# Kaal Sarp Dosh Calculator Kaal Sarp Dosh forms when all seven classical grahas, Sun through Saturn, fall on one side of the Rahu–Ketu axis, leaving the other half of the chart empty. A single graha outside that half breaks it. This calculator checks every graha, names which of the twelve types applies, and shows its working. ## What is Kaal Sarp Dosh (kaal sarp dosh kya hota hai)? Kaal Sarp Dosh, more properly Kaal Sarp Yoga, is a chart shape: all seven classical grahas, Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn, hemmed inside the half of the zodiac running from Rahu to Ketu, with the opposite half empty. Rahu and Ketu are always exactly 180 degrees apart, so they cut every chart into two halves; the yoga is the case where one half holds everything. The image behind the name is a serpent (kaal is time, sarp is serpent), with Rahu the head, Ketu the tail, and the rest of the chart between them. One point settles most arguments about it: if even one graha falls on the other side of the axis, the yoga is not formed. It is not a weaker version of it. That is why a great many charts said to carry Kaal Sarp simply do not, and why this calculator shows you which grahas sit on which side. ## What are the 12 types of Kaal Sarp Dosh? The type is named for the house Rahu occupies from the lagna, which is why the birth time is needed: the lagna changes about every two hours, and the name changes with it. Rahu in the 1st is Anant, the 2nd Kulik, the 3rd Vasuki, the 4th Shankhpal, the 5th Padma, the 6th Mahapadma, the 7th Takshak, the 8th Karkotak, the 9th Shankhachur, the 10th Ghatak (also called Paatak), the 11th Vishdhar and the 12th Sheshnag. Each is a naga from the Puranas, and the names carry no ranking; they are labels for twelve positions of one axis. What actually varies is which pair of houses the axis cuts through, and that is what a reading works from. Three of the twelve are asked about far more than the rest, and those three are below. ### Mahapadma: Rahu in the 6th Rahu in the 6th puts the axis across the 6th and the 12th, the houses of debt, service, obstacles and expenditure. It is the placement the tradition most often treats as workable rather than difficult, because the 6th is a house Rahu is held to suit: an upachaya, read as improving with time, where a graha of appetite and manoeuvre has something to work against. Named for the great lotus, and no graver than the other eleven. ### Takshak: Rahu in the 7th Rahu in the 7th puts the axis across the 1st and the 7th, the houses of the self and of the partner, which is why this is the type raised most often when two charts are compared. The classical reading concerns the relation between those two houses rather than any outcome, and the ordinary questions still apply: what Rahu sits with, who rules the 7th, and how strong that lord is. ### Sheshnag: Rahu in the 12th Rahu in the 12th puts the axis across the 6th and the 12th from the other end, and popular reading associates it with life or work abroad, with solitude and with the inner life, because the 12th is vyaya bhava, the house of what is spent, released, or lived away from home. Named for the thousand-headed serpent on which Vishnu rests. As with the other eleven, the placement is read, not ranked. ## Which Kaal Sarp Dosh is the most dangerous? None of the twelve is ranked in any classical source, and the honest answer to this question is that the ranking circulating online is not a tradition. The twelve names come from the twelve possible houses for Rahu; nothing in the naming grades them. The popular accounts do not even agree with each other (some call Takshak the worst, others Karkotak or Ghatak), and they cannot agree, because there is no text behind the claim. What can be said is which houses the axis touches, and that follows ordinary chart reading: an axis across the 1st and 7th is read for the self and partnership, one across the 6th and 12th for debt, service and expenditure. The weight it carries also depends on things the label ignores entirely: whether Rahu sits with a benefic, the strength of the lord of the sign Rahu occupies, and the dasha running now. We name the type on your chart and tell you which houses it cuts through. We will not rank it for fear. ## What is the difference between Udit and Anudit Kaal Sarp? The two names describe which way round the grahas are hemmed, and nothing else. The yoga is the same shape in both cases, read from opposite ends. Our report calls them "Rahu to Ketu" and "Ketu to Rahu" and shows in a table which grahas sit on which side, so the direction is visible rather than asserted. Popular accounts often claim the reverse form is the harder of the two. That claim has no classical backing, and it deserves the same caution as the ranking of the twelve types. The direction is a real, checkable feature of a chart; the grading attached to it is somebody's opinion. ### Udit: the grahas hemmed from Rahu forward to Ketu Udit means ascending. All seven classical grahas fall in the half of the zodiac running forward from Rahu, so