Sade Sati is based on your natal Moon, so an accurate birth time matters. Your birth details are used only to calculate — nothing is saved, and no account is needed.

What Sade Sati really is

Sade Sati is the roughly seven-and-a-half-year stretch when Saturn moves through the sign just before your natal Moon, then your Moon sign itself, then the sign just after. It has a fearsome reputation — but stripped of the dread, it’s simpler than that: a long Saturn lesson in responsibility, patience, and getting real.

Saturn doesn’t punish; it removes what was never solid and rewards what is. Plenty of people look back on their Sade Sati as the years they finally grew up. Demanding — yes. Doomed — no.

The three phases

  • Rising — Saturn in the 12th from your Moon. The slowing-down begins; endings, withdrawal, quiet pressure.
  • Peak — Saturn over your Moon. The core test: emotional weight, responsibility, the real work.
  • Setting — Saturn in the 2nd from your Moon. Releasing what has matured; often family, security, resources.

How it’s calculated

It’s based on your natal Moon signand where Saturn is transiting now. The calculator finds your Moon sign from your birth details, checks Saturn’s current sign, and reports the phase and approximate dates. (Dates are computed from Saturn’s motion and are accurate to about ±2 weeks around sign changes — cross-check an ephemeris for exact timing.)

Frequently asked questions

What is Sade Sati?

Sade Sati is the roughly 7.5-year period when Saturn transits the sign before your natal Moon, your Moon sign itself, and the sign after it. It's a Saturn 'maturation' phase associated with slowing down, added responsibility, and getting real about your life — not the guaranteed misfortune it's often portrayed as.

How is Sade Sati calculated?

Find your natal Moon sign, then look at where Saturn is transiting now. When Saturn is in the 12th from your Moon, the cycle is rising; over your Moon sign, it's at peak; in the 2nd from your Moon, it's setting. The calculator checks Saturn's current position against your Moon and tells you the phase and approximate dates.

What are the three phases of Sade Sati?

Rising (Saturn in the 12th from the Moon) — the slowing-down begins, often around endings and inner pressure. Peak (Saturn over the Moon) — the core test of responsibility and emotional weight. Setting (Saturn in the 2nd from the Moon) — releasing what has matured, often around family and resources.

Is Sade Sati always bad?

No. Sade Sati is demanding, not doomed. Saturn rewards honesty, patience, and doing the real work; it removes what was never solid. Many people point to their Sade Sati as the period they grew up the most. How it actually lands depends on where it falls in your chart and how strong Saturn and the Moon are.

What are Ashtama Sani and Ardha Ashtama?

These are related Saturn-over-Moon transits the calculator also flags: Ashtama Sani is Saturn in the 8th from your Moon, and Ardha Ashtama ('half Sade Sati') is Saturn in the 4th. Both are considered sensitive Saturn periods, though shorter than Sade Sati.
