Enter your birth date, recorded local time, and birthplace. OpenFate calculates a Lahiri sidereal, whole-sign Kundli. It includes the D-1 chart, lagna, nine grahas, Moon nakshatra, D-9 navamsa, D-10, Jaimini karakas, raw Sarvashtakavarga bindus, and Vimshottari periods when the birth time supports them. The basic chart is free. Calculation remains separate from optional AI interpretation.
A Vedic birth chart calculator converts your birth date, exact local time, and birthplace into a sidereal kundli. OpenFate uses the Lahiri ayanamsa and whole-sign houses, then derives the chart layers shown on the page from the same astronomical inputs.
The free chart keeps placements and derivations separate from interpretation. Its guide names the calculated anchors first. It then offers a familiar feeling, a possible benefit, a point of strain, and a next step. This is labeled OpenFate editorial reflection, so you can reject any lens that does not match reality.
The result includes the D-1 rashi chart, lagna, nine grahas, signs, houses, nakshatras, and padas. It also shows D-9 and D-10 divisional charts, Jaimini karakas, Sarvashtakavarga figures, and the Vimshottari dasha timeline supported by the recorded birth data.
With a reliable birth time, start with lagna and its lord. Then check the Moon sign and Moon nakshatra. Review D-1 placements before using D-9 for traditional commitment themes or D-10 for vocation themes. Treat the active dasha as a timing lens, not an event guarantee.
This calculator uses the sidereal zodiac with Lahiri ayanamsa. OpenFate's Western birth chart uses the tropical zodiac, so the same birth can produce different sign labels even though both calculations begin with the same date, time, and place.
Birthplace sets the timezone and geographic frame. The recorded minute affects lagna and other time-dependent layers. If time is unknown, even a planet's sign or nakshatra can cross a boundary during that civil date. The tool therefore labels retained placements as date-level estimates. It also suppresses unsupported house, varga, karaka, and dasha conclusions.
The calculator creates the chart from the recorded birth inputs and declared Jyotish settings. Optional AI can explain that stored output later. It does not supply a missing birth time, change a planetary placement, or make traditional symbols scientifically predictive.
Common questions about the free Vedic chart calculator and its computation basis.
Sidereal, using the Lahiri ayanamsa. Lahiri is a widely used Indian sidereal convention and this calculator's declared setting, not the only convention in Jyotish. Placements can therefore differ from both tropical charts and calculators using another ayanamsa.
They are divisional (varga) charts. In the interpretive scheme declared here, D-9 is used as a traditional lens for commitment and relationship themes, while D-10 is used for vocation and public-role themes. These are interpretive topics, not measured outcomes.
A reliable time is required for lagna, houses, varga lagnas, karakas, and the displayed dasha timeline. If time is unknown, the tool suppresses those layers and labels remaining sign and nakshatra output as date-level estimates because a boundary can occur within the day.
The free tool includes the calculated chart, derivations, declared heuristics, and a human-first guide grounded in selected chart anchors. The full reading adds AI synthesis, but it must preserve the same chart facts, use conditional language, and avoid invented scores or guaranteed outcomes.
Yes. You can create and inspect the basic Vedic chart without signing up. AI interpretation and follow-up questions are separate and may require an account and reading credits.
First check the birth time, coordinates, and time-zone conversion. Then compare the sidereal or tropical zodiac, ayanamsa, house system, node setting, ephemeris, and rounding rules. Align those inputs and settings before comparing charts.
