Navamsa Chart (D9) Calculator
The Navamsa, or D9, divides each sign into nine equal parts. It is the most widely used divisional chart and is often read next to the main birth chart.
Before you calculate
The Navamsa needs the same three details as the main Kundli: the date of birth, the local clock time and the place. Use the time from a birth certificate or hospital record if you have one, because family memory is often rounded to the nearest half hour. Pick the city from the list, or open the manual section and type the latitude, longitude and time zone yourself. The time zone matters as much as the coordinates, since it decides how the clock time is turned into universal time, including any daylight saving that applied on that date.
What the Navamsa is
Each zodiac sign spans 30 degrees. The Navamsa splits that span into nine portions of 3°20′ each, and every portion is assigned to a sign. A planet's Navamsa sign is the sign of the portion it falls in. Repeating this for the ascendant and all nine grahas gives a complete second chart, known as the D9.
In traditional practice the Navamsa is associated with marriage, partnership and dharma, and it is also used to judge how strong a planet is overall. A planet that holds the same sign in both charts is called vargottama and is usually given extra weight.
How to read the result
The table lists the ascendant and each planet with its Navamsa sign and the degree within the Navamsa. Houses are counted from the Navamsa ascendant as whole signs, so the sign of the D9 ascendant becomes the first house of this chart.
Because each Navamsa portion is only 3°20′ wide, the D9 ascendant can change with a birth time difference of around ten to fifteen minutes. Planet placements are steadier, but a planet close to the edge of a portion can move to the next sign with a small change in time. Compare the result with the main Kundli rather than reading it alone.
Calculation settings
Positions are sidereal with the Lahiri ayanamsa, and Rahu and Ketu are true nodes. The Navamsa uses the common Parashari scheme in which the count of nine portions starts from a movable, fixed or dual sign depending on the element of the sign. Houses are whole signs from the Navamsa ascendant.
If you would like to see other divisions, such as the Dasamsa (D10) for career or the Saptamsa (D7) for children, use the divisional charts tool. These results have not yet been checked against published reference charts.
