Dasamsa Chart Calculator (D10)

Cast your Dasamsa (D10), the career divisional chart of Vedic astrology, from date, time, and place of birth. The tool computes your D10 Lagna with a birth-time-confidence check, every planet’s D10 sign and house with its presiding digpala, and renders the chart in North or South Indian style. Uses the sidereal Lahiri ayanamsa, the same engine as our Kundli.

100% private - the D10 calculation runs entirely in your browser. No birth data sent anywhere.

Supports 1900 onwards for better calculation reliability.

Birth time matters most here: your D10 Lagna changes about every 12 minutes on average - far faster than the ~2-hour D1 Lagna - so even a few minutes can shift the whole career-chart house framework.

What is the Dasamsa (D10) chart?

The Dasamsa - also spelled Dashamsa, and known by the aliases Karmamsa and Swargamsa - is the tenth of the sixteen divisional charts (Shodasavarga) described in the Brihat Parashara Hora Shastra. Where the birth chart (D1) maps the whole life, each varga zooms into one domain, and the classical varga-use verse assigns the Dasamsa to power and position: career, profession, achievements, and standing in society.

Like every varga, the D10 is a derived chart: it takes each planet’s exact sidereal longitude from the birth chart and re-maps it by finer 3-deg divisions. Nothing new is observed in the sky; the varga re-reads the same positions at higher resolution, which is exactly why precise birth details matter more here than in the D1.

How the D10 is calculated (and its ten deities)

Each 30-deg sign is divided into ten parts of exactly 3 deg. For an odd sign (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) the ten parts map to ten consecutive signs starting from the sign itself; for an even sign (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces) the count starts from the ninth sign counted from it. A planet at 5 deg in Aries therefore lands in the second dasamsa of an odd sign - Taurus - while a planet at 5 deg in Taurus lands in the second dasamsa counted from Capricorn - Aquarius. Note the contrast with the Navamsa’s movable/fixed/dual rule: each varga has its own start-sign convention.

The same BPHS passage assigns each of the ten divisions a presiding digpala - a ruler of the directions. Odd signs read the ten in forward order, even signs in reverse:

PartDegrees in signOdd sign deityEven sign deity

718 - 21 degKuberaRakshasa
821 - 24 degIshanaYama
924 - 27 degBrahmaAgni
1027 - 30 degAnantaIndra

Methods note: the consulted BPHS translation names the fourth digpala “Rakshasa”; some traditions call this direction-ruler Nirriti. We keep the text’s naming and disclose the variant rather than silently choosing.

D10 Lagna and birth-time precision

The ascendant crosses one 3-deg dasamsa division in roughly 12 minutes of clock time on average - faster than the Navamsa’s ~13-14 minutes, and far faster than the roughly two hours the D1 Lagna spends in a sign. The exact interval varies with rising sign and latitude (oblique ascension), so instead of quoting only the average, this tool computes your chart’s distance to the nearest D10 Lagna boundary in minutes and says so plainly.

Planet placements have their own fragility: the engine’s typical precision is about 0.3 deg against observatory-grade ephemerides, and on a 3-deg division that margin covers roughly one placement in five. Any planet within 0.3 deg of a division edge is flagged in the table rather than presented as certain - a deliberately honest reading you should expect from any varga calculator.

How the D10 is classically read for career

Practitioner sources commonly describe this reading order: the D10 Lagna and its lord for the overall professional direction; the 10th house from the D10 Lagna and planets placed there for the karma itself; and the D10 positions of the Sun (authority), Saturn (work and service), and the D1 10th lord for how the natal career promise expresses - a sequence described by modern practitioner sources rather than fixed by the classical text itself. Modern Parashari-school sources also describe the Dasamsa as the chart of mahat phalam - the great results of one’s actions in society.

All of this is descriptive tradition, not prediction. A strong D10 placement is not a job offer, and a difficult one is not a verdict; practitioners weigh the whole chart, the running Vimshottari Dasha, and - above all - real-world context.

D10 vs the 10th house of the birth chart

The two are related but not interchangeable. The 10th house of the D1 is one of twelve houses in the natal chart and shows the direction of karma at sign-level resolution; the Dasamsa is a complete derived chart built from 3-deg divisions and is classically read for how that karma unfolds in the world. The working rule practitioners quote is that the varga refines the birth chart and cannot promise what the birth chart does not - the same relationship the Navamsa (D9) has with marriage significations, and the Raj Yoga combinations have with status in the D1.

What this version leaves out

This version computes the D10 chart, houses (whole-sign from the D10 Lagna), digpalas, and the birth-time-confidence checks. It does not compute varga-strength aggregates (Vimsopaka Bala, Shodasavarga classifications), does not read profession types from planet significations, and deliberately ships no career predictions and no remedies. Those aggregates are meaningful only across many vargas at once, and prediction is not this tool’s job.

Frequently Asked Questions

What is the Dasamsa (D10) chart?

The Dasamsa is the tenth divisional chart (varga) of Vedic astrology: each 30-deg sign is divided into ten parts of 3 deg, and every planet is re-mapped to a new sign based on which part it occupies. Classical texts assign this chart to karma - career, profession, power, and public standing - which is why it is often called the career chart. It is read alongside the birth chart (D1), not instead of it.

How is the D10 chart calculated?

Each sign is split into ten 3-deg parts. For an odd sign (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) the ten parts map to ten consecutive signs starting from that sign itself; for an even sign they start from the ninth sign counted from it. This is the rule given in the Brihat Parashara Hora Shastra and used by mainstream calculators; this tool's output was cross-checked against two independent live calculators.

Who are the digpalas shown next to each planet?

The Brihat Parashara Hora Shastra assigns each of the ten dasamsa divisions to one of the ten rulers of the directions (digpalas): Indra, Agni, Yama, Rakshasa, Varuna, Vayu, Kubera, Ishana, Brahma, and Ananta. Odd signs read the list in that order; even signs read it in reverse. Traditional sources treat the presiding digpala as a descriptive flavour of the division; this tool shows it as reference information, not as a judgment of the placement.

How is the D10 different from the 10th house of my birth chart?

The 10th house of the D1 is one house among twelve in the natal chart; the Dasamsa is an entire twelve-sign chart derived from finer 3-deg divisions. Practitioners classically read the D1 10th house for the direction of karma and the D10 for how it unfolds - but the D10 refines the D1, it does not override it, and both are read together.

Why does exact birth time matter so much for the D10?

The ascendant moves through one 3-deg dasamsa division in roughly 12 minutes of clock time on average (it varies by rising sign and latitude), so a small error in birth time can shift the whole D10 house framework. This tool reports how many minutes your entered time sits from the nearest D10 Lagna boundary, so you can see how robust your chart is. Planet signs are far less time-sensitive, but a planet within about 0.3 deg of a division edge is flagged too.

What does it mean if a planet is in the same sign in D1 and D10?

The planet keeps the same sign context in both charts, and some practitioners read that as continuity between the natal promise and its career expression. It is also not rare: every sign maps exactly one of its ten 3-deg parts back to itself, so about 1 in 10 placements lands in its own D1 sign by pure arithmetic. (The classical term vargottama refers to the D1/D9 correspondence, not to D10.)

Does this tool predict my career or suggest remedies?

No. It computes the classical D10 chart and describes what traditional sources say the chart is read for. It makes no predictions about jobs, promotions, or business outcomes, and it offers no remedies. Career decisions deserve real-world evidence and professional advice, not chart placements.
