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