Why Chennai Needs a Local Panchang
Panchang timing depends on the observer location. Even within the same timezone, sunrise and local longitude can shift practical windows for puja, vrata, travel, signing, and festival routines. Chennai uses the Asia/Kolkata timezone, but its local latitude and longitude still matter.
What This Pilot Tracks
- City coordinate baseline: 13.0827, 80.2707
- Timezone baseline: Asia/Kolkata
- Tamil panchangam context for temple, household, and festival planning.
- Chennai validation should include Tamil calendar terminology and local sunrise boundaries.
