Intercultural marriages, where one partner is Hindu and the other is not, raise a specific question: does kundli matching even apply, and if so, how?
Everyone has a birth chart
Guna milan only needs a birth date, time and place, it does not require the person to practise Hindu traditions. A chart can be computed for anyone born anywhere, and the astronomical positions of the Moon, planets and nakshatras at that moment are the same regardless of the person’s faith.
What changes is how the family uses the result
Some families run a full Ashtakoota match on both charts, treating it as one input alongside everything else. Others run it only for the Hindu partner as a formality for their own side of the family, without expecting the non-Hindu partner’s family to weigh it the same way. Both approaches are common; there is no single correct rule here, it is a family decision.
What a one-sided reading tells you
If only one partner’s chart is checked (for example, just manglik status), you get information about that person alone, not a compatibility score between the two.
Getting a chart, either way
Use the kundli matching tool for a full comparison, or the kundli tool to generate one person’s chart on its own.
This information is descriptive; it does not make the marriage decision for you.
