Kaal Sarp Dosh, also called Kaal Sarp Yoga, forms when all seven main planets — the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn — are hemmed in on one side of the Rahu-Ketu axis. Rahu is the head of the celestial serpent and Ketu its tail, and when every planet falls between them the chart is said to be caught in the coils of the serpent. This can bring sudden ups and downs, delays, struggle and a feeling of unseen obstacles — but it can also give great drive, ambition and eventual success, especially in later life. There are twelve named types of Kaal Sarp Yoga depending on which houses Rahu and Ketu occupy. This calculator checks every planet against the Rahu-Ketu arc, tells you whether the dosh is present, its type, and the traditional remedies.

Your date, exact time and place of birth — the Rahu-Ketu axis and planet houses depend on your precise chart.
Using the Swiss Ephemeris we test whether all planets fall on one side of the Rahu-Ketu axis.

Few terms in Vedic astrology cause as much fear as Kaal Sarp Yoga — and few are as exaggerated. The truth is more balanced. Kaal Sarp forms only when every one of the seven main planets is trapped on one side of the Rahu-Ketu axis; if even one planet sits outside, the dosh is only partial and much weaker. Even a full Kaal Sarp Yoga is not a curse: it typically brings a slower, harder early life followed by strong, self-made success, because the same intense energy that creates obstacles also creates ambition and resilience. Many well-known achievers have this yoga. Knowing your true status — full, partial or absent — replaces fear with clarity.
A harder early life with sudden ups and downs and obstacles.

If your chart shows a genuine, full Kaal Sarp Yoga, traditional remedies can bring relief. The most powerful is devotion to Lord Shiva — reciting the Maha Mrityunjaya mantra, offering water on a Shivling, and observing Mondays. A Kaal Sarp Dosh Nivaran puja, often performed at Trimbakeshwar near Nashik, is widely recommended. Offering to Nag Devta (the serpent deity) on Nag Panchami, and keeping a peacock feather, are also traditional. As always, remedies work best alongside a proper reading — and a partial or absent dosh needs no fear at all.
