Trimsamsa Chart (D30) — Misfortunes & Health
D30 is the adversity divisional chart: health weak spots, hidden troubles, and the inner strength your chart carries — read from your birth details.
The Trimsamsa (D30) is the varga Vedic astrology reads for misfortunes, arishta (adversity), and inner character. Unlike most vargas, its parts are unequal: each rashi is divided into five segments ruled by Mars, Saturn, Jupiter, Mercury, and Venus, with no lunar or solar rulership — a construction that highlights struggle and testing. The D30 shows health vulnerabilities, the kinds of difficulty a chart is prone to, and, crucially, the moral fibre and resilience a person can draw on. Where the D1 6th and 8th houses name the broad promise of adversity, the Trimsamsa details where it concentrates and how it can be worked with.
What Trimsamsa Shows
- Areas of adversity — The D30 lagna, its lord, and the malefic vs benefic rulership of key placements indicate the domains where difficulty and testing concentrate.
- Health vulnerabilities — Planets in weak dignity in D30, read with the 6th and 8th houses, point to the constitutional weak spots a chart carries and where preventive care helps.
- Malefic vs benefic segments — The Mars/Saturn segments carry harsher testing while the Jupiter/Mercury/Venus segments soften it — the balance shapes how adversity is experienced.
- Moral character and resilience — Classically the Trimsamsa also reveals sheela (character) and the inner strength available to meet hardship — not only the hardship itself.
- Where an upay helps — A debilitated or malefic-ruled placement in D30 is exactly the kind of signal a targeted remedy is designed for, timed to the running dasha.

Frequently Asked Questions
What is the Trimsamsa chart?
Trimsamsa (त्रिंशांश, 'thirtieth part') is the D30 divisional chart in Vedic astrology. Each rashi is divided into five unequal parts ruled by Mars, Saturn, Jupiter, Mercury, and Venus, producing a chart that focuses specifically on misfortunes, health, and inner character.
Why does the Trimsamsa use unequal divisions?
The D30 uses five unequal planetary segments per rashi — Mars, Saturn, Jupiter, Mercury, Venus — with no Sun or Moon rulership. Brihat Parashara Hora Shastra designs it this way so the chart emphasises the tapa (testing) and character themes rather than smooth significations.
Is the D30 only about bad luck?
No. While the Trimsamsa reveals adversity, disease tendencies, and weak spots, it equally reveals sheela — moral character and the inner strength a person can draw on. It is read as a resilience chart, not only a misfortune chart.
Does the D30 need my exact birth time?
Yes. Each D30 segment spans only a few degrees of a rashi, so the D30 lagna is time-sensitive. Enter an accurate birth time in the calculator so the varga lagna and placements are correct.
How do I get my Trimsamsa chart from Ishvaram?
Enter your date, exact time, and place of birth in the calculator above. The Ishvaram engine computes the D30 layout — planets, varga lagna, and per-planet dignity — from the Swiss Ephemeris, so you can read adversity and resilience without calculating the varga by hand.
