Tiruchirappalli, Tamil Nadu, India keeps Asia/Kolkata time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Tiruchirappalli's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Tiruchirappalli and shifts a little each day. Even within India, Tiruchirappalli's sunrise is not identical to Delhi's, so the daily windows shift accordingly. The live panel on each page is recalculated daily for Tiruchirappalli.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Tiruchirappalli, updated daily.
The Panchang depends on local sunrise, and Tiruchirappalli's sunrise differs, so its tithi/nakshatra timings are specific to Tiruchirappalli.
