Navamsa Calculator See your Navamsa (D9) chart, Navamsa Lagna and vargottama planets

The navamsa, or D9 chart, divides every sign of the zodiac into nine equal parts of 3°20′ and maps each part to a sign. The sign a planet's part maps to is its navamsa sign. Vedic astrologers read the D9 alongside the birth chart (D1), especially for marriage and for how strong a planet really is.

Enter your birth details

Use the time from your birth certificate if you have it. The Navamsa Lagna changes about every 13 minutes, so it is the part of the D9 that depends most on the birth time.

What the calculator shows

Everything comes from one chart calculation, the same one the Lagna calculator uses.

Navamsa Lagna

The navamsa sign of your ascendant, its lord and the D9 house that lord sits in, and for how many minutes of birth time it stays the same.

Your D9 chart

The full navamsa chart, with houses counted from the Navamsa Lagna. Switch between North and South Indian styles.

D1 and D9 side by side

For each of the nine grahas: its sign in the birth chart, its navamsa sign and its house in the D9.

Vargottama planets

Planets in the same sign in the D1 and the D9. The result lists them, and marks a vargottama Lagna too.

Exalted and debilitated

Whether each of the seven grahas is exalted, debilitated or in its own sign in the D9. Rahu and Ketu are not marked, because traditions differ on their signs.

Articles on your placements

Links to our articles on your own placements, such as the Sun in the navamsa or Venus in the 8th house of the navamsa, where we have one.

Why the birth time matters

A navamsa is only 3°20′ wide, a ninth of a sign. The ascendant moves through one in about 13 minutes, so the Navamsa Lagna, and with it every D9 house number, can change with a small error in the birth time. The result shows the window of birth times for which your Navamsa Lagna stays the same.

The Moon crosses a navamsa in about 6 hours, so it changes navamsa sign only when it is near an edge. The other planets move far more slowly and rarely change with the birth time. If the result shows a note, those are the placements to double-check.

How DKSCORE calculates the navamsa

Nine parts per sign

Each sign is divided into nine navamsas of 3°20′. A planet at 21.9023° Dhanu is in the 7th navamsa of Dhanu, which runs from 20°00′ to 23°20′.

Where the count starts

The first navamsa of a fire sign is Mesha, of an earth sign Makara, of an air sign Tula and of a water sign Karka. Count on from there: the 7th navamsa of Dhanu, a fire sign, is Tula.

Houses from the Navamsa Lagna

The navamsa sign of the ascendant is the Navamsa Lagna. D9 houses are whole signs counted from it, the same way D1 houses are counted from the Lagna.

Vargottama and dignity

A planet is vargottama when its D1 and D9 signs are the same. Exaltation, debilitation and own signs follow the classical Parashari tables, for the Sun to Saturn.

Sidereal chart

Positions come from a sidereal chart with the Lahiri ayanamsa for your date, time and place of birth.

FAQ

Navamsa calculator: questions and answers

What is the navamsa chart?
The navamsa (D9) is a divisional chart. Every sign is split into nine parts of 3°20′, and each part maps to a sign, so each planet gets a second sign, its navamsa sign. Astrologers read the D9 together with the birth chart (D1), especially for marriage and for the strength of each planet.
How is the navamsa calculated?
Find which of the nine 3°20′ parts of its sign a planet is in, then count that many signs from the starting sign: Mesha for fire signs, Makara for earth signs, Tula for air signs and Karka for water signs. For example, Saturn at 21.9023° Dhanu is in the 7th part of Dhanu; Dhanu is a fire sign, so count seven signs from Mesha to reach Tula. Saturn's navamsa sign is Tula, where it is exalted. The calculator does this for every planet and for your ascendant.
What is the Navamsa Lagna?
The Navamsa Lagna is the navamsa sign of your ascendant. The houses of the D9 are counted from it. Because the ascendant crosses a navamsa in about 13 minutes, the result shows for how many minutes earlier and later your Navamsa Lagna would stay the same.
What is a vargottama planet?
A planet is vargottama when it is in the same sign in the birth chart (D1) and the navamsa (D9). This happens when it sits in the first navamsa of a movable sign, the middle (5th) navamsa of a fixed sign or the last navamsa of a dual sign. The result lists your vargottama planets and says whether your Lagna is vargottama.
What does exalted or debilitated in the navamsa mean?
A planet in its sign of exaltation in the D9 is called exalted in the navamsa, and one in its sign of debilitation is called debilitated there. Many astrologers weigh this alongside the planet's state in the birth chart. The calculator marks it for the Sun to Saturn; how much it changes a reading is a question for an astrologer.
Why does another calculator show a different navamsa?
The most common reason is the birth time: a few minutes can move the Navamsa Lagna to the next sign and renumber every D9 house. Another is the ayanamsa: software that uses a different one, such as KP or Raman, shifts every planet slightly, which matters for a planet near the edge of a navamsa. The result tells you when your chart has a placement that close.
Do I need my exact birth time?
Yes. The planets' navamsa signs rarely change over a few minutes, apart from the Moon near an edge, but the Navamsa Lagna changes about every 13 minutes, and every D9 house is counted from it. Use the time on your birth certificate if you have it.
Are my birth details saved?
Your details are used only to calculate the result. They are not saved to an account or profile, and they are never added to the page address or sent to analytics.
