"House numbers are enough"
The enclosure depends on degrees around the node axis. This calculator uses exact zodiac longitudes.
Free Vedic astrology tool
Free Kaal Sarp Dosha calculator. Checks whether all seven planets sit on one side of the Rahu-Ketu axis, using exact degrees from your birth details.
Kaal Sarp Dosha (also written Kal Sarp Dosh) is a chart pattern where the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn all fall on one side of the Rahu-Ketu axis. This calculator checks their exact zodiac degrees, so it can catch cases that a simple house count misses.

How it works
The calculator builds a sidereal birth chart using your birth date, exact time and place. It measures each classical planet from Rahu around the zodiac and checks whether all seven fall strictly on the Rahu-to-Ketu side or all seven fall strictly on the other side. A planet exactly on a node boundary is not counted as enclosed. You can also view the planetary placements in your free Kundli birth chart.
| Step | Rule used on this page |
|---|---|
| Find the axis | Convert Rahu and Ketu signs and degrees to zodiac longitudes. |
| Place the planets | Measure the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn from Rahu. |
| Check both halves | All seven must lie strictly inside one of the two halves of the axis. |
| Handle a boundary | A planet exactly on either node is not treated as enclosed by this strict rule. |
Reading the result
Astrologers do not agree on the boundary rules, the cancellation rules or how to judge strength for Kaal Sarp Dosha. A positive axis check on its own cannot predict delays or difficulties. Read it together with the ascendant, planetary strength, aspects and the running dasha.
Rahu and Ketu are the two points where the Moon's path crosses the Sun's path, and they always sit exactly opposite each other. Together they split the zodiac into two halves. Kaal Sarp Dosha is said to exist when every one of the seven classical planets lies in the same half. Tradition pictures the planets as caught between the head (Rahu) and the tail (Ketu) of a serpent, which is where the name comes from.
Two planets can sit in the same house and still lie on different sides of the dividing line if one of them is close to a node. That is why this calculator uses each planet's sign and degree instead of the house number alone. Many free tools only count houses, and that is one reason their answers differ.
The tool first checks whether all seven classical planets lie strictly between Rahu and Ketu while moving forward through the zodiac. Then it checks the opposite half. It reports an indication if either complete enclosure is found. A single planet outside both halves is enough to prevent a positive result.
Traditional texts name twelve types, set by the house Rahu occupies: Anant (1st), Kulik (2nd), Vasuki (3rd), Shankhpal (4th), Padma (5th), Mahapadma (6th), Takshak (7th), Karkotak (8th), Shankhchud (9th), Ghatak (10th), Vishdhar (11th) and Sheshnag (12th). Each type is linked to a different area of life, so a puja or reading often starts with the type. This calculator reports whether the pattern is present, and it does not name the type.
Some traditions count a planet that sits on the node boundary. Some accept a partial enclosure with one planet outside. Some apply cancellation rules, for example when a planet sits very close to a node or the pattern is broken by a strong planet. This tool uses a strict all-seven rule and reports its result under that rule only. If another site says yes and this one says no, the likely cause is the rule, not an error.
Classical texts do not agree on this, and the idea of Kaal Sarp Dosha as a named affliction became popular mainly in more recent astrological writing. Many people with the pattern live ordinary, successful lives. Where astrologers see it as meaningful, they usually link it to delays, ups and downs, or a feeling of effort that gets less recognition than it should, and they say the effect depends on the whole chart and the running dasha. Treat it as one pattern to look at, not as a verdict.
Common practices include Shiva worship, chanting for Rahu and Ketu, offerings on Nag Panchami, and a Kaal Sarp puja at traditional sites such as Trimbakeshwar or Ujjain. These are matters of family custom and faith. Be wary of anyone who uses the result to frighten you into a costly ritual or a gemstone. A good practitioner will look at your whole chart first and will not demand a large payment.
Use a recorded birth time, check AM and PM, and pick the exact town from the suggestions. The Moon and the inner planets move quickly, so a time that is off by even an hour or two can move a planet across the dividing line. If you do not know your time, treat a positive or negative result as a rough indication only.
Clear answers
The enclosure depends on degrees around the node axis. This calculator uses exact zodiac longitudes.
This page uses a strict all-seven rule. Some traditions use a broader definition, which can produce a different answer.
One chart pattern cannot determine a life outcome. Planetary strength, aspects and dasha provide important context.
