Why Ahmedabad has its own Panchang
Largest city of Gujarat and birthplace of Mahatma Gandhi. Strong Jain and Vaishnava traditions.
Every timing on this site that matters — Rahu Kaal, Abhijit Muhurat, the moment a tithi turns, the window a puja should begin in — is derived from the Sun's position relative to a specific point on the earth. Ahmedabad sits at 23.02°N, 72.57°E. Serving it Delhi's sunrise would put every muhurat on the page out by minutes, and a muhurat that is out by minutes has stopped being a muhurat. So Trikaal Vaani computes Ahmedabad from Ahmedabad's own coordinates, using Swiss Ephemeris positions rather than tabulated approximations.
Local observance matters as much as local timing. Jagannath Temple Ahmedabad, Hutheesing Jain Temple, ISKCON Ahmedabad shape how festivals are actually kept in Ahmedabad, and the festival pages below carry those regional notes wherever practice diverges from the pan-India form.
