How We Verify Panchangam Information

Every publisher entry in our Panchangam Library is cross-referenced against the publisher's official website (where available), Wikipedia citations, and primary sources. Calculation system designations (Drik / Vakya / Surya Siddhanta) follow the publisher's stated methodology — these are not interchangeable and produce different tithi-junction times for the same date.
