Kalasarpa Yoga Calculator

What is Kalasarpa Yoga?

Kalasarpa Yoga is a planetary combination in Vedic astrology formed when all seven classical planets — Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn — are positioned on one side of the Rahu-Ketu axis, effectively “hemmed in” between the shadow planets Rahu and Ketu with none of them crossing over to the other side. The name comes from “Kala” (time/serpent) and “Sarpa” (serpent), reflecting the coiled, encircling pattern the planets form around the Rahu-Ketu axis in the chart.

How It Is Determined

This calculator checks the longitudes of all seven classical planets against the positions of Rahu and Ketu in your birth chart (Kundli). If every planet falls within the same half of the zodiac bounded by the Rahu-Ketu axis, the yoga is considered fully present (Poorna/Anant-type Kalasarpa Yoga). If most, but not all, planets fall on one side — with one or two placed close to or just across the axis — it is generally described as a partial (Anshik) Kalasarpa Yoga, which is traditionally considered less intense.

Classical texts further classify Kalasarpa Yoga into twelve named variations (such as Anant, Kulik, Vasuki, Shankhpal, Padma, Mahapadma, Takshak, Karkotak, Shankhchood, Ghatak, Vishdhari, and Sheshnag Kalasarpa Yoga), based on which house Rahu occupies at the time of formation.

Significance & Traditional Interpretation

Traditionally, Kalasarpa Yoga is associated with obstacles, delays, and a sense of struggle in specific life areas depending on its type and the houses involved, though it is equally described as capable of giving sudden, unconventional success once its challenges are worked through. It is worth noting that many modern astrologers regard its effects as far milder than popular belief suggests, and consider the overall chart strength, planetary aspects, and the specific houses affected to be far more decisive than the presence of this yoga alone.
