Kaal Sarp Dosh Calculator

Checking Kaal Sarp Dosh From Your Birth Chart

Kaal Sarp Dosh is a specific, well-defined planetary geometry: all seven classical grahas falling on one side of the Rahu-Ketu axis, the two lunar nodes that sit exactly 180 degrees apart in every chart. It is a precise condition, not a catch-all explanation for difficulty in life, and plenty of people carry the combination without it dominating their chart reading. This calculator checks the actual degree-by-degree position of every planet against Rahu and Ketu, rather than estimating from a rough chart.

How the Calculator Works

1. Enter your date, time, and place of birth. All three are needed for this check.
2. The calculator computes the exact longitude of Rahu and Ketu at your birth, along with the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn.
3. It traces the arc from Ketu to Rahu, moving in Rahu's direction of travel, and checks whether every one of the seven classical planets falls within that arc.
4. If the full formation is present, it identifies which house Rahu occupies to name the specific classical type.

Birth time is essential here, more so than for most other checks. Kaal Sarp Dosh depends on the exact degree of each planet relative to the node axis, and even a small shift in birth time can move a borderline planet from just inside the arc to just outside it, which changes the result from "present" to "not applicable." If your birth time is only approximate, treat a borderline result with some caution.

What the Calculator Checks

The determination is entirely geometric: do all seven classical planets sit within one continuous arc between Ketu and Rahu, with none crossing to the other side? If even one planet falls outside that arc, the full formation does not apply, regardless of how tightly the other six are clustered.

When the formation is present, classical tradition names it after the house Rahu occupies at birth, with Ketu automatically in the opposite house. The twelve traditional types, Anant, Kulik, Vasuki, Shankhpal, Padma, Mahapadma, Takshak, Karkotak, Shankhachud, Ghatak, Vishdhar, and Shesh, each carry a classical association with a different area of life, but these are described as areas of focus rather than fixed outcomes. The calculator also checks for recognised cancellation and mitigating factors, such as a planet sitting just outside the arc, or supportive influences on Rahu and Ketu from elsewhere in the chart, and lists these when relevant.

Reading Your Result

The result will show one of a few outcomes:

• A named type (for example, Anant or Shankhachud): the full formation is present, and Rahu's house placement determines which of the twelve classical types applies.
• Cancelled or partial: most but not all planets fall within the arc, or a recognised cancellation factor applies, so classical texts treat the combination as significantly weaker than a full formation.
• Not applicable: the planets are spread across both sides of the node axis, and the formation does not apply.

Whichever result you get, it is one structural feature of a chart among many. Classical texts describe it as concentrating attention around the Rahu-Ketu axis, especially during Rahu or Ketu's own planetary period, not as a guarantee of misfortune on its own. The overall strength of the chart, the dignity of the enclosed planets, and the current Dasha matter just as much as the presence of the combination itself.
