Shani and the seven and a half year cycle
Saturn takes roughly two and a half years to cross a sign and about twenty-nine and a half years to complete one full cycle. Its transit drives the most widely observed period in Indian astrology, Sade Sati, which runs from the sign before the birth Moon sign through the Moon sign itself and into the sign after it.
Retrograde dips and repeated signs
Saturn appears to reverse direction for roughly four and a half months each year before moving on, and during that retrograde dip it can step back into the sign it has just left. This is why a sign can appear twice on a single Saturn calendar. It is one continuous cycle, not two.
What Saturn rules
Saturn is the karaka for time, labour, structure, hardship, longevity and service. It is exalted in Libra and owns Capricorn and Aquarius. Its transit is read against the houses from your Moon sign, and the houses it aspects are central to the classic interpretation.
Saturn transit questions
How long does Saturn stay in one sign?
About two and a half years, which is why Sade Sati spans roughly seven and a half years in total. For the full phase-by-phase Sade Sati breakdown with the birth Moon sign matrix, see the dedicated Sade Sati page.
Why does Saturn appear in the same sign twice?
Because Saturn turns retrograde during the year and briefly steps back into the sign it left a few weeks earlier before moving forward again. It is a single continuous period, not a second visit.
Does Saturn affect everyone the same way?
No. The natal Saturn placement, the strength of the Moon, the running Dasha and the houses involved all change how the same transit is experienced. Use these dates as a calendar and the birth chart for interpretation.
Are these transit dates the same for every city?
Yes. The instant a body changes sign is an astronomical fact, not a local one, so the underlying UTC date is identical everywhere on Earth. This page converts those instants to your selected city for display, so changing your location changes the clock time you see but never the date, and never triggers a new calculation.
