Pitra Dosha Calculator
Pitra Dosha Calculator
Pitra Dosha — sometimes written Pitru Dosha — is read as unfinished ancestral karma showing up in the birth chart, chiefly through the Sun and the 9th house of father and lineage. This calculator checks your chart against the widely used classical indicators and tells you exactly which rule, if any, applies — instead of a vague yes or no.

The Lagna changes roughly every 2 hours, so the exact birth time and place are needed for a correct answer.
What is Pitra Dosha?
In Vedic astrology the Sun stands for the father and the male ancestral line, and the 9th house stands for father, forefathers and dharma. Pitra Dosha is the idea that karmic debts toward the ancestors — duties left undone, or wrongs in the lineage — leave a mark on these parts of the chart, sometimes felt as recurring obstacles in family, progress or peace of mind.
The most accepted signs are an afflicted Sun — joined with Rahu, Ketu or Saturn — and an afflicted 9th house, such as a node or Saturn sitting there, or the 9th lord falling into a difficult house. This calculator looks for each of these and reports which ones it finds.
Where Pitra Dosha comes from — and where it doesn't
It's worth being honest about the source. The Sun and 9th-house significations are genuinely classical, but the popular “Pitra Dosha checklist” you see online is a later synthesis, not a single chapter of Brihat Parashara Hora Shastra. Lal Kitab frames it around the Sun afflicted by Saturn or the nodes, with its own ritual remedies.
Because the rule set is a synthesis, we treat it carefully: the calculator separates the strong, widely agreed indicators from the weaker ones, and names the exact placement that triggered each. The goal is an honest reading you can reflect on, not a guilt-driven verdict.
The indicators this calculator checks
It looks for the mainstream Parashari signs: the Sun conjunct Rahu (the core indicator), the Sun conjunct Ketu or Saturn, Rahu/Ketu or Saturn placed in the 9th house, the 9th lord sitting with a node or Saturn, and the 9th lord fallen into a difficult 6th, 8th or 12th house. An eclipse-afflicted Moon (joined to a node) is included as a softer, secondary sign. For each, you see exactly which planets are involved.
What to do with a Pitra Dosha result
If the calculator flags Pitra Dosha, read it as a theme to work with rather than a sentence. Traditional responses are ancestral — Shraddha and Tarpan rites, Pitru Paksha observances, and acts of service and gratitude toward elders and forebears. None of that requires fear. If it matters to you, take the result to a qualified astrologer who can weigh the strength of the Sun and 9th house in full.
The signs of Pitra Dosha, one by one
The calculator checks each classical indicator and names the ones present in your chart. Here is what each placement means, and how heavily it tends to weigh.
Sun joined with Rahu
The core indicator
The Sun — significator of the father — eclipsed by Rahu is the strongest and most cited sign, read as an unsettled debt in the paternal line. It often shows as distance or difficulty around the father, yet a strong, well-placed Sun can carry it far more lightly.
Sun joined with Ketu
A nodal affliction
Ketu with the Sun gives a subtler version of the same theme — a sense of something missing or detached in the father bond or lineage duty. It can incline toward spiritual seeking as much as struggle, depending on the Sun's overall strength.
Sun joined with Saturn
A widely cited pairing
The Sun with Saturn is read as the father significator under pressure — duty, restraint or coolness around the paternal figure. Where the Sun is otherwise dignified, the same combination can mature into real responsibility and discipline.
Rahu or Ketu in the 9th house
A node on the house of lineage
A node sitting in the 9th — the house of father, forefathers and dharma — is taken as ancestral karma touching the line directly. It can unsettle faith and fortune, but it also often pushes a person toward their own spiritual path.
Saturn in the 9th house
Weight on the house of lineage
Saturn in the 9th weighs on dharma, fortune and the father's house, frequently felt as delay or a heavy sense of duty toward elders. Handled well, that same Saturn gives depth, patience and a hard-earned faith.
The 9th lord afflicted
Lineage lord with a node or Saturn
When the lord of the 9th house itself sits with Rahu, Ketu or Saturn, the ruler of fortune and lineage is under strain — the affliction reaches the house through its lord. How much it matters depends on how strong that lord is otherwise.
The 9th lord in a difficult house
Fallen into the 6th, 8th or 12th
The 9th lord falling into a difficult 6th, 8th or 12th house scatters the strength of fortune and the father's house into struggle, loss or hidden matters. A strong lord can still deliver, but the theme of ancestral effort is clearly marked.
The Moon joined with a node
A softer, secondary sign
An eclipse-affected Moon — joined to Rahu or Ketu — is included by some traditions as a gentler, secondary hint rather than a core indicator. It speaks more to emotional inheritance than to a firm verdict, and is best weighed lightly.
Any single indicator raises the flag, and the calculator names the exact placements it finds. Read their number and strength together — one soft sign is not the same as several strong ones.

Frequently Asked Questions
- How do I know if I have Pitra Dosha?
- Pitra Dosha is indicated when the Sun is afflicted by Rahu, Ketu or Saturn, or when the 9th house of father and ancestors — or its lord — is afflicted. Enter your birth details above and the calculator checks each classical indicator and names exactly which placements, if any, are present in your chart.
- What are the main signs of Pitra Dosha in a chart?
- The most accepted are the Sun joined with Rahu (the core sign), the Sun with Ketu or Saturn, a node or Saturn in the 9th house, the 9th lord sitting with a node or Saturn, and the 9th lord fallen into the 6th, 8th or 12th. The calculator reports each one it finds.
- Is Pitra Dosha mentioned in the classical texts?
- Partly. The Sun-as-father and 9th-house significations are classical, but the popular Pitra Dosha indicator list is a later synthesis rather than one passage of Brihat Parashara Hora Shastra. We say so plainly and separate the stronger indicators from the weaker ones.
- What are the remedies for Pitra Dosha?
- Traditional responses are ancestral rather than gem-based: Shraddha and Tarpan rituals, observances during Pitru Paksha, and service and gratitude toward elders and ancestors. Lal Kitab adds its own remedies. A result here is a starting point — confirm it with a qualified astrologer before acting.
- Do I need my exact birth time for this?
- Yes, for the 9th-house checks. The Sun-and-nodes conjunctions can be read from the date, but placing the 9th house and finding its lord needs your ascendant — which depends on your exact birth time and place. Without a time we assume noon and flag that the house-based results may change.