Rahu stands ahead of them in zodiacal motion and Ketu behind. Read as a shape rather than a label, that means Rahu leads the whole chart's weight, which is the observation traditional practice works from. Our table gives each graha's angular distance forward from Rahu, so this is checkable rather than taken on trust. ### Anudit: the grahas hemmed from Ketu forward to Rahu Anudit means descending, and it is also called Ulta or reverse Kaal Sarp. Here the seven fall in the half running forward from Ketu, so Ketu leads and Rahu closes the group. The popular claim that this arrangement is the harder of the two is the same kind of assertion as the ranking of the twelve types, and it has exactly as much classical support behind it: none. The direction is checkable; the grade is not. ## When is Kaal Sarp only partial (Anshik), and when is it not formed at all? These two get confused constantly, and the difference is not one of degree. A graha sitting clearly on the opposite side of the Rahu–Ketu axis from the rest means the grahas are not hemmed and the yoga is not formed at all. A graha sitting within about a degree of the axis itself is the genuinely ambiguous case, and that is what Anshik is for. The distinction matters because the two lead to opposite reports on the same chart, and because collapsing them is how a yoga that is simply absent gets described as a weak one. Our report names the graha responsible in either case and gives its distance from the axis, so the conclusion is checkable instead of asserted. ### Not formed: one graha on the far side of the axis If even one of the seven sits clearly on the opposite side, the grahas are not hemmed and there is no Kaal Sarp Yoga: not partially, not weakly, not at twenty per cent. The condition is a single yes or no about whether the far half of the chart stands empty, and one occupant settles it. Our report names the graha that broke it and says so plainly, which is the honest answer for a great many charts described as Kaal Sarp. ### Anshik: a graha sitting on the axis itself The genuinely ambiguous case: a graha conjunct Rahu or Ketu, within about a degree of the axis, and so arguably neither hemmed nor free. Astrologers differ on how to read it and no rule settles it, so we treat that case as partial, flag which graha is on the axis, and show the reasoning rather than deciding quietly for you. Counting an on-axis graha as outside would suppress a yoga many practitioners would call present. ## Is Kaal Sarp Dosh mentioned in the classical texts? Not in the form used today, and this is the most useful thing anyone can tell you about it. It is absent from the Brihat Parashara Hora Shastra, from Varahamihira's Brihat Jataka and from the other foundational Sanskrit works. The yoga as popularly described is a later addition, spread through the twentieth century, and its attachment to particular paid rituals is more recent still. Many traditional astrologers weigh it lightly for exactly that reason. What is classical is the reading of Rahu and Ketu themselves (the nodes have a long and serious literature), together with the ordinary Parashari machinery of house lords, dignity and dasha. A chart in which every graha is packed into one half of the zodiac is a real and unusual feature, and worth noticing. Treating it as an emergency is a modern habit rather than an inherited one. ## What does Kaal Sarp Dosh mean for reading a kundli? It is one feature of a chart, read after the ordinary work and never instead of it. An astrologer looking at a Kaal Sarp chart still starts where they always start: the lagna and its lord, the dignity of each graha, which houses the strong grahas rule, and the dasha running now. Kaal Sarp adds one specific observation to that: the whole chart's weight is concentrated in one half of the zodiac, with Rahu at one end of it, and the concentration is what is worth reading, far more than the label. The tradition also holds that the yoga is felt chiefly during Rahu and Ketu periods rather than continuously, which is another reason the dasha timeline tells you more than the flag does. Run your full chart alongside this check rather than reading the flag on its own. ## What upay does the tradition prescribe for Kaal Sarp Dosh? First, what we are not doing: VedicSense does not sell puja, takes no commission from anyone who does, and has no interest in whether you perform a ritual. That matters more on this page than on most, because Kaal Sarp is the most heavily monetised dosha in India, and the pressure people feel to pay for it is exactly why the section above about its absence from the classical texts is there. What the tradition itself prescribes is modest and free: the Rahu and Ketu beeja mantras, the Panchakshari and other recitations associated with Shiva, observing Nag Panchami, and offering water at a Shiva temple. Some lineages add a Naga Bali or a Sarpa Shanti at particular kshetras. We give these because they are what the tradition prescribes, not as a prescription of our own. None is required by us, none is a condition