Thirumana Porutham Calculator
Check Tamil and Malayalam marriage star match from two birth stars. The tool computes all ten South Indian poruthams and shows the rule applied for each, then reports two independent outputs - a total out of ten, and the Rajju and Vedha gates - rather than an accept-or-reject verdict. Add full birth details for the Chevvai/Chovva and Papasamyam screenings. This is the South Indian system, not North Indian guna milan.
In short
Tradition commonly looks for 6 of 10 with Rajju and Vedha met. Worth knowing before you read your own number: about 59% of all star combinations already reach 6 or more, so a 6 is closer to typical than to exceptional. Rajju and Vedha are counted in that total and shown again on their own, because tradition weighs them separately - not because they are the demanding checks. They are actually among the easiest to pass; Vashya, at about 13%, is the strict one. Chevvai and Papasamyam need a birth time and are withheld without one rather than guessed.
Check porutham by birth star
Enter each person's Moon birth star (and pada, if known) for the 10 poruthams, Rajju, and Vedha. Chevvai/Chovva dosham and Papasamyam need full birth details.
Full match with birth details
Birth date, time, and place for both people give the 10 poruthams plus the Chevvai/Chovva (Sevvai) and Papasamyam screenings. Poruthams are counted from the bride-side star to the groom-side star, so the two roles are not interchangeable.
Seconds optional (defaults to 00). Example: 5:30:00 PM.
Seconds optional (defaults to 00). Example: 5:30:00 PM.
Dates from 1900 onwards. Birth-time precision matters most when a planet sits near a sign, nakshatra, or pada boundary; use the most accurate time you have.

The ten poruthams, and what each one checks
Each entry states the rule this calculator actually applies. Where published sources disagree, we say so rather than presenting one convention as settled.
1. Dina - day-to-day wellbeing
Counts from the bride-side star to the groom-side star; favourable counts score the point. Same-star cases are allowed for a specific subset of stars rather than universally.
2. Gana - temperament
Compares the two temperament classes (Deva, Manushya, Rakshasa). Same-class pairs score in full. The pairing is order-sensitive, so swapping the two sides can change the result.
3. Mahendra - progeny and support
Met when the count between the stars falls in the set 4, 7, 10, 13, 16, 19, 22, 25. That set is closed under the count reversal, so this one scores the same either way round.
4. Stree Deergha - the wife's longevity and prosperity
Three-way, counting from the bride-side star to the groom-side star: above 13 scores the full point, 8 to 13 scores a half, and 7 or below scores zero. Sources differ on the exact cut; we use the commonly published one and record the disagreement.
5. Yoni - physical compatibility
Each star maps to an animal class. Scored as a binary here - designated enemy pairs score zero, everything else scores the point. The 0-to-4 graded scale seen elsewhere belongs to North Indian Ashtakoota, not to this system.
6. Rasi - family harmony
Counts the groom-side moon sign from the bride-side one. Positions 3, 4, 5, 7, 9, 10 and 11 score the point; 6 and 8 (Shashtashtaka) and 2 and 12 (Dwidwadasha) score zero. Same sign (Eka-Rasi) is its own case and is ORDER-SENSITIVE: it scores only when the bride-side star is not before the groom-side star. Position 4 is genuinely unsettled - at least one published source marks it adverse - and we follow the more common treatment of counting it favourable rather than picking a side silently.
7. Rasi Athipathi - the moon-sign lords' relationship
Compares the two moon-sign lords. Sharing the same lord scores in full, as does mutual friendship; any enmity in either direction scores zero, and the remaining mixed case scores a half. Disclosure: the friendship relation is directional in the classical tables, and no source we found specifies how the two directions collapse into one score. That collapse rule is ours, chosen for consistency and stated here rather than presented as traditional.
8. Vashya - mutual attraction
Uses a dedicated 12-by-12 table for this system, not the Ashtakoota Vashya groups. It is directional: it asks whether the bride-side sign falls within the groom-side sign's set.
9. Rajju - the marriage's longevity - counted, AND surfaced as a gate
Stars fall into five bands, and the same band on both sides is the adverse case. This scores a point in the total like any other porutham AND is shown again as its own gate, because tradition weighs it separately. Met in about 79% of all ordered combinations. A documented mitigation - where one star is ascending and the other descending within the same band - is NOT applied here; see the note below.
