Free navamsa chart calculator (D9 chart calculator). Get your navamsa lagna and every planet's D9 sign with its lord — vargottama planets flagged.
The navamsa is the ninth divisional chart (varga) of Vedic astrology, written D9. Each zodiac sign is divided into nine equal parts of 3 degrees 20 minutes, and every planet is re-placed into a new sign according to which ninth it occupies. The result is a second chart derived entirely from your birth chart (D1). 'Nava' means nine and 'amsa' means portion — the ninth portion.
Tradition treats the navamsa as the most important divisional chart after the birth chart itself. It is classically consulted for marriage and the spouse, and as a second reading of every planet's underlying strength: a planet weak in the birth chart but well-placed in D9 is read as having hidden support, while one strong in D1 but afflicted in D9 is read as less reliable than it looks. Practitioners routinely check the D9 before confirming any judgement made from the D1.
Start from the navamsa lagna — the D9 ascendant this calculator reports — and count houses from it just as in a birth chart. Then compare each planet's D9 sign with its D1 sign: note the D9 sign's lord and that lord's condition, and look for vargottama planets (same sign in both charts). The standard method is always comparative — D1 and D9 side by side — rather than reading the D9 as an independent horoscope.
A planet is vargottama ('best of the divisions') when it occupies the same sign in the birth chart (D1) and the navamsa (D9). This happens for specific degree ranges within each sign. Tradition reads a vargottama planet as strengthened — the sign's signal confirmed twice. This calculator flags every vargottama planet in your chart automatically.
Pushkar (or pushkara) navamsas are specific navamsa divisions traditionally regarded as auspicious — 'nourishing' portions of certain signs where planets are held to give supportive results. Classical lists assign two pushkar navamsas to each element's signs. It is a refinement used in muhurta and chart judgement; a planet in a pushkar navamsa is read more favourably, other factors permitting.
The birth ascendant moves through one full sign roughly every two hours, and each navamsa division within it spans only 3 degrees 20 minutes — so the navamsa lagna changes roughly every 13 minutes. A birth time off by even a few minutes can shift it into the next sign. The planets' D9 signs are far more stable, since planets move much more slowly; it is specifically the D9 lagna that demands time accuracy. This tool computes everything with Swiss Ephemeris using the Lahiri ayanamsa (sidereal).
