How Bhagya.ai Calculates Kundli

Bhagya.ai uses the birth details you provide to calculate a Kundli, then explains available chart data in plain language. Calculation facts, traditional interpretation, and AI-assisted wording are kept distinct so that a result is easier to inspect and use responsibly.

What calculation method does Bhagya use?

For Bhagya Standard Detailed Kundli reports, the documented basis is a sidereal zodiac with Lahiri ayanamsa, Swiss Ephemeris planetary positions, whole-sign natal houses, and True Node for Rahu and Ketu. Mean Node can appear as a labelled reference option rather than silently changing the standard result.

The calculation record includes the method and version, IANA time zone and UTC offset, daylight-saving status, coordinates when available, and other provenance needed to understand a result or compare it with another platform.

How does Bhagya generate a Kundli?

The flow starts with the available birth details. Exact birth time and a verified birthplace matter most for Lagna, houses, divisional charts, and time-sensitive interpretations.

1. Validate the supplied birth date, time when available, and birthplace
2. Resolve location, time zone, and historical time conversion where data is available
3. Calculate planetary positions and the Ascendant from the documented method
4. Derive Rashi, Nakshatra, Pada, houses, and supported Dasha timing
5. Record calculation settings before interpretation is written

How does Bhagya calculate Kundli Milan?

Kundli Milan compares two birth charts through the traditional Ashtakoot system. It shows the eight Kootas and their combined 36 Guna score as one part of a wider compatibility reading.

• Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, and Nadi
• Mangal Dosha context using the documented rule set and relevant chart references
• D9 (Navamsa) and the natal chart as supporting context when the required birth time is reliable
• A non-deterministic explanation that keeps consent, communication, values, and real-life context central

Which classical framework and Dasha does Bhagya reference?

Bhagya's educational interpretation references widely known Jyotisha traditions associated with Brihat Parashara Hora Shastra, Phaladeepika, and Saravali. These texts represent classical source traditions, not a claim that every school agrees on one rule or conclusion.

The standard timing reference is Vimshottari Dasha, derived from the Moon's Nakshatra. D9 (Navamsa) can refine marriage interpretation, but it does not override the D1 birth chart, Ashtakoot score, consent, or lived relationship context. A missing or approximate birth time limits Lagna-, house-, and divisional-chart conclusions.

How does Bhagya use AI?

AI helps explain already calculated chart data and organize traditional interpretations in clear language. It does not replace astronomical calculation and may make explanatory mistakes, so Bhagya should show supporting chart facts and label general content separately from personal chart results.

Accuracy and limitations

Calculation output depends on the supplied birth details and documented method. An unknown or approximate birth time can change Lagna, house, divisional-chart, Nakshatra-boundary, and Dasha conclusions; Bhagya should show this limitation instead of presenting time-sensitive conclusions as certain.

Astrology is interpretive. Bhagya does not claim to predict exact events, and its guidance is not medical, legal, financial, mental-health, or emergency advice.

Calculation settings and provenance

This group identifies the technical basis Bhagya documents for a report and the independent ephemeris documentation used to describe the calculation reference.

• Lahiri ayanamsha: Bhagya Standard Detailed Kundli uses a sidereal zodiac with Lahiri as the documented default.
• Swiss Ephemeris: planetary positions use the documented ephemeris reference rather than AI-generated positions.
• Whole-sign houses: Bhagya Standard records whole-sign natal houses; any Bhava Chalit comparison must remain explicitly labelled.
• Node mode: True Node is the documented standard for Rahu and Ketu, while Mean Node is a labelled reference option.
• Time conversion: the record includes IANA time zone, UTC offset, daylight-saving status, and location context when available.
• Calculation provenance: report settings identify the inputs, method, version, coordinates when available, and report timestamp needed for comparison.

AI interpretation limits and traditional context

This group separates calculated chart facts from traditional interpretation and the AI wording used to explain them.

• AI explains available calculated chart data; it does not calculate planetary positions or guarantee events.
• Birth-detail uncertainty, especially time and location, must remain visible where it can affect Lagna, houses, divisions, Nakshatra boundaries, or Dasha timing.
• Traditional sources document historical and cultural frameworks. They are not scientific proof and do not replace medical, legal, financial, mental-health, or emergency advice.
