Sāḍhe Sātī (also written Saade Saati) is the 7.5-year period during which Saturn transits through three consecutive signs: the sign 12th from the Moon sign, the Moon sign itself, and the sign 2nd from the Moon sign. Saturn takes approximately 2.5 years to transit each sign, so the total period is 7.5 years. Classical texts warn this period brings hardship, tests, and transformation — but also maturity, discipline, and karmic resolution. The degree of difficulty depends on Saturn's strength and placement in the natal chart. Sade Sati typically occurs 2-3 times in a lifetime.
