⑨ Free Navamsa Chart Calculator — D9 and All Sixteen Divisional Charts

Umbriel's free Navamsa calculator casts your D9 — the divisional chart Jyotish reads for marriage, partnership and the strength behind a placement — along with the whole Shodasha Varga, all sixteen classical divisions, and flags every planet that is vargottama. Sidereal (Lahiri), free, no account.

• What you'll needBirth date, time and place
• What you getYour D9 sign and house for every planet and the Ascendant, vargottama flagged, and a grid of all sixteen divisional charts

A varga divides each sign into equal parts and reads the part a planet falls in as a sign of its own. The navamsa — D9 — divides each sign into nine parts of 3°20′, and it is the divisional chart read most often after the birth chart itself: traditionally for marriage and partnership, and generally as a test of whether a placement that looks strong in the rasi is still strong when you look closer.

A planet that lands in the same sign in D1 and D9 is vargottama — literally best-in-division — and is read as unusually steady and self-consistent. Umbriel flags these rather than leaving you to compare two grids.

⚠️ Each of the sixteen counts from a different starting sign, and that is the part software gets wrong. A varga computed with the wrong starting rule produces a complete, internally consistent and entirely fictional chart — every planet in a sign, nothing obviously broken, and no way for a reader to tell. Umbriel's sixteen are implemented from their individual classical rules, and the D30 is unequal parts because that is what the tradition specifies rather than a thirtieth each.

The full Shodasha Varga is here: D1 rasi, D2 hora, D3 drekkana, D4 chaturthamsa, D7 saptamsa, D9 navamsa, D10 dasamsa, D12 dwadasamsa, D16 shodasamsa, D20 vimsamsa, D24 siddhamsa, D27 nakshatramsa, D30 trimsamsa, D40 khavedamsa, D45 akshavedamsa and D60 shastyamsa. Six are shown by default and the rest are one tap away, because sixteen columns do not fit on a phone and a table nobody can read is not coverage either.

⚠️ A varga gives a sign, not a degree. The division can be expanded back into a full sign for drawing, but that number is a modern convenience and is not what the classical texts assign — printing it as a position would invent a precision the technique does not have. Your pada in the nakshatra table is the same 3°20′ division as the navamsa, so the two always agree.

Each of the sixteen divisions is implemented from its own classical rule rather than from a shared formula with a parameter, because they do not share one: ⚠️ every varga counts from a DIFFERENT starting sign, and a wrong starting rule yields a complete, internally consistent, entirely fictional chart that no reader could detect. The D30 is unequal parts, as the tradition specifies, rather than thirty equal ones. The D60 was verified against a published worked example rather than against a description of the method, since a description can be read two ways and a worked example cannot. Vargottama is reported by comparing the D1 and D9 signs directly. The navamsa is also the source of the pada lord in the nakshatra table on the same page, so the two are computed once and cannot disagree. ⚠️ What the grid prints is a SIGN and not a degree: a division can be expanded back into a full sign for drawing, but that number is a modern convenience rather than what the classical rules assign, and printing it as a position would manufacture a precision the technique does not have. Six of the sixteen are shown by default with the rest one tap away, because sixteen columns will not fit on a phone and a grid that scrolls sideways for ever is not coverage either.
