Calculation methodology

What happens between your birth details and your reading.

Anantrix separates astronomy, Vedic analysis and written interpretation. That makes it possible to explain what was calculated, reuse one chart consistently and state where the result becomes uncertain.

Calculation pipeline

1. Birth inputs

Date, local time, latitude, longitude and timezone are normalized on the server. The saved birth data remains the source used across the chart, dashboard and timeline.

2. Astronomical positions

The calculation engine derives planetary positions and applies the selected sidereal settings. Lahiri ayanamsha and whole-sign houses are the default for existing charts.

3. Vedic analysis

Chart rules derive houses, nakshatras, Yogas, doshas, Ashtakoota compatibility, Vimshottari periods and transit relationships from those positions.

4. Plain-language reading

A deterministic narrative layer converts the computed factors into direct, plain language. It uses the chart evidence already calculated rather than creating a different answer each time.

Why exact birth time matters

The ascendant moves quickly, so the birth time controls the house layout and every conclusion anchored to it. A small time difference can matter near a house or sign boundary. Moon-based calculations are usually less sensitive, but a birth near a nakshatra boundary can still produce two possible outcomes.

When you do not know the time, Anantrix uses the documented fallback shown in the form and limits the claims that depend on houses. For compatibility specifically, read the guide to what remains reliable without a birth time.

Consistency and updates

The chart calculation is versioned. Derived readings can be regenerated when calculation rules improve, while the original chart data remains the durable source. Time-sensitive pages recalculate current Dasha and transit context instead of treating an old generated paragraph as permanently current.

What this does not claim

Astrology is a cultural and reflective practice, not scientific certainty. Anantrix does not replace medical, legal, financial or mental-health professionals, and important decisions should not rest on an astrology result alone.
