Sade Sati is the seven-and-a-half year period when Saturn transits the three signs centred on your natal Moon: the sign before it, the Moon sign itself, and the sign after. Because the Moon governs the mind and emotions in Vedic astrology, this transit is felt inwardly — as pressure, seriousness, and a stripping away of what was never solid.
It unfolds in three phases of roughly two and a half years. The rising phase (Saturn in the 12th from the Moon) often touches finances, sleep, and hidden matters. The peak phase (Saturn over the Moon) presses most directly on emotional life and identity. The setting phase (Saturn in the 2nd from the Moon) tends to concern family, speech, and resources. Each asks for maturity in a different area.
Sade Sati is not a curse. It is Saturn's long lesson in responsibility and realism, and those who meet it honestly usually come out steadier and clearer. This calculator tells you whether it is currently active and which phase you are in; your full chart maps the exact start and end windows.
