The Tamil marriage-matching system, scored across twelve poruthams — with Rajju and Nadi weighed most heavily.

The system is often described as "10+2": ten classical poruthams plus Nadi and a twelfth. The ten classical matches are Dina, Gana, Mahendra, Sthree Deergha, Yoni, Rasi, Rasi Athipathi, Vasiya, Rajju and Vedha. To these are added Nadi and a twelfth porutham (Vriksha, sometimes given as Varna), completing the count of twelve.
Each porutham looks at a different facet of the pairing — some at longevity and progeny, some at temperament and mutual attraction, some at family harmony. A high count signals broad agreement across those facets, but the count alone is never the whole story: the tradition treats certain poruthams as far more decisive than others.
In Tamil practice, Rajju and Nadi are the mandatory poruthams. Their failure is weighed most heavily — a strong overall count can still be set aside if either of these two does not agree. Rajju relates to the wellbeing and longevity of the marriage bond; Nadi relates to health and progeny. Because these two carry such weight, juno.date surfaces them clearly rather than burying them inside a single total.
Tamil practice draws on two panchangam (almanac) traditions, and which one you use can change a result at the margins:
| Almanac | Basis |
|---|---|
| Vākya (வாக்கியப் பஞ்சாங்கம்) | Traditional; positions computed by formula. |
| Thirukanitha (திருக்கணிதப் பஞ்சாங்கம்) | Modern (drik); observation-corrected. |
The two agree on most poruthams. The main practical difference shows up in the Yoni table: the traditional (Vākya) split keeps finer animal and gender distinctions, while the modern (Thirukanitha) one merges some of them. Rather than pick a side, juno.date shows both side by side, so you can see exactly where — and why — a verdict shifts between the two. For most couples the two almanacs will tell the same story; when they part ways, it is usually the Yoni row that explains it, and seeing both makes that transparent rather than hidden inside a single verdict.
