Cast your Saptamsa (D7), the children-and-progeny divisional chart of Vedic astrology, from date, time, and place of birth. The tool computes your D7 Lagna with a birth-time-confidence check, every planet’s D7 sign and house with its BPHS division name, and renders the chart in North or South Indian style. Uses the sidereal Lahiri ayanamsa, the same engine as our Kundli.
100% private - the D7 calculation runs entirely in your browser. No birth data sent anywhere.
Supports 1900 onwards for better calculation reliability.
Birth time matters here: your D7 Lagna changes about every 17 minutes on average - far faster than the ~2-hour D1 Lagna - so even a few minutes can shift the whole D7 house framework.

The Saptamsa - also spelled Saptamsha - is the seventh 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 Saptamsa to sons and grandsons: children, progeny, and by extension the continuity of the family line.
Like every varga, the D7 is a derived chart: it takes each planet’s exact sidereal longitude from the birth chart and re-maps it by finer divisions of about 4.29 deg. Nothing new is observed in the sky; the varga re-reads the same positions at higher resolution, which is why precise birth details matter more here than in the D1.
Each 30-deg sign is divided into seven parts of 30/7 deg. For an odd sign (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) the seven parts map to seven consecutive signs starting from the sign itself; for an even sign (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces) the count starts from the seventh sign counted from it. Note that this is a third distinct start-sign convention - the Navamsa keys on movable/fixed/dual and the Dasamsa counts even signs from the 9th - each varga carries its own rule.
The same BPHS passage names the seven divisions after seven liquids. Odd signs read them in forward order, even signs in reverse:
| Part | Degrees in sign | Odd sign name | Even sign name |
|---|---|---|---|
| 1 | 0.00 - 4.29 deg | Kshara | Suddha Jala |
| 2 | 4.29 - 8.57 deg | Ksheera | Madhya |
| 3 | 8.57 - 12.86 deg | Dadhi | Ikshu Rasa |
| 4 | 12.86 - 17.14 deg | Ghrita | Ghrita |
| 5 | 17.14 - 21.43 deg | Ikshu Rasa | Dadhi |
| 6 | 21.43 - 25.71 deg | Madhya | Ksheera |
| 7 | 25.71 - 30.00 deg | Suddha Jala | Kshara |
Methods note: the consulted BPHS translation prints the sixth name “Madhya”; several traditions render it Madya (wine). We keep the text’s spelling and disclose the variant rather than silently choosing.
The ascendant crosses one saptamsa division in roughly 17 minutes of clock time on average - slower than the Dasamsa’s ~12 minutes but still 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 D7 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 4.29-deg division that margin covers roughly one placement in seven. Any planet within 0.3 deg of a division edge is flagged in the table rather than presented as certain.
Practitioner sources commonly look at the D7 Lagna and its lord, the 5th house from the D7 Lagna (the house classically associated with children), and Jupiter, the classical significator (karaka) of progeny, in the D7. The chart is read together with the D1’s own 5th house, and practitioners hold that the varga refines the birth chart rather than overriding it - the same relationship the Navamsa (D9) has with marriage significations and the Dasamsa (D10) with career.
All of this is descriptive tradition, not prediction. This page deliberately draws a hard line: fertility and family planning are medical and personal matters, and no chart placement predicts them.
This version computes the D7 chart, houses (whole-sign from the D7 Lagna), the BPHS division names, and the birth-time-confidence checks. It does not compute the Bheeja/Kshetra Sphuta (classical fertility points - deliberately out of scope), does not count or time children, and ships no predictions and no remedies.
The Saptamsa is the seventh divisional chart (varga) of Vedic astrology: each 30-deg sign is divided into seven parts of about 4.29 deg, and every planet is re-mapped to a new sign based on which part it occupies. The classical varga-use verse assigns this chart to sons and grandsons - children and progeny - which is why it is often called the children chart. It is read alongside the birth chart (D1), not instead of it.
Each sign is split into seven parts of 30/7 deg. For an odd sign (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) the seven parts map to seven consecutive signs starting from that sign itself; for an even sign they start from the seventh sign counted from it. This is the rule in the Brihat Parashara Hora Shastra, and this tool's output was cross-checked against two independent live calculators.
The Brihat Parashara Hora Shastra names the seven saptamsa divisions after seven liquids: Kshara, Ksheera (milk), Dadhi (curd), Ghrita (ghee), Ikshu Rasa (sugarcane juice), Madhya, and Suddha Jala (pure water). Odd signs read the list in that order; even signs read it in reverse. The consulted translation prints the sixth name as Madhya; several traditions render it Madya (wine) - we keep the text's spelling and disclose the variant. Traditional sources treat these as descriptive flavours of the divisions.
The 5th house of the D1 is one house among twelve in the natal chart and is classically associated with children; the Saptamsa is an entire twelve-sign chart derived from finer divisions, classically read for the same domain at higher resolution. Practitioners read the two together - the varga refines the birth chart and cannot promise what the birth chart does not.
The ascendant moves through one saptamsa division in roughly 17 minutes of clock time on average (it varies by rising sign and latitude), so an error of some minutes in birth time can shift the whole D7 house framework. This tool reports how many minutes your entered time sits from the nearest D7 Lagna boundary. A planet within about 0.3 deg of a division edge is flagged too.
The planet keeps the same sign context in both charts. It is not rare: every sign maps exactly one of its seven parts back to itself, so about 1 in 7 placements lands in its own D1 sign by pure arithmetic. (The classical term vargottama refers to the D1/D9 correspondence, not to D7.)
No. It computes the classical D7 chart and describes what traditional sources say the chart is read for. It makes no predictions about having children, and it offers no remedies. Fertility and family planning are medical and deeply personal matters - please rely on doctors and your own judgment, not chart placements.
This page is the canonical surface for these terms: Saptamsa, Saptamsha, Sapthamsa, and D7 chart. They all refer to the seventh divisional chart described above.
