Astrological transits are one of the main means used in horoscopic astrology to forecast future trends and developments (the other means used is astrological progression, which progresses the horoscope forward in time according to set methods). As its name implies, astrological transits involve a method of interpreting the ongoing movement of the planets as they "transit" the horoscope. This is most often done for the birth or Natal Chart of a particular individual. Particular attention is paid to changes of sign, or house, and to the aspects or angles the transiting planets make with the natal chart.
