Saptamsa Chart (D7) — Children & Progeny
D7 is the progeny divisional chart: children, procreative promise, and the legacy your chart carries — read from your birth details.
The Saptamsa (D7) is the varga Vedic astrology reads for children and progeny. Each 30° rashi is divided into seven parts of 4°17' each, and every planet is re-mapped into a fresh twelve-house chart focused on the 5th-house themes of the birth chart — santan (children), procreative capacity, and the creative work you leave behind. Where the D1 5th house names the broad promise of progeny, the Saptamsa is the delivery chart: it shows how that promise matures, the timing supported by dasha, and which grahas help or delay it.
What Saptamsa Shows
- Prospect of children — The D7 lagna, its lord, and the 5th house of the Saptamsa together indicate the strength of the progeny signal already present in the natal 5th house.
- Jupiter — the karaka of children — Jupiter's dignity and placement in D7 is read first: strong and well-placed supports santan sukh; afflicted or debilitated points to delay and a matched upay.
- Timing of progeny — Read the Saptamsa alongside Vimshottari dasha — the mahadasha or antardasha of the 5th lord and Jupiter typically activate the progeny yoga.
- Creative legacy — Beyond biological children, the 5th house governs poorva-punya and creation, so D7 also colours the works, students, and legacy a chart is capable of producing.
- Vargottama planets — A planet in the same rashi in D1 and D7 gains great strength for progeny matters — a supportive signal the engine flags on your chart.
D1 vs D7 — Two Layers of Progeny
The natal 5th house (D1, 5th from lagna) is one signal — it shows the surface promise of children and creativity. D7 is a SECOND chart focused only on progeny; every planet's Saptamsa position is independent of its D1 position.
A 5th house strong in D1 but weak in D7 can mean the promise exists yet asks for effort, remedy, and the right dasha before it matures. Strong in both, supported by a well-placed Jupiter, is the classical signature of easy santan sukh.
Frequently Asked Questions
What is the Saptamsa chart?
Saptamsa (सप्तांश, literally 'seventh part') is the D7 divisional chart in Vedic astrology. Each 30° rashi is divided into 7 parts of 4°17' each, each mapped to a rashi, producing a second twelve-house chart that focuses specifically on children, progeny, and creative legacy.
Why is Saptamsa specifically about children?
Brihat Parashara Hora Shastra maps each varga to a life domain: D9 = marriage, D10 = career, D7 = children, D12 = parents. The number 7 and the 7th division correspond to the progeny significations already carried by the natal 5th house, so the D7 chart amplifies that signal.
Which planet matters most in the D7?
Jupiter (Guru) is the natural karaka of children, so its dignity and placement in the Saptamsa is read first, together with the 5th house of D7 and its lord. The Ishvaram engine reports each planet's D7 dignity so you can see this at a glance.
Does the Saptamsa need my exact birth time?
Yes. Each D7 division spans only 4°17' of a rashi, so the D7 lagna changes roughly every few minutes. An accurate birth time is essential for a meaningful Saptamsa reading — enter it in the calculator for the correct lagna.
How do I get my Saptamsa chart from Ishvaram?
Enter your date, exact time, and place of birth in the calculator above. The Ishvaram engine computes the D7 layout — planets, varga lagna, and per-planet dignity — from the Swiss Ephemeris, so you can read progeny and legacy without calculating the varga by hand.