of anything, and nobody should be pressured into an expensive ceremony for a yoga the classical texts do not name. If the flag worries you, the useful next step is a full chart reading, not a payment. ## How is Kaal Sarp Dosh calculated from a birth chart? The test is a comparison of longitudes, and it is worth knowing exactly how it runs, because the borderline cases are where calculators diverge. Every graha's sidereal longitude is measured, then each of the seven classical grahas is expressed as its angular distance forward from Rahu. A graha between 0 and 180 degrees of Rahu sits in one half of the chart; one between 180 and 360 sits in the other. If all seven land in the same half, the yoga is formed, and the direction (Rahu to Ketu, or Ketu to Rahu) is decided by which half that is. The one judgement call is a graha sitting almost exactly on the axis: we treat anything within a degree of Rahu or Ketu as on the axis rather than forcing it to one side, because forcing it would silently decide the answer. Naming the type needs one more input, the lagna, since the type is the house Rahu occupies from it. Our report shows the two halves as a table of which grahas fell where, so the conclusion is checkable rather than asserted. ## Frequently asked questions ### What is Kaal Sarp Dosh? Kaal Sarp Dosh forms when all seven classical grahas sit on one side of the Rahu–Ketu axis, leaving the opposite half of the chart empty. Rahu and Ketu are always exactly opposite, so they divide every chart in two. If even one graha falls on the other side, the yoga is not formed at all. ### Kaal sarp dosh kya hota hai? Kaal Sarp Dosh (काल सर्प दोष) is the chart pattern in which all seven grahas from the Sun to Saturn are hemmed between Rahu and Ketu. Kaal means time and sarp means serpent: Rahu is the head, Ketu the tail. The opposite half of the chart stands empty, and one graha outside it breaks the yoga entirely. ### How many types of Kaal Sarp Dosh are there? Twelve, named after the house Rahu occupies from the ascendant: Anant, Kulik, Vasuki, Shankhpal, Padma, Mahapadma, Takshak, Karkotak, Shankhachur, Ghatak, Vishdhar and Sheshnag. Because the type depends on the lagna, and the lagna changes about every two hours, an accurate birth time is needed to name it. ### Which Kaal Sarp Dosh is the most dangerous? None of the twelve is ranked in any classical source. The names are labels for twelve positions of the same axis, and the rankings circulating online contradict each other because there is no text behind them. What can honestly be said is which pair of houses the axis cuts through, read the way any house placement is read. ### What is partial or Anshik Kaal Sarp Dosh? Anshik Kaal Sarp is the case where a graha sits within about a degree of the Rahu–Ketu axis itself, conjunct one of the nodes. Such a graha is arguably neither hemmed nor free, so astrologers differ on it. That is quite different from a graha clearly outside the axis, which breaks the yoga altogether rather than weakening it. ### Is Kaal Sarp Dosh in the classical texts? Not in the form used today. It does not appear in the Brihat Parashara Hora Shastra or in Varahamihira's Brihat Jataka; the yoga as popularly described is a later addition, and its attachment to paid ritual is more recent still. Many traditional astrologers weigh it lightly for that reason. ### What is the difference between Udit and Anudit Kaal Sarp? Udit, or ascending, has the grahas hemmed in the half running from Rahu forward to Ketu; Anudit, also called reverse or Ulta, has them in the half running from Ketu forward to Rahu. Our report shows which grahas sit on each side. The popular claim that the reverse form is harder has no classical backing. ### What are the upay for Kaal Sarp Dosh? The tradition prescribes the Rahu and Ketu beeja mantras, recitations associated with Shiva, observing Nag Panchami, and offering water at a Shiva temple. We list these because they are what the tradition gives, not as a prescription of our own. We do not sell puja, and nobody should be pressured into paying for it. ### Does Kaal Sarp Dosh need an exact birth time? Naming which of the twelve types applies needs an accurate birth time; detecting the yoga at all does not. Whether the yoga is present depends only on the grahas' longitudes, which need the date and place; naming the type depends on the house Rahu occupies from the ascendant, and the ascendant changes about every two hours. Without a reliable birth time we report presence but decline to name the type. ### When is Kaal Sarp Dosh felt, according to the tradition? Chiefly during Rahu and Ketu dasha and antardasha periods rather than continuously, which is how the tradition itself frames it. That is one reason the dasha timeline is more informative than the flag on its own. It is also read against Rahu's dignity and the strength of the rest of the chart. --- Source: https://vedicsense.in/kaal-sarp-dosh-calculator Method: nirayana (sidereal) rashis, Lahiri ayanamsha, whole-sign bhavas, planetary positions to arc-second accuracy.
