Pitru Dosha Calculator

Pitru Dosha and Pitru Shrapa in Jyotish refer to chart combinations traditionally linked to ancestors (pitṛ), obligations toward forefathers, and themes such as progeny and lineage stress. This calculator builds your chart with Lahiri Ayanamsa and applies rule sets from Brihat Parashara Hora Shastra (Pitru Shrapa, Ch. 84), Garuda Purana (Sun with Rāhu/Ketu), and Phaladeepika (afflicted 9th lord, Sun–Saturn, Jupiter, nodes in the 5th or 9th). • Use an accurate birth time and correct birthplace; small errors change houses and the result. • The output is educational—it shows which classical-style conditions match. It is not medical or legal advice and does not replace a qualified Jyotishi or family priest. • Remedies listed are general tradition only; confirm śrāddha, śānti, and mantras with a qualified practitioner.
