"D" stands for division, and 9 refers to each zodiac sign being split into 9 equal parts (Navamsas) — one of several "divisional" or "harmonic" charts used in Vedic astrology (D9, D10, D12, and others each divide differently).

What does "Vargottama" mean?

When a planet occupies the same sign in both the D1 (main) chart and the D9 (Navamsa) chart — traditionally considered a source of added strength for that planet.

Why do movable, fixed, and dual signs use different counting rules?

This is a real, classical rule from Vedic astrology's divisional-chart methodology, not a simplification this tool introduces — each of the 3 sign categories (movable/fixed/dual) has its own traditional Navamsa-counting convention.

Does the Navamsa chart replace my main birth chart?

No — it's a complementary, more detailed chart traditionally read alongside the D1 chart, not a replacement for it. See this site's Kundali Birth Chart Calculator for your D1 positions.

Is the Navamsa chart mainly used for marriage compatibility?

It's traditionally emphasized for marriage and relationship analysis, but also used more broadly to examine a planet's underlying strength and one's spiritual inclinations — its use isn't limited to marriage topics alone.

Does this tool show my D9 Ascendant's houses?

No — it shows the D9 Ascendant sign and each Graha's D9 sign only, not a full house-by-house divisional chart layout.

How accurate are the planetary positions used here?

Built on the same astronomy-engine-based positions as this site's Kundali Birth Chart Calculator, accurate to about 1 arcminute, with the Navamsa formula itself separately verified against 2 independent published worked examples.

Are there other divisional charts besides D9?

Yes — Vedic astrology traditionally uses many divisional charts (D2, D3, D7, D10, D12, D30, and others), each highlighting a different life area; this tool currently computes only the D9 (Navamsa), the most widely used one.

About the Navamsa (D9) Chart Calculator

Computes your Navamsa (D9) divisional chart — each of the 9 Grahas' D9 sign, compared against their main D1 Rashi position.

How to use it

Enter your birth location, date, and time.
Read your Navamsa Ascendant at the top.
Compare each Graha's D1 (main chart) sign against its D9 (Navamsa) sign below.
Look for "Vargottama" — when a planet lands in the same sign in both charts, traditionally considered a source of added strength.

Formula

Each 30° Rashi (zodiac sign) splits into 9 equal 3°20' divisions (Navamsas). Which sign a given division maps to follows a classical rule based on the Rashi's nature: movable signs (Aries/Cancer/Libra/Capricorn) count divisions starting from themselves; fixed signs (Taurus/Leo/Scorpio/Aquarius) start counting from the 9th sign from themselves; dual signs (Gemini/Virgo/Sagittarius/Pisces) start from the 5th sign from themselves.

Worked example

A planet at 28° Cancer (a movable sign) falls in its 9th and final Navamsa division, landing in Pisces — since Cancer's Navamsa count starts from Cancer itself, and the 9th sign counted forward from Cancer is Pisces.

Navamsa counting rule by Rashi nature

Navamsa counting rule by Rashi nature
Rashi nature	Signs	Navamsa count starts from
Movable (Chara)	Mesha, Karka, Tula, Makara	The same sign
Fixed (Sthira)	Vrishabha, Simha, Vrishchika, Kumbha	The 9th sign from itself
Dual (Dwiswabhava)	Mithuna, Kanya, Dhanu, Meena	The 5th sign from itself

Interpreting your result

Verified against 2 independently-published worked examples before shipping: 28° Cancer (a movable sign) correctly resolved to Pisces; Taurus 17° (a fixed sign) correctly resolved to Navamsa #6 starting from Capricorn, matching each source's own stated intermediate result exactly. This shows D9 sign positions only, not a full interpretive reading, house placements, or divisional-chart-specific strength analysis (Vimshopaka Bala) — consult a qualified astrologer for that.

Recommendations

• See this site's Kundali Birth Chart Calculator first for your D1 (main chart) positions — this tool shows the same 9 Grahas' D9 positions alongside them for direct comparison.
