What Kaal Sarp Dosha actually is
Kaal Sarp Dosha forms when all seven planets — Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn — fall on one side of the Rahu-Ketu axis, so the entire chart is "swallowed" between the two lunar nodes. Rahu is the serpent's head, Ketu its tail; when every planet sits within that half-circle, the yoga is complete.
Full vs partial
If even one planet falls outside the Rahu-Ketu arc, the dosha is partial (bhanga) — much milder, and often effectively cancelled. This tool tells you whether your chart is full or partial and names the planet that breaks it, so you get an honest picture instead of a scare.
The twelve types
When birth time is known, the yoga is classified into twelve types by the house Rahu occupies — Anant, Kulik, Vasuki, Shankhpal, Padma, Mahapadma, Takshak, Karkotak, Shankhachur, Ghatak, Vishdhar and Sheshnag. The type indicates the area of life most touched, which is why Rahu's house — not just the presence of the yoga — matters.
Is it as bad as the internet says? No.
Kaal Sarp is the most over-dramatised yoga online. Many highly accomplished people carry it; it often reads as a life of sustained effort rewarded by delayed but real success. Its true weight depends on the rest of the chart, the running dasha, and whether it is full or partial. A grounded reading — not a frightening label — is what tells you what it means for you.

How this is calculated
Planet positions are computed in your browser with astronomical formulas that are checked every night against the Swiss Ephemeris, the standard used by professional astrology software. Sidereal positions use the Lahiri (Chitrapaksha) ayanamsa, the standard ayanamsa of Indian panchangs, and the birth time is converted from your city's own time zone. Method reviewed by Dr. R.P. Sharma, Ph.D. and Acharya in Phalit Jyotish, practising Vedic astrology since 1979.
Last verified: 28 September 2026, against the Swiss Ephemeris and the nightly tool test.
Frequently asked questions
Do I have Kaal Sarp dosh in my kundli?
Enter your birth details above. The tool checks whether all seven planets fall on one side of the Rahu–Ketu axis and, with a birth time, names the type by Rahu’s house — free.
Is partial Kaal Sarp also a dosha?
When even one planet stands outside the Rahu–Ketu arc, the yoga does not fully form. The tool reports it as partial and names the planet that breaks it; a partial yoga is much milder and often treated as cancelled.
What are the 12 types of Kaal Sarp dosha?
They are named by the house Rahu occupies: Anant (1st), Kulik (2nd), Vasuki (3rd), Shankhpal (4th), Padma (5th), Mahapadma (6th), Takshak (7th), Karkotak (8th), Shankhachur (9th), Ghatak (10th), Vishdhar (11th) and Sheshnag (12th).
Is Kaal Sarp dosha in the classical texts?
No. The major classical texts such as Brihat Parashara Hora Shastra do not describe it; it belongs to a later tradition. That is one more reason to read it against the whole chart rather than treat it as a verdict.
Does Kaal Sarp dosha always need a puja?
No. Whether any remedy is needed depends on the rest of the chart and the running dasha. Simple traditional observances are Rahu and Ketu mantras and worship of Lord Shiva; a formal puja is advised only when the chart calls for it.
Is this calculator free?
Completely — no signup or login, and it runs in your browser on the same Lahiri sidereal engine as the site’s full free kundli.
From the calculator to the chart
Knowing Kaal Sarp forms is the first step; knowing what it actually means for your life is the reading. For the type, whether it is truly full, the dasha timing and remedies that fit, consult Dr. R.P. Sharma (practising since 1979) online anywhere at a flat, all-inclusive fee of ₹5,100.
This tool computes correctly, but it cannot weigh what it finds against the rest of your chart — that is what a reading does. Dr. R.P. Sharma reads every chart personally, practising since 1979.
