ResultMeaning
Not presentAt least one planet sits outside the Rahu–Ketu arc — no dosha
Partial (one planet barely outside)“Ardha” Kaal Sarp — much weaker, often ignored
Present — ascending (Rahu side)Udit-gola type; themes follow Rahu’s house
Present — descending (Ketu side)Anudit type; Ketu’s house colours the result
Present with strong Jupiter/lagna lordClassical mitigation — effects substantially reduced

Formula & methodology

Formula: Kaal Sarp = all seven classical planets contained in the half-zodiac arc from Rahu to Ketu (or Ketu to Rahu)

  1. Enter birth date, time and place.
  2. The calculator computes sidereal longitudes of the seven planets and the nodes.
  3. It checks whether every planet falls inside one of the two Rahu–Ketu arcs.
  4. If hemmed, Rahu’s house from the lagna names the type (Anant…Sheshnag).

Worked example — 1 Jan 1990, 06:00, Delhi: Rahu in Makara (3rd house), Ketu in Karka — but the Moon in Kumbha lies outside the hemming arc, so Kaal Sarp dosha is not present. One escaped planet is enough to break the formation.

Frequently asked questions

What is Kaal Sarp dosha?
A chart formation where all seven classical planets (Sun through Saturn) are confined to the arc between Rahu and Ketu — as if hemmed by the serpent’s head and tail. It is read as a karmic pattern of obstruction and delayed results in the houses involved.
Is Kaal Sarp in classical texts?
It is largely a later/medieval and modern-era construct — Parashara’s core texts do not define it. Many traditional astrologers therefore weigh it lightly, and several only consider it when other chart factors already point the same way. Treat it as a pattern, not a verdict.
What makes the dosha full vs partial?
Full: every planet strictly inside one node-to-node arc — checked by degree, not just sign. Partial (Ardha): a single planet, often the fast Moon, slips outside — which dissolves most of the formation’s force. Degree-level checking is exactly what this calculator does.
Which Kaal Sarp type is most discussed?
Anant (Rahu in the 1st) and Takshak (Rahu in the 7th) draw the most attention because they touch self and marriage. But each of the 12 types simply localises the Rahu–Ketu axis story in a house pair; the lagna lord’s strength moderates all of them.
What are the customary remedies?
Rahu–Ketu shanti and Kaal Sarp puja (Trimbakeshwar and Kalahasti are the famous venues), Nag Panchami worship, Maha Mrityunjaya japa and Saturday/eclipse-day charity. Families treat the rite as closure; astrologically, strengthening the lagna lord and Jupiter is the practical counterweight.
