कालसर्प योग Kalasarpa Yoga
Kalasarpa is when all seven grahas fall on one side of the Rahu–Ketu axis. It is uncommon, the verdict can turn on a single degree, and this page shows you how close yours was.
How this is judged, the twelve names, and why the margin matters
The rule. Rahu and Ketu sit exactly opposite each other, cutting the zodiac in half. If all seven grahas — Surya, Chandra, Mangal, Budha, Guru, Shukra and Shani — fall in the half running forward from Rahu to Ketu, that is Kalasarpa. If they all fall in the other half instead, many traditions name it Kala Amrita and treat it as the gentler of the two. One graha on the wrong side and neither applies.
The twelve names go by the house Rahu occupies, which is why the name needs a birth time and the yoga itself does not:
| 1 Anant | 2 Kulik | 3 Vasuki | 4 Shankhapal |
| 5 Padma | 6 Mahapadma | 7 Takshak | 8 Karkotak |
| 9 Shankhachud | 10 Ghatak | 11 Vishdhar | 12 Sheshnag |
Why we show the margin. This is the one reading on this site that a single graha can flip. Almanacs differ on which Rahu they use — the mean node, as we do, or the true node, which wanders up to about a degree and a half either side. A chart with a graha inside that margin can honestly read Kalasarpa on one site and not on another, and neither is wrong. So we show how close the nearest graha came, and say so when it is close.
Without a birth time the Moon could be anywhere across about thirteen degrees, which is easily enough to change the answer. Where that happens the page says the result is undetermined rather than picking one.
Kalasarpa is a placement, not a sentence. It is uncommon — on our own sampling it holds on roughly seven days in a hundred — and it says nothing on its own about how a life goes.
