Irving, Texas, United States keeps America/Chicago time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Irving's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Irving and shifts a little each day. Irving runs 10 hours 30 minutes behind India, so a timing copied from an Indian panchang is wrong here. The live panel on each page is recalculated daily for Irving.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Irving, updated daily.
The Panchang depends on local sunrise, and Irving's sunrise differs, so its tithi/nakshatra timings are specific to Irving.
