A large share of kundli matching requests today involve a bride and groom living on different continents, one in India, one in the US, UK, Canada, Australia, or the Gulf. The distance does not change how the matching works.
What matching actually needs
Guna milan is computed from each person’s birth date, time and place, nothing else. The Ashtakoota system compares two charts mathematically; it does not require both people to submit their details from the same location or at the same time.
Getting birth details right across time zones
The one place distance actually matters is making sure the birth time is recorded in the correct local time zone of the birth city, not the time zone either family currently lives in. A birth in Houston at 9 PM CST is not the same instant as 9 PM IST, and using the wrong zone shifts the chart.
Coordinating the report
Once both sets of birth details are ready, the kundli matching tool generates one shared report that either family can review independently, from wherever they are. For more on using these tools from abroad, see the guide for Indians abroad.
This information is descriptive; it does not make the marriage decision for you.
