Birth Chart Report

See the core facts of your birth chart, computed from your date, time and place of birth: the Lagna (the rising sign) and its lord, the Moon’s sign and nakshatra, and for each of the twelve houses the sign on it, the planet that rules that sign, and the house and sign where that planet sits. Uses the sidereal Lahiri ayanamsa and whole-sign houses, the same engine as our Kundli.

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

The birth time sets the Lagna and with it every house, so an exact time matters here.

What a house lord is, and why its placement is shown

With whole-sign houses, the sign rising at birth is the 1st house and each following sign is the next house. Every sign has a ruling planet, so every house has a lord: the planet that rules the sign on it. The Lagna lord is the lord of the 1st house.

Classical texts take each house lord through the twelve houses: Brihat Parasara Hora Shastra, Vol. I, chapter 24, gives a verse for the lord of every house in every house. That is why the table shows where each lord sits. The page states the placement and stops; the report adds the verse, where one gives a usable line, with its source.

Why the birth time matters

The Lagna is set by the birth time, and the Lagna sets every house: the rising sign moves on by about one sign every two hours, so a wrong time can move every house and every house lord shown above. The planets’ signs change far more slowly. The report’s birth-time section shows which of its classifications hold if the time is off by up to 5 minutes either way, and marks each item that rests on one that does not.

What this page and the report leave out

Both stay with the birth chart. The divisional charts are on the site’s free Navamsa calculator and its other varga pages, the combinations a chart forms on the free yoga calculators, and the running periods on the Vimshottari Dasha calculator. The report states conditions and the significations the texts attach to them; it makes no claim about events and gives no remedies.

Frequently Asked Questions

What does the free part of this page show?

From your date, time and place of birth it computes the Lagna (the rising sign) and its lord, the Moon's sign and nakshatra, and for each of the twelve houses the sign on it, the planet that rules that sign, and the house and sign where that ruler sits. Each is a condition of the birth chart (the D1), stated as a fact, on the Lahiri ayanamsa with whole-sign houses.

What does the Birth Chart Report add?

A cited PDF of the whole birth chart: the Lagna and its lord, one section for each of the twelve houses and each of the nine planets, with dignity, graha drishti, associations and combustion where they apply, the Moon's sign, how the factors sit together, the full tables, and which classifications hold if the birth time is off by up to 5 minutes either way. Where this report's content rules include a line for a condition, the line gives what a named classical text attaches to it, with the chapter and verse; any other condition is stated on its own.

What does the report leave out?

It states chart conditions and the significations named classical texts attach to them, with sources. It does not predict outcomes or events; it does not prescribe remedies or give personal advice; and it covers no divisional chart, yoga, Shadbala figure or period. It also leaves out what the texts say of health, longevity, conduct, marriage and children's fortunes.

Why does it need an exact birth time?

The birth time sets the Lagna, and the Lagna sets every house: the rising sign moves on by about one sign every two hours, so a wrong time can move every house and every house lord shown here. The planets' signs change far more slowly. The report's birth-time section shows which of its classifications hold if the time is off by up to 5 minutes either way.

Which texts does the report cite?

Brihat Parasara Hora Shastra, Vol. I, and Saravali, Vols. I and II, in R. Santhanam's translations, and Phaladeepika in V. Subrahmanya Sastri's translation. Each line in the report was checked against a pinned copy of the edition it cites and carries its chapter and verse.

Is my birth data sent anywhere?

No. The chart is calculated in your browser, and the free facts on this page never leave it.
