D9 Navamsa Chart Calculator
A free navamsa (D9) chart calculator — each sign cut into nine parts of 3 degrees 20 minutes, with every planet placed by its exact longitude.
The navamsa, or D9, is the ninth divisional chart. Each 30-degree sign is split into nine parts of 3 degrees 20 minutes, and a body is re-placed into the sign its own part points to. Classically it is the varga consulted for marriage and matters of the spouse, for dharma, and for a planet's overall strength. Kundli Studio derives it from astronomical longitudes rather than a printed grid.
The run of nine starts from the movable sign of the element — Aries for a fiery sign, Capricorn for earthy, Libra for airy and Cancer for watery — counting forward one sign per part, so it begins at the sign itself only for the four movable signs. Since that start is set by element, the three signs of an element share one identical map, and twelve signs reduce to four. A navamsa also measures exactly what a nakshatra pada does — 3 degrees 20 minutes — and both grids run from 0 degrees Aries, giving 108 of each.
The nine navamsas of Pisces
Pisces is watery, so its nine navamsas run from Cancer. In a sample chart cast for 1 January 1990, 12:00 noon IST at Chennai — fabricated, never anyone's birth — the Ascendant falls at 16 deg 28' Pisces.
| Part | Arc within Pisces | Navamsa sign |
|---|---|---|
| 1 | 0 deg 00' - 3 deg 20' | Cancer |
| 2 | 3 deg 20' - 6 deg 40' | Leo |
| 3 | 6 deg 40' - 10 deg 00' | Virgo |
| 4 | 10 deg 00' - 13 deg 20' | Libra |
| 5 | 13 deg 20' - 16 deg 40' | Scorpio |
| 6 | 16 deg 40' - 20 deg 00' | Sagittarius |
| 7 | 20 deg 00' - 23 deg 20' | Capricorn |
| 8 | 23 deg 20' - 26 deg 40' | Aquarius |
| 9 | 26 deg 40' - 30 deg 00' | Pisces |
16 deg 28' falls in the fifth part, 13 deg 20' to 16 deg 40', so the navamsa lagna of that sample is Scorpio. Mars at 16 deg 07' Scorpio is also a fifth part and returns to Scorpio; Mercury at 2 deg 00' Capricorn, a first part, returns to Capricorn.
How to read the result
On the divisional chart screen the D9 is the second of the six cells drawn by default, labelled D-9_navamsa in its selector. Begin at the As badge, which marks the navamsa lagna. Narasimha Rao's textbook treats every varga as an independent chart, so the D9's houses are counted from that sign; in the North Indian style it occupies the top central house. The small number printed in each box is a sign number, 1 for Aries through 12 for Pisces. Saravali relates physical appearance to the navamsa lagna, among other factors.
Next set each graha's D9 sign beside its rasi sign. BPHS 6.42-53 counts a division that falls in a graha's own, exaltation or moolatrikona sign as a good varga, and many BPHS rules turn on a graha standing in its own or exalted navamsa. A token in brackets, such as (Ve), marks a graha retrograde at birth; motion is read from the birth chart, so the brackets repeat in every cell.
Hover a token to see its exact place. The tooltip gives the navamsa sign and an in-navamsa degree — the degree within the D1 sign multiplied by nine, less whole thirties — which tracks progress through the 3 deg 20' part. Mars in the sample above reads Scorpio 25:08:51, inside the closing third of its navamsa. BPHS 7.13-16 grades effects as full, medium and nil at the beginning, middle and end of a hora and applies the same grading to the navamsa.
Key terms
- Navamsa lagna
- Shown by the As badge in the D9 cell and counted as house 1 of the D9; Narasimha Rao also reads this chart from a second reference, the karakamsa.
- Karakamsa
- The navamsa sign occupied by the atmakaraka, as BPHS defines it; on the D9 cell it is simply the sign holding that graha.
- Atmakaraka
- In BPHS, the graha that has traversed the maximum number of degrees within its sign; for Rahu the degrees are counted back from 30.
- Moolatrikona
- With the own sign and the exaltation sign, one of three placements Narasimha Rao says make a planet very strong in a chart; in the D9 it counts towards a good varga.
- In-navamsa degree
- The degree a D9 tooltip prints: the body's degree within its D1 sign times nine, less whole thirties, running from 0 to 30 across one part.
- Good varga
- BPHS's term for a division that falls in a graha's own, exaltation or moolatrikona sign, or in a sign owned by a kendra lord from the arudha lagna.
The D9 among 23 divisions
The navamsa is one of 23 divisional charts built from a single birth entry here, from the D1 Rasi to the D144 — the D9 sits beside the D10 and the D60.
Four maps, twelve signs
The nine-part run is seeded by element, so Aries, Leo and Sagittarius give one identical map and the twelve signs collapse to four. That seed is applied for every body.
3 of 20 Vimsopaka points
In the sixteen-fold Shodasavarga weighting the navamsa carries 3 of the 20 Vimsopaka points, third-heaviest behind the D60's 4 and the Rasi's 3.5 — the weights Vimsopaka bala uses.
Common questions
What is a navamsa chart?
The navamsa, also spelled navamsha, is the D9 chart — each sign divided into nine parts of 3 degrees 20 minutes, every body re-placed into the sign its part points to. It is one of the sixteen classical vargas.
How do I calculate the navamsa manually?
Divide the planet's degrees within its sign by 3 degrees 20 minutes and keep the whole number, 0 to 8. Count that many signs forward from the element start — Aries for fiery, Capricorn earthy, Libra airy, Cancer watery. The sign reached is the navamsa.
What is the navamsa lagna?
It is the navamsa sign of the Ascendant, found by applying the same rule to the Ascendant's own longitude; there is no separate formula. In the sample above the Ascendant is in the fifth navamsa of Pisces, giving Scorpio.
Do I need my exact birth time?
For the Ascendant, yes. A navamsa is 3 degrees 20 minutes wide, and the ascending degree covers roughly that in about thirteen minutes on average — a rate that varies with latitude and rising sign.
What is the karakamsa in a navamsa chart?
BPHS calls the navamsa occupied by the atmakaraka the karakamsa. In the 1990 sample chart Saturn, at 21 deg 55' Sagittarius, has covered more of its sign than any other graha, so it is the atmakaraka; its D9 sign is Libra, which makes Libra the karakamsa — the 12th sign from that chart's Scorpio navamsa lagna.
Which navamsa method does this calculator use?
The Parasari method of BPHS 6.12, the element-seeded count described above. The calculation engine also contains Krishna Mishra, Kalachakra and parivritti variants of the navamsa, but the app does not ask for them, so the D9 drawn here is the engine's default, the Parasari chart.
