What it does

Shows when Saturn's 7½-year passage around your Moon sign (Sade Sati) began or will begin, its three phases, whether you are in it now, and any Shani Dhaiya periods.

Why it matters

Sade Sati is feared in popular culture. Seeing the actual dates, phases and the calm traditional reading takes the mystery out of it.

How it is worked out

  1. Take your Moon sign.
  2. Track Saturn's sidereal sign over time (sampled every 6 days).
  3. Sade Sati is the run of Saturn in the 12th, 1st and 2nd signs from your Moon sign; the tool lists each contiguous period with its phase.

How to read your result

  • The timeline graph: bands for each phase and a marker for today. Hover or tap a band for exact dates.
  • Active phase: rising, peak or setting, or none.

What it cannot tell you

Saturn can re-enter a sign during a retrograde, so boundary dates are approximate to the 6-day sampling. The tool states that no controlled evidence shows Sade Sati changes outcomes.
