Janam Kundli: What a Vedic Birth Chart Actually Contains

The three inputs, and why the time matters most

Date of birth fixes where the slow planets are. Place of birth fixes the geography the sky is measured against. Birth time fixes the ascendant — and the ascendant is what turns a set of planetary positions into a chart about a specific person.

The ascendant changes sign roughly every two hours, so an error of an hour can move it. When it moves, every house moves with it, every house lord changes, and the chart describes someone else. This is why an honest reading asks how confident you are about your birth time and changes its method if the answer is 'not very' — falling back on the Moon chart, which is far more forgiving of an imprecise time.

What the chart is made of

Nine grahas: the Sun and Moon, the five visible planets, and Rahu and Ketu, the two shadow points where the Moon's orbit crosses the ecliptic. Twelve rashis, the sidereal signs, each 30° wide. Twelve bhavas, the houses, counted from the ascendant. And twenty-seven nakshatras, each 13°20′ wide, dividing the same circle a second way.

From those, everything else is derived: the yogas (specific planetary combinations), the doshas (specific afflictions), the divisional charts such as Navamsa (D9) for marriage and Dashamsa (D10) for career, and the Vimshottari dasha, the timeline that says when a chart's potential becomes active.

North Indian and South Indian charts are the same chart

In the North Indian style the diagram is a square with both diagonals and an inner diamond, the houses are fixed in position, and the sign numbers move. The first house is always the top-centre diamond. In the South Indian style the signs are fixed in a 4×3 grid and the ascendant is marked, so the houses move instead.

They contain identical information. Which one a chart is drawn in is regional convention, not a difference in astrology. VedikPatrika draws the North Indian style, which is standard across most of northern India.

What a kundli can and cannot tell you

A kundli is a calculation. The positions in it are astronomy and are exactly as accurate as the ephemeris and the birth details allow. What is drawn from those positions is interpretation within a traditional system — a body of practice with its own internal logic and a long history, but not an empirically established science, and it should be understood that way.

VedikPatrika will not predict death, serious illness, accidents, divorce as a certainty, or legal outcomes, and offers no medical, legal or investment advice. That is a fixed editorial rule and not a matter of tone. Where a chart shows difficulty, a reading should say so honestly and say what can be done about it.

Common questions

Can I get a kundli without knowing my birth time?

Yes, with a stated limitation. Without a birth time the ascendant cannot be fixed, so the reading is built on the Moon chart — the Moon's sign, its nakshatra, and the dasha sequence that follows. Everything else is calculated as normal. What you lose is house-based analysis, which is a real loss but not a total one.

Why is my Vedic sign different from my Western sign?

Vedic astrology uses the sidereal zodiac, measured against the fixed stars; Western astrology uses the tropical zodiac, measured from the equinox. The two have drifted about 24° apart, so a Vedic sign is frequently one behind the Western one. Both are internally consistent; they simply measure from different origins.

What is the difference between a kundli and a horoscope?

In Indian usage 'kundli' means the birth chart itself — the diagram and the calculations. 'Horoscope' in everyday English usually means the daily sun-sign column, which is a different and much shallower thing. A rashifal, calculated from the Moon sign, sits between the two.
