Kaal Sarp Dosha is used in some Jyotish practice for a chart pattern in which the seven classical planets fall on one side of the Rahu–Ketu axis. Before discussing its interpretation, specify the actual rule. Practitioners may differ about planets on the axis, which direction to count, and what constitutes a partial pattern.
What inputs are needed?
You need longitudes for the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn, plus Rahu and Ketu, using consistent settings. State whether the node positions are mean or true nodes. Do not mix a node position from one chart with planets from another date or zodiac convention.
AstroMystra does not currently compute Rahu/Ketu longitudes. Its dasha tables use their names as period rulers, which is not a calculation of their chart positions. This article explains a manual geometric test; it is not an automated Kaal Sarp diagnosis from this site's calculator.
Worked example with fictional positions
Place Rahu at 40° and Ketu at 220°. The axis splits the circle into two arcs of 180°. For this example only, count positions strictly inside an arc; a planet exactly on an endpoint is a boundary case.
- Suppose the seven planet longitudes are 60°, 80°, 100°, 120°, 150°, 180°, and 200°.
- Each lies strictly between 40° and 220°: all seven are enclosed under the stated rule.
- Move one planet to 250°. Now planets occupy both sides of the axis, so the same rule fails.
For an arc crossing 0°, subtract the starting node's longitude from each planet, then add 360° if the result is negative. An offset strictly between 0° and 180° is inside the forward arc. This avoids mistaking a position near 0° for being outside an arc simply because its printed number is smaller.
Boundaries and disagreements
A planet at 40° or 220° in this example is on the axis. Do not quietly count it as enclosed while another calculator excludes it. Rounded displays can conceal such a case. Document the raw positions, node convention, endpoint rule, and any additional conditions before comparing results.
Named subtypes based on house placement add another dependency: reliable birth time and an explicit house system. A list of subtype names does not establish either the calculation or its predictive value.
Interpretation and provenance
This guide does not claim a verified ancient origin or a particular century of invention for the named classification. A statement about its history requires a traceable textual edition or historical source; a general reference to classical texts is insufficient. The example above establishes only enclosure under one stated rule.
The pattern does not establish that someone will suffer illness, failed relationships, blocked progress, or shortened life. Nor does finding it establish a need for paid rituals or gemstones. Base decisions on actual circumstances and appropriate professional advice.