10. Vedha - mutual affliction - counted, AND surfaced as a gate
Specific star pairs are held to afflict one another. Like Rajju it scores a point in the total AND is shown again as its own gate. Met in about 96% of all ordered combinations, which makes a Vedha failure uncommon.
How selective is a porutham score, really?
Most calculators hand you a number without saying what it is worth. We computed the full distribution instead. Across all 11,664 ordered pada-level star combinations, about 59% reach 6 or more, about 22% reach 7 or more, and about 4% reach 8 or more.
The individual poruthams are wildly uneven, which is worth knowing before reading any single result. These figures are the share of combinations scoring the FULL point, so they understate the three poruthams that can also score a half (Gana, Stree Deergha and Rasi Athipathi) - Gana for instance scores the full point in about 33% but scores something in far more. Vashya is by far the hardest to satisfy, taking the full point in only about 13% of combinations, and it has no half tier; Mahendra, also all-or-nothing, takes it in about 30%. Rajju and Vedha sit at the OTHER end: they are met in about 79% and 96% of combinations respectively, making them two of the easiest to pass. So when tradition singles them out as gates, that is a cultural weighting rather than a statistical one, not a sign that the checks are demanding. The two are not alike either: a Vedha failure is genuinely rare at about 4% of combinations, while a Rajju failure happens in roughly 21% - about one pairing in five, which is common enough that seeing one says little on its own. Both are counted in the total like every other porutham and shown again separately because families weigh them that way.
What these numbers are, precisely: shares of rule combinations, produced by running the engine over every ordered pair of the 108 star-and-pada states. They are an arithmetic property of the rule set, not a statistic about real couples, whose birth stars are not uniformly distributed. We publish them so a score can be read in context, not as a claim about people.
Porutham vs North Indian guna milan
These are two different systems and their numbers are not comparable. North Indian matching uses Ashtakoota - eight kootas totalling 36 gunas - while South Indian matching uses these ten poruthams. A chart can look strong in one and weak in the other without either being wrong, because they weight different factors. Two divergences are worth knowing: Yoni is scored 0 to 4 in Ashtakoota but is a binary check here, and the Mars-affliction house set differs, so Chevvai dosham on this page and a Manglik verdict from a North Indian tool can legitimately disagree on the same chart. For the 36-guna reading, use the Kundli Matching calculator. To find a birth star from a date, use the Nakshatra calculator.

Frequently Asked Questions
What is thirumana porutham?
Thirumana porutham (jathaka porutham in Kerala) is the South Indian star-matching system used when considering a marriage. It compares the bride-side and groom-side birth stars across ten checks - Dina, Gana, Mahendra, Stree Deergha, Yoni, Rasi, Rasi Athipathi, Vashya, Rajju and Vedha - and reports how many are met. It is a different system from North Indian 36-guna Ashtakoota matching, so the two produce different numbers and should not be compared directly.
How many poruthams should match for marriage?
Tradition commonly looks for at least 6 of 10 with Rajju and Vedha met, but practice varies by family, community and astrologer, and there is no single authority. The arithmetic is worth knowing: across all 11,664 ordered pada-level star combinations, about 59% already reach 6 or more, about 22% reach 7 or more, and about 4% reach 8 or more. A 6 out of 10 is therefore closer to typical than to exceptional. This tool reports the count and the gates separately and issues no accept-or-reject verdict.
What is the difference between Tamil and Malayalam porutham?
The ten poruthams are the same set of rules in both, and the mainstream sources we checked returned identical Rajju rosters and Vedha pairs. We should be precise about the strength of that agreement, though: one published source does print a divergent Rajju table claiming a Tamil-versus-Kerala split. We did not adopt it, because it is contradicted by the mainstream sources and is internally inconsistent, but it exists and we record it rather than claiming unanimity. Separately, a Rajju mitigation that several sources document - reducing the same-band dosham when one star is ascending and the other descending - is NOT applied in this version, because the per-star ascending/descending assignment was never found published verbatim and we would have had to derive it. What genuinely differs by region is the wrapper: Kerala practice weighs Papasamyam and Chovva dosham heavily, while Tamil practice presents the same ten with Chevvai dosham checked alongside. One further Kerala component, Dasa Sandhi, is treated as mandatory in a full Kerala reading and is NOT implemented here - if you are using this for a Kerala match, that check is missing and you should get it done separately. The language toggle changes presentation, not the rules.
