Navamsa (D9) Chart Calculator
See your navamsa, the ninth-division chart Vedic astrologers read alongside the birth chart: each planet's D9 sign and your D9 rising sign.
The navamsa, or D9 chart, divides each 30° sign into nine parts of 3°20′ and gives each part a sign of its own, so every planet gets a second, finer placement. Vedic astrologers read it for marriage and partnership and to judge how strong a planet really is beneath its birth-chart sign. Enter your birth details below to see your D9.
Calculate your D9
What the navamsa is
Your birth chart (the D1, or rashi chart) places each planet in one of twelve signs. Divisional charts (vargas) slice each sign into smaller pieces and map them back onto the zodiac. The navamsa is the ninth division ("nava" is nine, "amsa" part), 108 slices in all.
That matches the nakshatras: 27 nakshatras of four padas each are also 108 slices of 3°20′, so every pada is exactly one navamsa. Your Moon's pada, from the nakshatra calculator, gives its navamsa sign.
How the signs are counted
The count for each sign starts from a point set by its element: fire signs (Aries, Leo, Sagittarius) count from Aries, earth signs (Taurus, Virgo, Capricorn) from Capricorn, air signs (Gemini, Libra, Aquarius) from Libra, and water signs (Cancer, Scorpio, Pisces) from Cancer.
Example: Venus at 8° Leo is in Leo's third navamsa (6°40′ to 10°). Leo is fire, so count Aries, Taurus, Gemini: Venus is in Gemini in the D9. A Moon at 21° Scorpio is in the seventh navamsa (20° to 23°20′); count seven from Cancer and you reach Capricorn.
Why astrologers read the D9
Marriage and partnership. The D9 is the chart traditionally consulted for marriage. Astrologers look at the D9 rising sign and the sign seventh from it, at Venus's D9 sign, and at planets in the D9's seventh house. Read it as what you value in a partner, not a forecast.
The deeper strength of planets. A planet's birth-chart sign shows how it presents; its navamsa sign is read as what it has underneath. A planet that looks strong in the D1 but is debilitated in the D9 is said to promise more than it delivers. One that looks modest in the D1 but sits in its own or exalted sign in the D9 tends to grow stronger with age. Astrologers also check where your atmakaraka falls in the D9.
Vargottama planets
A planet in the same sign in both the birth chart and the navamsa is vargottama, roughly "best of the divisions." It is read as consistent and dependable. It happens in one slice of each sign:
- Movable signs (Aries, Cancer, Libra, Capricorn): the first navamsa, 0° to 3°20′.
- Fixed signs (Taurus, Leo, Scorpio, Aquarius): the middle one, 13°20′ to 16°40′.
- Dual signs (Gemini, Virgo, Sagittarius, Pisces): the last one, 26°40′ to 30°.
The D9 rising sign and your birth time
The navamsa has its own rising sign, found by applying the same rule to your rising degree. The birth-chart lagna changes about every two hours, and each sign holds nine navamsas, so the D9 rising sign changes about every 13 minutes.
Near a changeover, a rounded birth time can put it in the wrong sign, so try your time five or ten minutes either side and see if it holds. Without a birth time there is no D9 rising sign. The planets' D9 signs still work, but the Moon changes navamsa about every six hours, so its D9 sign needs at least a rough time.
How to read your results
The navamsa section lists each planet's D9 sign, plus your D9 rising sign if you gave a birth time. Set it beside the planet table's birth-chart signs:
- Spot vargottama planets: the same sign in both lists.
- Check dignity: note planets in their own or exalted sign in the D9 (strong) and any in debilitation (weaker), using the table below.
- Look at partnership: the sign seventh from your D9 rising sign, and Venus's D9 sign.
- Read it with the birth chart, not instead of it. The D9 refines your Vedic birth chart; it doesn't replace it.
| Planet | Own sign | Exalted | Debilitated |
|---|---|---|---|
| Sun | Leo | Aries | Libra |
| Moon | Cancer | Taurus | Scorpio |
| Mars | Aries, Scorpio | Capricorn | Cancer |
| Mercury | Gemini, Virgo | Virgo | Pisces |
| Jupiter | Sagittarius, Pisces | Cancer | Capricorn |
| Venus | Taurus, Libra | Pisces | Virgo |
| Saturn | Capricorn, Aquarius | Libra | Aries |
Questions people ask
What is a navamsa chart?
The navamsa, or D9, is a divisional chart in Vedic astrology. It splits each 30° sign into nine parts of 3°20′ and gives each part a sign, so every planet gets a second placement. It is the most used chart after the birth chart, read for marriage and partnership and for the underlying strength of each planet.
Is the navamsa only about marriage?
No. Marriage is its best-known use, but astrologers also read the D9 for how strong each planet is beneath its birth-chart sign, and many see it as showing how your life matures over time. A planet weak in the birth chart but strong in the D9 is often read as improving with age.
What does vargottama mean?
A planet is vargottama when it occupies the same sign in the birth chart and the navamsa. It happens in the first navamsa of movable signs, the middle one of fixed signs and the last one of dual signs. Vargottama planets are read as strong and consistent. Compare the two sign lists in your results to find yours.
Why does my D9 rising sign differ from another calculator?
Usually because of birth time. The D9 rising sign changes about every 13 minutes, so a few minutes' difference, or a different time zone rule for your birthplace, can move it. A different ayanamsa can shift it too. AstroCall uses the Lahiri ayanamsa; try your time a few minutes either side to see how stable yours is.
