# Pitra Dosh Calculator Pitra dosha is a reading taken from the 9th house, its lord and the Sun, the three places the tradition looks for what is carried down from the paternal line. This page checks the six indicators the texts state most consistently, names which one fired and why, evaluates the cancellations the same texts give, and shows the whole working instead of a verdict. ## What is pitra dosha, and where does the idea come from? Pitra dosha (पितृ दोष, the ancestral affliction) is read as an unsettled account with the paternal line showing in the chart. The honest history is worth stating, because most pages skip it. The name itself is late: it is Lal Kitab and modern practice that gathered a set of Sun-and-9th-house placements under one label. What the classical Brihat Parashara Hora Shastra carries is pitru shapa, the ancestral curse, read from the 9th house, its lord and the Sun, the Sun standing for the father and the 9th for the forefathers and for dharma. So the indicators on this page are real and traceable, but the package they are sold in is a twentieth-century arrangement, and a calculator that presents it as an ancient verdict is overstating what the sources say. ### Why the 9th house carries the forefathers The 9th is the house of the father, of dharma and of what comes down rather than what is earned. Parashara reads inheritance in the widest sense from it (teaching, merit, lineage), which is why an affliction there is the placement writers reach for when they describe an ancestral debt. Read it beside the 9th lord: a house with a strained lord is read as strained itself, and a house with a dignified lord is read as holding its own. ### Why the Sun stands in for the father The Sun is the sthira karaka of the father in Parashari reading: a fixed significator, the same in every chart, unlike Jaimini's chara karakas which are assigned per chart. That is why the Sun is the second place the reading looks, and why Saturn, Rahu or Ketu on it is the first indicator in almost every listing. It is a convention of the system, not an observed fact about fathers. ## Which indicators does this calculator actually check? Six, and each one is shown with the rule that produced it and the reason it did or did not fire. They are: the Sun conjunct or aspected by Rahu, Ketu or Saturn; Rahu or Ketu in the 9th house from the lagna; the 9th lord in the 6th, 8th or 12th, or conjunct one of those three malefics; the Sun in the 9th with a malefic in the same sign; Rahu in the 5th; and Saturn, Rahu or Ketu aspecting the 9th. Different writers weight these differently and some add others, so the result names the six it used rather than implying a settled list. The indicators that did not fire are printed too, because a check you cannot see is a check you cannot argue with. ### The aspect rule this page uses Classical graha drishti, counted by whole signs: every graha aspects the 7th from itself, Mars adds the 4th and 8th, Jupiter the 5th and 9th, Saturn the 3rd and 10th. Rahu and Ketu are given the 5th, 7th and 9th, and that one is a convention rather than a rule, since Parashara assigns the nodes no aspect of their own. Where an indicator rests on a node's aspect, the result labels it so you can discount it if you follow a writer who does not grant it. ### Why conjunction alone counts for the Sun in the 9th The fourth indicator asks for the Sun in the 9th with Saturn, Rahu or Ketu in the same sign, and stops there. Allowing an aspect to satisfy it as well would make it a duplicate of the first indicator, which already covers a malefic aspect on the Sun, and a list that counts the same placement twice inflates its own severity word. Keeping them apart is the difference between six checks and five checks wearing six names. ## How is the severity word decided, and what does it mean? By counting, and by nothing else. No indicator present is reported as none; one or two as mild; three or more as notable. The reason it is a count rather than a score is that the texts give no scoring scheme to weigh the indicators against each other. A weighted total would be a number we invented, dressed as tradition. So the word is a summary of how many of the stated conditions a chart meets and nothing more. It is not a measurement of anything in a life, it does not rank one chart against another, and the same chart read with a different aspect convention or a cusp-based house system can land on a different word. Read the indicator list; the word is only the shortest way to say how long that list is. ## What cancels pitra dosha, and are the cancellations evaluated? They are evaluated on your chart, not listed as reassurance. The texts give three, and the result says for each one whether it applies and why: Jupiter aspecting the 9th house or the Sun, which is the cancellation offered most readily because Jupiter is the karaka of dharma; the 9th lord exalted or in its own sign, on Parashara's general principle that a house with a dignified lord holds its own; and the Sun exalted or in Leo, the significator of the father in strength. A report that counts afflictions and stays quiet about the cancellations from the same sources is not reporting the tradition, it is selling worry, so both halves are computed and both are shown. ## What remedies does the tradition give for pitra dosha? The observances are older than the label and most are kept in ordinary households with no reference to a chart at all. Pitru Paksha, the fortnight of water offerings before Sharad Navratri, is named first almost everywhere. Shraddha on the tithi a parent or grandparent passed is the annual rite. Annadana, feeding brahmins, the poor, crows and cattle, is the act the smritis attach to the ancestors above all others. Pilgrimage to Gaya, Trimbakeshwar, Haridwar or Rameshwaram for ancestral rites is custom: a place people have gone for centuries, not a transaction. We list these because they are what the tradition prescribes, not as a prescription of our own, and nothing here needs to be bought. ### Pitru Paksha is a calendar observance, not