Can I check porutham without the birth time?
Yes, for the ten poruthams. They are computed from the Moon's birth star, so the star - and the pada, where it matters - is enough. Chevvai/Chovva dosham and Papasamyam are different: both need the Ascendant, which cannot be placed without a birth time, so this tool withholds them rather than assuming a noon chart. If you do not know the time, it reads the birth star across the whole birth day and tells you when the day held more than one candidate star instead of silently picking one.
What are Rajju and Vedha, and why are they shown separately?
They are two of the ten poruthams, and they are counted in the total out of ten exactly like the other eight. They are ALSO shown again as their own met/not-met result, because tradition weighs them separately and some families treat a failure as decisive regardless of the total. So the two outputs overlap by design - the gates are not excluded from the score. On the numbers they are among the easiest checks to pass, not the strictest: across all ordered combinations Rajju is met in about 79% and Vedha in about 96%, against about 13% for Vashya, the hardest. That is why a failure in one of them stands out - it is unusual, not because the rule is demanding. One documented Rajju mitigation, where one star is ascending and the other descending within the same band, is not applied in this version.
Is Chevvai dosham the same as Mangal dosha?
They are the same underlying idea - Mars placed in certain houses from a reference point - but the house sets differ, so the two can disagree on the same chart. This page applies the South Indian set: houses 2, 4, 7, 8 and 12, with the 1st house not counted. Our general Mangal Dosha tool uses the wider 1, 2, 4, 7, 8, 12 set, which does count the 1st house. That wider set is not strictly the North Indian convention either - the North Indian reading as published by Drik Panchang omits the 2nd house - so treat it as a broader screen rather than a regional label. That is why the Chevvai result here is deliberately not cross-shown with the Manglik verdict elsewhere on the site: presenting both at once would present a contradiction as a fact.
What is Papasamyam?
Papasamyam is the Kerala practice of comparing the weight of malefic (papa) affliction in the two charts. The comparison this tool implements is DIRECTIONAL, not symmetric: it raises a caution only when the bride-side index EXCEEDS the groom-side index. An equal index, or a higher groom-side index, is not cautioned. That asymmetry comes from the tradition and we surface it rather than smoothing it into a neutral 'balanced' reading. There is no single canonical scheme for scoring the index itself - published methods differ on which planets count, which houses count, and how they are weighted - so this tool shows a disclosed, adapted index and labels it as such, listing the planets, houses and weights it uses and naming what it omits. It is a screening aid, not a verdict, and we make no claim about how common any given value is.
Does a low porutham score mean we should not marry?
No. This is a cultural and traditional input, not a prediction, and the tool deliberately outputs no accept-or-reject. It gives two things - a count out of ten, and the Rajju and Vedha gates - along with the rule applied for each porutham so you can see exactly why each scored as it did. Families weigh these very differently, many disregard them entirely, and an astrologer consulted in person considers far more of the chart than a star match. Treat the output as information about a tradition, not as advice about a relationship.
Sources
Every rule on this page is recorded against published references in our source ledger, including the places where those references disagree with each other. Where a convention is genuinely unsettled - the Stree Deergha threshold, the Rasi fourth-position case, the Papasamyam scheme - we say so rather than picking a side silently. Native-script terminology is used only where two independent native-script publications print the same lexical stem; contested spellings render in English instead of being guessed. For about half the terms the exact full form comes from one of the two sources and the shared stem from both, which is the standard we hold rather than a stricter one.
Two different bodies of sources sit behind this page. The scoring RULES come from published matching references including Prokerala, AstroVed, mPanchang and FindYourFate, with the Chevvai house set following the South Indian convention as published by Drik Panchang. The native-script TERMINOLOGY comes from a separate corpus - Tamil Wikipedia’s thirumana porutham article, Dinamalar and Daily Thanthi star-match tables, Malayala Manorama’s papasamyam explainer and Kairali News’s dasavidha porutham listing. We keep them distinct because a publication good enough to confirm a spelling is not automatically an authority on a rule.
