Navamsa / D9 sign calculator
Enter a planet’s sidereal sign and degree to find its Navamsa sign. Repeat for each planet to build the sign placements of a D9 chart. This is a position lookup, rather than a full birth-data chart generator.
Find a planet’s D9 sign
Use a sidereal sign and degree from your birth chart, not a tropical position. Repeat for each planet. For the D9 ascendant, use the exact sidereal ascendant degree.
Calculated on your device. This lookup does not upload the position you enter.
How is a Navamsa sign calculated?
Each 30° sign is divided into nine parts of 3°20′. Movable signs start their Navamsa sequence in the same sign; fixed signs start in the ninth sign from themselves; dual signs start in the fifth. Continue forward one sign for each part. The equivalent calculation multiplies the full sidereal longitude by nine and wraps it around the 360° zodiac.
For example, Aries 0° maps to Aries in D9; Aries 3°20′ maps to Taurus. Taurus 0° starts in Capricorn. Gemini 0° starts in Libra. This tool uses the entered position directly, with no assumed 15° midpoint.
The D9 ascendant needs an exact position
A natal ascendant sign alone is insufficient. Enter its exact sidereal degree to calculate the D9 ascendant sign. D9 houses can then be counted from that sign in a whole-sign chart. With an unknown or rounded birth time, do not treat those houses as certain.
Read D9 alongside the birth chart
In Jyotish, Navamsa is traditionally interpreted alongside the D1 chart for planetary dignity and partnership themes. It does not establish a marriage date or guarantee a relationship outcome. Read the D9 guide.
