As per Vedic astrology Kala Sarpa Yoga is an inauspicious Yoga in the birth horoscope of a person. Hence it is also known as Kala Sarpa Dosha. Kala Sarpa Yoga is formed when all planets are positioned between Rahu and Ketu in Janma Kundali. In such Kundali any five consecutive houses are always empty.
All Kala Sarpa Dosha have been categorized into twelve categories.
Some astrologers also consider partial Kala Sarpa Dosha. In Partial Kala Sarpa Dosha, all planets except one are positioned between Rahu and Ketu. As partial Kaal Sarpa Dosha is not widely accepted, Drik Panchang does not list them.
