In astrology, Astrological Timing refers to methods used to examine how planetary cycles and changing chart relationships correspond with periods of development, emphasis, transition, or shifting circumstances. Timing techniques may include transits, progressions, returns, profections, solar arcs, and other systems that compare a natal chart with later planetary or calculated positions. Different astrological traditions use these methods in different ways. Astrological timing may be approached reflectively as a way of exploring themes and developmental periods rather than as a means of guaranteeing specific events or outcomes.
