Tiruchendur, Tamil Nadu, India keeps Asia/Kolkata time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Tiruchendur's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Tiruchendur and shifts a little each day. Even within India, Tiruchendur's sunrise is not identical to Delhi's, so the daily windows shift accordingly. The live panel on each page is recalculated daily for Tiruchendur.
The live panel shows today's day and night Choghadiya for Tiruchendur, recalculated from local sunrise.
Amrit, Shubh, Labh and Char are favourable; Rog, Kaal and Udveg are avoided. Exact times depend on Tiruchendur's sunrise.
