How Kundli matching works with date, time and place of birth
Understand the birth details, Moon-based comparison and eight-factor results used by Astrogyana's free Kundli matching calculator.
An explanation of Astrogyana’s implemented methodology. Updated:
हिंदी में पढ़ेंStart with two recorded birth times
Prepare each person's birth date, local clock time and birthplace. The calculator resolves the location and its historical timezone before calculating the two charts. A current timezone offset is not necessarily the offset that applied on the birth date. Check the resolved city and coordinates, especially when several places share the same name.
Enter Person A in the traditional groom role and Person B in the traditional bride role used by the selected tables. These are calculation roles, independent of gender identity. Swapping A and B can change Varna, Vasya and Gana. The form does not request caste information.
What the free comparison actually calculates
The selected basic North Indian profile compares the two sidereal Moon positions through eight Ashtakoota factors, adding their points to a maximum of 36. Each factor is displayed separately with its explanation, so a single total does not hide where points were gained or lost.
Mars-house checks are displayed separately from the 36 points, using the ascendant and Moon as references. The results also provide both birth charts. The calculator does not select a wedding date, apply every regional exception, or decide whether two people should marry.
Why another calculator may disagree
Astrogyana uses True Chitra, anchored to apparent Spica, and whole-sign houses. This is different from mean Lahiri, even though an older internal alias is named lahiri. Different birth-time handling, sidereal references, tables and exception rules can produce different outputs. Compare these settings before treating a disagreement as an input error.
Free results are available without purchasing a report. Saving is optional; buying a PDF creates a retained private report. A PDF is a reference copy of the calculation. A written human review is a separate optional service when available. Neither option turns a traditional score into a prediction of relationship success.
Compare using your own birth details
The free tool requires both recorded birth times. Read the explanations and choose a paid option only if it is useful to you.
