Kaal Sarp Yoga (or Dosha) is an astrological combination in Jyotisha. It has importance in mundane as well as natal astrology. It is considered a negative yoga, having detrimental effect on the natives possessing such yoga in their birth charts.

It is formed when all 7 planets considered in Vedic Astrology (Sun, Moon, Mars, Venus, Jupiter, Saturn, Mercury) are placed between Rahu (Moon’s North Node) and Ketu (Moon’s South Node) in the natal chart.
