Draw your navamsa (D9) beside your birth chart

Last updated 25 October 2026

Enter your date and time of birth, and your place for the navamsa lagna, to draw the D9 chart next to your birth chart with every planet’s navamsa sign. Underneath: how the ninth division is counted, how an astrologer weighs it against the birth chart, and where it tends to be overread.

How the navamsa is worked out

Navamsa means “ninth part”. Every sign of 30° is split into nine segments of 3°20′, and each segment is assigned a sign of its own. The count starts in a different place depending on the sign’s quality: a movable sign starts from itself, a fixed sign from the ninth sign from it, and a dual sign from the fifth. The result is tidy: the 108 navamsas of the zodiac run through the twelve signs nine times in order, and each one coincides with one nakshatra pada.

The calculator takes your date of birth, time and UTC offset, and optionally a city or latitude and longitude. It computes the sidereal (Lahiri) positions of the Sun, the Moon, the five visible planets and the two nodes, and, when a place is given, the lagna. It then draws the navamsa and the birth chart side by side in North or South Indian style and lists each planet’s birth-chart sign, degree, nakshatra pada and navamsa sign, marking any that are vargottama. Without a time, it shows how each planet’s navamsa changed through the day instead.

Reading the D9 together with the birth chart

The working rule most Parashari astrologers follow is that the birth chart (D1) shows what a life promises and the navamsa shows how well that promise holds up. A planet that looks strong in the D1 but lands in its sign of debilitation in the D9 is read more cautiously; one that looks modest in the D1 but is exalted or in its own sign in the D9 is often said to gain strength over time. Vargottama planets, the same sign in both charts, are read as reliable and consistent.

For marriage, the astrologer usually looks at the seventh house and its lord in both charts, at Venus and Jupiter, the planets tradition links with the spouse, and at the seventh house of the navamsa counted from the navamsa lagna. For inner strength and the direction a person grows into, the navamsa lagna and its lord and the D9 position of the lagna lord carry weight. None of this replaces the D1: a reader who builds a whole interpretation from the D9 has skipped the chart that the D9 is meant to refine.

Where people overread the navamsa

The navamsa invites overconfidence because it seems to answer intimate questions directly. Three habits are worth avoiding, whether you are the client or the reader.

• Trusting a D9 lagna the birth time cannot support. A navamsa of the lagna lasts around thirteen minutes on average. If the birth time is rounded, the D9 lagna and every house counted from it may be wrong.
• Turning one placement into a verdict. A single planet in a difficult navamsa sign is a factor to weigh, not a description of a future spouse or a marriage.
• Using it to make the decision. A chart can help frame a conversation about a relationship. The decision itself belongs to the people involved, with a qualified counsellor or other professional where there are real concerns.

Questions to ask your astrologer about your navamsa

• Is my birth time accurate enough for you to use the navamsa lagna, or are you reading only planet signs?
• Which of my planets gain or lose strength between the D1 and the D9, and how does that change your reading?
• Are any of my planets vargottama, and what weight do you give that?
• For marriage, what are you reading from the D1 and what from the D9?
• Does the navamsa change how you see my current dasha lord?
• Do you use pushkar navamsas, and do any of my planets fall in one?

If a match is part of your question, our guide to the kundli matching consultation explains what a careful astrologer covers beyond the points score.

Pushkar navamsas and pushkar bhaga by sign

Two of the nine navamsas in each sign are called pushkar (“nourishing”) navamsas, and one degree in each sign is the pushkar bhaga. Astrologers who use them treat a planet placed there as supported. The pairs are the same for the three signs of an element. The calculator checks the lagna and the seven planets against both, using the pushkar bhaga degrees given in Jataka Parijata and marking a body within 1° of that degree; Rahu and Ketu are not checked. A second list of bhaga degrees found in modern books is shown for comparison.
