Shani Sade Sati is the roughly seven and a half years when Saturn transits the 12th, 1st and 2nd from your moon sign. Check if it is running for you, which phase, and the approximate dates.
Sade Sati is judged from the moon sign, not the sun sign, which is why your birth time and place matter. Dates are approximate because Saturn slows and turns retrograde near sign boundaries. Saturn asks for patience and honest effort, it is not a sentence.
