Pitra Dosha Calculator

Three debts, and the one this page concerns

Vedic thought speaks of three debts carried by everyone born: to the gods (deva rina), to the sages (rishi rina) and to the ancestors (pitri rina). The Vedic formula says the last is repaid through offspring, which is why the classical discussion of a father's curse is framed around progeny. Pitra dosha is the astrological reading of the same idea: certain placements are taken to show that the obligation weighs more heavily in a particular chart.

The calculator does not judge any of that. It tests the chart against five mechanical conditions and reports the ones that hold. What any of them means for a particular family is a question for a reading, and not one this page attempts to answer.

The five indicators

Indicator one asks whether the Sun, the Moon or Rahu occupies the 9th house. The 9th is the house of the father, of dharma and of the ancestors in the traditional scheme, and the Sun and Moon are the natural significators of father and mother. Indicator two asks whether Ketu occupies the 4th, the house of the mother and of one's roots.

Indicator three asks whether the Sun, the Moon, Rahu or Ketu is associated with Mars or Saturn. For this engine, association means sharing a sign, exchanging signs, or aspecting each other — and the aspects counted include the sign aspects as well as the planetary ones. Indicator four asks whether two or all three of Venus, Mercury and Rahu sit together in the 2nd, 5th, 9th or 12th house. Indicator five asks whether the Sun or the Moon shares a sign with Rahu or Ketu.

Houses are counted sign by sign from the lagna, so indicators one, two and four depend on the rising sign and therefore on an accurate birth time. Indicators three and five depend only on the planets, and a chart whose time is uncertain can still be read for those two.

Why most charts meet at least one

Taken together the five indicators cast a wide net, and indicator three casts the widest. It involves four bodies and two planets, each pair able to qualify by conjunction, exchange or any counted aspect, and with sign aspects included it is met by the large majority of charts on its own. Indicator five is met whenever a luminary shares a sign with a node — for the Sun, about a month at a time twice a year, around the eclipse seasons; for the Moon, a little over two days in every fortnight.

The breadth is the honest headline. Put a few thousand random birth moments through all five and nearly every chart meets at least one, with indicator three alone accounting for the great majority. That is why this page gives no overall ‘present’: a label that nearly every chart earns says nothing, and a chart that meets one indicator through a single conjunction is not in the position of a chart that meets four. The page lists the five, marks each one, and leaves the weighing to a reading.

What Parashara describes, and what came later

Brihat Parasara Hora Sastra has a chapter on curses carried over from a previous birth, read in the context of progeny, and a curse from the father is among them. Its combinations are its own, and they are not the five used here. The five indicators belong to later traditional practice, assembled from the significations of the Sun, the Moon, the nodes and the 9th house rather than quoted from any verse.

That history explains both the strength and the weakness of the modern indicators. Their building blocks are sound classical ones — the 9th as the house of the father, the Sun as his significator, the nodes as the agents of eclipse — but the assembly is newer than the blocks, and practitioners assemble them differently. Another calculator may use four indicators, or seven, and report a different set for the same birth.

The 1961 chart: two indicators out of five

With a Scorpio lagna, the 9th house of the worked example is Cancer, and Rahu stands there at 27°41′. That meets indicator one. Indicator three is met several ways at once. The plainest are the Sun at 27°25′ Scorpio sharing its sign with Mars at 27°54′, less than a degree apart, and Ketu at 27°41′ Capricorn sharing its sign with Saturn at 4°17′.

The other three fail. Ketu is in the 3rd, not the 4th. Venus and Mercury do sit together, but in the 1st, a house indicator four does not name. Neither luminary shares a sign with a node: the Sun is in Scorpio, the Moon in Aquarius, the nodes in Cancer and Capricorn. The result marks indicators one and three as met and the other three as not met.

Read plainly, that is two structural features — a node in the 9th, and the Sun and Ketu each sharing a sign with a malefic — rather than a finding about anyone's ancestors. They are placements a reading would look at in the light of the 9th lord, the condition of the Sun and the running dasha; the count settles nothing by itself.

Observances in the tradition

The traditional response to the ancestral debt is the same however many indicators a chart meets. Shraddha rites on the anniversary of a death, tarpan — offerings of water mixed with sesame — and the fortnight of Pitru Paksha, usually in September or early October, are kept by families across India as part of ordinary religious life.

They are described here as tradition, not prescribed. Whether to keep them, and how, is a matter for the family and its own priest or elders; nothing in the calculation depends on it, and a met indicator is no reason to fear for anyone.

How do I check pitra dosh in my kundli?

Enter your date, time and place of birth above. The calculator builds the chart and tests it against five traditional indicators: the Sun, Moon or Rahu in the 9th; Ketu in the 4th; a luminary or node associated with Mars or Saturn; two of Venus, Mercury and Rahu together in the 2nd, 5th, 9th or 12th; and a luminary in a node's sign. Each is shown as met or not met; there is no overall verdict.

Are pitra dosha and pitru dosha the same thing?

Yes. Pitri, pitru and pitra are different transliterations of the Sanskrit word for the forefathers, and dosh is the everyday Hindi pronunciation of dosha. Searches for pitra dosh, pitru dosh and pitri dosha all point to the same idea, though the exact checks behind the name vary from one tradition, and one calculator, to another.

Is pitru dosh mentioned in the classical texts?

Not in the form used here. Brihat Parasara Hora Sastra discusses a curse from the father, among other curses from a past birth, in its treatment of progeny, and gives combinations of its own. The five indicators this calculator checks come from later practice, which built them out of older significations of the Sun, the Moon, the nodes and the 9th house.

Why does my chart meet a pitra dosha indicator when nothing seems wrong in my family?

Because the indicators are broad, and most charts meet at least one of them through ordinary placements such as the Sun sharing a sign with Saturn. A met indicator describes the geometry of the chart, not the history of a family, and it predicts nothing. It points to placements a reading might look at, alongside everything else in the chart.

When is Pitru Paksha observed?

It is the waning fortnight of the lunar month of Bhadrapada in the amanta calendar used in the South and West, which the purnimanta calendar of the North places in Ashvin. It usually falls in September or early October and closes on Mahalaya Amavasya, also called Sarva Pitru Amavasya, the new moon given to all the ancestors.

Can pitra dosha be checked without an exact birth time?

Partly. Two of the five indicators — a luminary or node associated with Mars or Saturn, and a luminary in a node's sign — depend only on the planets, so they rarely change across a birth date unless the Moon, or another planet, changes sign that day. The other three count houses from the lagna and need a time accurate enough to fix the rising sign.
