About this tool
Check if all 7 planets (Sun through Saturn) are positioned between Rahu and Ketu, forming Kaal Sarp Dosha. Identifies the dosha type — Anant, Kulik, Vasuki, Takshak, and 8 more — using real planetary positions.
The Kaal Sarp Dosha Checker computes sidereal positions for the Sun, Moon, Mars, Mercury, Venus, Jupiter and Saturn on a given birth date and reports whether all seven fall inside the 180-degree arc running from Rahu forward to Ketu — the condition Vedic astrology calls Kaal Sarp Dosha. When the condition is met it names the type from Rahu's sign, one of the twelve from Anant through Sheshnag. It is for anyone who has been told they have this yoga and wants to see the planetary longitudes the claim rests on rather than take it on trust.

Every planet is listed with its sidereal longitude, its rashi, its degree within that sign and its angular distance from Rahu.
A positive result is classified as Anant, Kulik, Vasuki, Shankhpal, Padmak, Mahapadmak, Takshak, Karkotak, Shankhchood, Ghatak, Vishdhar or Sheshnag.
Because each planet is flagged individually, you can see when six of seven fall in the arc — the near-miss that different astrologers read differently.
All seven classical grahas — Sun, Moon, Mars, Mercury, Venus, Jupiter and Saturn — must lie within the 180-degree half of the zodiac that runs from Rahu to Ketu. If even one planet sits on the other side of the Rahu-Ketu axis, the full yoga is not formed.
Birth time refines the result and is used here; birth place is not. Time matters most for the Moon, which moves roughly 13 degrees a day, so a chart where the Moon sits near the Rahu or Ketu point can flip with a few hours' difference — noon is assumed when you leave the time blank.
Sidereal, as Vedic astrology requires: tropical longitudes are computed first, then an ayanamsha correction is subtracted before the signs and the Rahu-Ketu test are applied. Rahu is taken as the Moon's mean north node, with Ketu exactly 180 degrees opposite.
No — it tests one specific condition and is informational only. Traditional interpretation weighs the ascendant, house placements, dashas and planetary strength alongside this yoga, so consult a qualified astrologer before drawing conclusions or acting on a result.
