uranus. Half-returns (when the planet reaches the halfway point in its journey) are also important, especially in the case of Uranus, as many people may not live long enough to see or get the full benefit of its full return of 84 years.
