Sade Sati is Saturn's slow passage over your natal Moon, lasting about seven and a half years. Enter your birth details above and you will see whether it is running for you now, which phase you are in, and the phases still to come. It is free and needs no account.
Everything depends on your moon sign. Sade Sati begins when Saturn enters the sign before it, continues as Saturn crosses your moon sign, and ends when Saturn leaves the sign after it. At about two and a half years per sign, that makes roughly seven and a half years.
Saturn takes about twenty nine years to go round the zodiac, so this returns about that often in a life. Saturn can also turn back into a sign it has just left, so a phase can show up as two separate stretches of dates.
Each phase has its own tone. None of them is a sentence, and many people look back on these years as the ones that made them more capable.
No. It is usually a period of more work and fewer shortcuts, and what you build during it tends to be solid. How it feels also depends on your dasha and on Saturn's role in your own chart.
Not usually. Sade Sati needs only your moon sign, and the Moon stays in one sign for over two days. Your time matters only if the Moon changed signs close to your birth.
If you are not in one now, the calculator shows when Saturn next reaches the sign before your Moon. If you are in one, it shows the phase you are in and the dates of those still ahead.
