A divisional chart (varga) magnifies one slice of the birth chart for one area of life. The Dasamsa takes each sign of the zodiac, cuts it into ten parts, and gives every part a sign of its own. The result is a full twelve-house chart whose subject is career, profession, status and public life. It does not replace the 10th house of your birth chart. It is read after it, as a second opinion.
How the D10 Is Built
Each 30° sign is divided into ten equal parts of 3°. Which sign each part lands in depends on whether the sign is odd or even:
| Sign type | Signs | Counting starts from |
|---|---|---|
| Odd | Aries, Gemini, Leo, Libra, Sagittarius, Aquarius | The same sign |
| Even | Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces | The 9th sign from it |
Count forward from that starting sign, one sign per 3° part. The classical source is the Dasamsa verse of the Brihat Parashara Hora Shastra, and Nyovah's engine implements exactly this rule. The same procedure applied to the ascendant's longitude gives the D10 lagna, which sets the house structure of the whole chart.
A worked example
Take a planet at 17°10' Taurus. At 3° per part it falls in part number 6 of ten. Taurus is an even sign, so counting starts from the 9th sign from Taurus, which is Capricorn. Part 1 is Capricorn, and counting on to part 6 lands on Gemini. That is the planet's D10 sign. (We ran this example through the engine's own D10 function rather than counting it by hand, and the result above is what it returns.)
What You Read in the D10
The order matters. The 10th house of the birth chart, its lord, and the planets and aspects on it come first. The D10 is then used to test and add detail:
- The D10 lagna and its lord. The sign rising in the D10 and the planet ruling it set the tone of the chart. Classically this planet is read as one of the indicators of the line of work.
- The D10 10th house and its occupants. The planets sitting in the career chart's own 10th house colour how the work shows up in public.
- Where your birth-chart 10th lord falls in the D10. A planet that carries the career promise in D1 is checked for where it lands under magnification.
What it does not do is name a job. Labour-market titles are facts about 2026, not facts about a chart. At most the D10 points at a kind of work and a way of working.
What Nyovah Reads From Your D10
The D10 is always computed for every chart, and Nyovah is specific about how it is used:
- The planet ruling the D10 lagna is one of four independent indicators in the career signature, alongside the 10th lord, the 10th lord's star lord, and the Amatyakaraka (Jaimini's career significator). The signature reports how many of the four point at the same planet. When they scatter, Nyovah says so instead of inventing a field.
- The planets in the D10 10th house are reported as context only. They do not count toward that agreement, so a crowded D10 10th cannot manufacture false certainty.
- In partnership and business reads, the D10 lagna and its 7th and 10th house occupants are included.
- For divisional charts Nyovah reports positions only: planet, sign, house. It does not grade a planet as strong or weak inside the D10.
How Sensitive Is the D10 to Birth Time?
The D10 lagna comes from the exact degree of the ascendant, and the ascendant moves around the zodiac once a day. We measured this with the same engine that builds your chart: running a full 24 hours of birth times minute by minute, the ascendant advanced 0.21° to 0.36° per minute, 0.25° on average, which is the familiar rule of thumb of about one degree every four minutes. One D10 division is 3° wide, so the D10 lagna changes sign roughly every 12 minutes of birth time.
Slow planets are far more stable. The Moon moves about 0.57° an hour in our engine, so even the Moon's D10 sign usually holds for several hours. The fragile part is the lagna. When it shifts, the whole house structure of the D10 shifts with it: which planet sits in the D10 10th, and which sign is the D10 lagna, can change within a quarter of an hour of birth time. If your birth time is rounded or approximate, treat D10 house placements as provisional and the planetary signs as the safer part.
The D10 Shows No Dates
Like the birth chart and every other divisional chart, the D10 is a static picture. It has no ages, no sequence and no calendar in it, so reading it more carefully will never produce a date. It can say how the career side of a chart is set up and whether the birth chart's statement holds under magnification. When it happens comes only from the Vimshottari dasha, which splits a life into planetary periods with exact start and end dates computed from the Moon's position at birth.
The usual order is therefore: find the planets that carry the matter in the birth chart, test them in the D10, then look up the dated periods those planets rule.
The Honest Limits
- It cannot pick your profession. At most it points at a kind of work and a way of working, and many charts do not name one field clearly.
- It cannot replace the birth chart. Reading the D10 first, or on its own, inverts the method.
- It cannot give timing. No chart can; dates come from the dasha.
- Above D9, accuracy depends on your birth time. Many practitioners limit practical reading to D1, D9 and D10 for exactly this reason.
The general rule and the missing piece: everything above is a rule you can apply to any chart. What no general article can give you is your own answer: which sign your D10 lagna is, which planets sit in your D10 10th house, and which dated dasha periods belong to the planets carrying your career. That comes from your exact birth date, time and place, and it is different for every chart.

Frequently Asked Questions
What is the Dasamsa (D10) chart?
The Dasamsa, or D10, is the divisional chart for career, profession, status and public life. It divides each 30 degree sign into ten parts of 3 degrees and assigns each part a sign, producing a full twelve-house chart. It is read after the birth chart as a second opinion on the 10th house, not instead of it.
How is the D10 calculated?
Find how far a planet sits into its sign and divide by 3 degrees to get its part number from 1 to 10. For odd signs (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) counting starts from the same sign. For even signs (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces) it starts from the 9th sign from it. Count forward by the part number to reach the D10 sign. The same method on the ascendant gives the D10 lagna.
Is the D10 more important than the 10th house?
No. The 10th house of the birth chart, its lord and the planets on it come first. The D10 is used to test and add detail to that statement. A D10 that contradicts a strong D1 10th house is a reason to qualify the reading, not to discard the birth chart.
What does the D10 lagna mean?
It is the sign rising in the career chart, and its ruling planet is classically read as one of the indicators of the line of work. In Nyovah it is one of four independent career indicators, together with the 10th lord, the 10th lord's star lord and the Amatyakaraka, and the signature reports whether they agree or scatter.
How accurate does my birth time need to be for the D10?
Very accurate. The ascendant advances about 0.25 degrees per minute in our engine, so a 3 degree D10 division passes in roughly 12 minutes. A birth time off by a quarter of an hour can change the D10 lagna. Planetary D10 signs are much more stable than the lagna, especially for slow planets.
Can the D10 tell me when I will change jobs?
No. The D10 is a static chart with no time axis. It can show how the career side of a chart is set up. The timing of a job change comes from the Vimshottari dasha, which gives exact dated periods, read together with transits as triggers.
Can the D10 tell me which profession to choose?
Not reliably. It can point toward a kind of work and a way of working, and when several classical indicators agree the pointer is stronger. Many charts do not name one field clearly, and a job title is a labour-market fact, not a chart fact.
Does Nyovah use the D10?
Yes. The D10 is computed for every chart. Its lagna lord is one of four independent indicators in the career signature, its 10th house occupants are shown as context only, and in business and partnership reads its 7th and 10th occupants are included. Nyovah reports planet, sign and house in the D10 and does not grade planets there.
