Kaal Sarp Dosha Calculator
Kaal Sarp Dosha (or Kaal Sarp Yoga) is said to form when all seven visible planets — Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn — lie on one side of the Rahu-Ketu axis in a birth chart. It is traditionally linked to repeated obstacles and delays, though many respected Jyotishis treat it as a minor condition rather than a severe dosha.
This free calculator builds your birth chart from your date, time and city, locates Rahu and Ketu, and checks whether every planet falls inside the 180-degree arc between them. It reports the verdict plus the houses Rahu and Ketu occupy, which define the type of the yoga.
How it is judged
| Condition | Result |
|---|---|
| All 7 planets between Rahu and Ketu | Kaal Sarp Yoga present |
| All 7 planets on the Ketu side | Kaal Sarp Yoga (reverse axis) |
| Planets on both sides of the axis | No dosha |
Important: Interpretations vary widely between traditions. Treat this as a computational check, not a diagnosis — consult a qualified Jyotishi before drawing conclusions.
Formula
For each planet: span = (planet longitude − Rahu longitude) mod 360. Dosha if all 7 planets have span ≤ 180 (inside arc) or all ≥ 180 (reverse axis).
Example
Rahu in Virgo, Ketu in Pisces. All planets between Virgo and Pisces moving forward → Kaal Sarp Yoga present.