a repair The fortnight falls at the same point of the lunar calendar every year and is kept by families whether or not anyone has looked at a chart. Treating it as a fix that a calculator has prescribed inverts what it is. If the observance already runs in your family, an indicator list changes nothing about it; if it does not, the reason to take it up is that you want to, not that a page counted two placements in your ninth house. ### Annadana asks nothing of an astrologer Feeding is the remedy with the lowest barrier and the least room for anyone to stand between a person and the act. It needs no muhurat, no specialist and no fee, which is exactly why it is worth naming beside the pilgrimages. A reader who has just been handed a severity word should know that the tradition's most emphasised response to the ancestors costs nothing and can be done this afternoon. ## Do I need my exact birth time for a pitra dosha reading? Yes, because five of the six indicators are counted from the ascendant, and the ascendant moves through a whole sign in roughly two hours. Get the lagna wrong and the 9th house is a different sign, its lord is a different graha, and the house numbers of Rahu and of the Sun all shift: the reading does not nudge, it rotates. Only the first indicator, a malefic on the Sun, survives a wrong lagna, because it is judged from the Sun's own sign. A birth time out by a few minutes matters much less than one out by a few hours, but near a sign boundary even minutes can move the ascendant. If the time is genuinely unknown, treat any pitra dosha output as one of twelve possible readings rather than as yours. ## Why do two sites give me different pitra dosha results? Because they are answering slightly different questions and neither one usually says which. Four things move the answer. The indicator list differs between writers: six here, sometimes four, sometimes ten. The aspect convention for Rahu and Ketu differs, and granting or refusing them the 5th and 9th changes results outright. The house system differs: we use whole-sign houses, where a graha's sign is its house, and a cusp-based system such as Bhava Chalit or Placidus can place a graha near a boundary in the neighbouring house. And the ayanamsha differs; this site uses Lahiri, also called Chitrapaksha. A calculator that prints a verdict without naming those four choices is hiding where its answer came from. ### Whole-sign against a cusp-based grid In whole-sign houses the 9th house is simply the ninth sign from the lagna, and any graha in that sign is in the 9th. Bhava Chalit and quadrant systems such as Placidus draw house cusps that do not line up with sign boundaries, so a graha at the very start or end of a sign can be counted in the house next door. Roughly speaking the disagreement only touches grahas near a boundary, but the 9th lord is exactly the sort of placement that lands there. ### Lahiri, and why naming the ayanamsha matters The sidereal zodiac has to be anchored somewhere, and the offset chosen is the ayanamsha. This site uses Lahiri, the Chitrapaksha value, throughout. Different ayanamshas sit up to about a degree apart, which is enough to move a graha across a sign boundary and with it the house it is read in. Two sites quoting different answers while neither names its ayanamsha is the commonest reason an ordinary reader concludes astrology software is arbitrary. ## Frequently asked questions ### Is pitra dosha mentioned in classical texts? Not under that name. The Brihat Parashara Hora Shastra discusses pitru shapa, an ancestral curse read from the 9th house, its lord and the Sun. The phrase pitra dosha and the packaged indicator list belong to Lal Kitab and modern practice, which is why this page names both. ### How do I know if I have pitra dosha in my kundli? Enter your birth date, time and place above. The calculator checks six stated indicators against your chart, names which fired and why, and evaluates the three cancellations the same texts give. Every step of the working is printed so you can check it rather than trust it. ### Does pitra dosha go away? A chart placement does not change, so the question is really about how the reading is used. The tradition's answer is the cancellations (Jupiter on the 9th or the Sun, a dignified 9th lord) and the observances kept during Pitru Paksha. Both are reported here as tradition, not as a fix. ### Which house is pitra dosha seen from? The 9th house, its lord, and the Sun. The 9th carries the father, the forefathers and dharma in Parashari reading; the Sun is the fixed significator of the father. Rahu in the 5th is the one indicator on this page read from elsewhere, for the merit carried forward. ### Does Rahu or Ketu in the 9th house mean pitra dosha? A node in the 9th is the single indicator named most often, so most writers would say yes. This page counts it as one of six rather than as a verdict, and reports whether Jupiter's aspect or a dignified 9th lord cancels it in your chart. ### Can pitra dosha be checked without a birth time? No, not usefully. Five of the six indicators are counted from the ascendant, which moves a whole sign every two hours, so a wrong lagna rotates the entire reading. Only a malefic on the Sun survives an unknown time, and that alone is not the reading. ### Is Kaal Sarp Dosh the same as pitra dosha? No. Kaal Sarp is judged by all seven grahas falling on one side of the Rahu–Ketu axis and has nothing to do with the 9th house or the Sun. The two are separate readings that share only a modern reputation for being alarming. Our kaal sarp calculator handles that one. ### What is the difference between pitra dosha and pitru dosh? Spelling. Pitru is the closer transliteration of पितृ; pitra is the commoner spelling in everyday use, and both name the same reading. Some writers use pitru shapa for the classical version and pitra dosha for the modern packaged one. --- Source: https://vedicsense.in/pitra-dosh-calculator Method: nirayana (sidereal) rashis, Lahiri ayanamsha, whole-sign bhavas, planetary positions to arc-second accuracy.
