Check Kaal Sarp dosh
How Kaal Sarp is checked
- Place Rahu and Ketu. Rahu is the mean lunar node; Ketu is exactly opposite, 180° away.
- Measure each planet from Rahu. Counting forward through the zodiac, a planet less than 180° after Rahu lies on the Rahu-to-Ketu side; more than 180°, on the Ketu-to-Rahu side.
- Count the seven planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn). All on one side is Kaal Sarp; six on one side is a partial pattern.
- Name the type from Rahu’s house counted from the lagna, which needs the birth time and place.
Worked example
17/07/2025, 06:00 IST, Nagpur. Rahu in Kumbha, Ketu in Simha.
| Graha | Position | Degrees after Rahu | Side |
|---|---|---|---|
| Sun | Karka 0° | 124° | Rahu → Ketu |
| Moon | Meena 17° | 20° | Rahu → Ketu |
| Mars | Simha 22° | 176° | Rahu → Ketu |
| Mercury | Karka 21° | 144° | Rahu → Ketu |
| Jupiter | Mithuna 14° | 107° | Rahu → Ketu |
| Venus | Vrishabha 19° | 83° | Rahu → Ketu |
| Saturn | Meena 7° | 11° | Rahu → Ketu |
Result: Kaal Sarp, all seven planets on the Rahu to Ketu side; type Karkotak (Rahu in the 8th house from the lagna).
Computed by the same engine as the calculator above.
Patterns like this one form for a few days or weeks at a time, when the slow planets and the nodes line up and the faster planets pass through the same half of the zodiac.
Reading the result
Kaal Sarp is a later idea that many classical texts do not mention, and astrologers give it very different weight. Its effect, where it is used, depends on the houses involved, the planets’ strength and the running dasha. See your whole chart in the Janam Kundli, and check the Manglik dosha too if you are matching for marriage. Rahu and Ketu also appear in the combinations commonly cited for pitra dosh.
Frequently asked questions
What is Kaal Sarp dosh?
A chart pattern in which all seven planets, from the Sun to Saturn, lie on one side of the axis between Rahu and Ketu, as if held between the head and tail of a serpent. When one planet is on the other side, it is often called partial.
Is Kaal Sarp in the classical texts?
Many classical texts do not mention it, and astrologers weigh it very differently. Where it is used, its effect is judged together with the rest of the chart and the running dasha, not on its own.
What are the 12 types?
They are named from Rahu’s house counted from the lagna: Anant (1st), Kulik (2nd), Vasuki (3rd), Shankhpal (4th), Padma (5th), Mahapadma (6th), Takshak (7th), Karkotak (8th), Shankhachud (9th), Ghatak (10th), Vishdhar (11th) and Sheshnag (12th).
Do I need my birth time?
Not for the check itself, which uses the planets’ positions; they change slowly enough that the date decides it on most days. The type needs the lagna, so it needs the time and place of birth.
Can Kaal Sarp dosh be remedied?
Families often perform a Kaal Sarp puja, but whether anything is needed depends on the whole chart. Namieta reads the chart and the dasha before suggesting any remedy.
Is my birth data stored?
No. The calculation runs in your browser and nothing you enter is sent to or stored on this website.
