Cupertino, California, United States keeps America/Los_Angeles time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Cupertino's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Cupertino and shifts a little each day. Cupertino runs 12 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 Cupertino.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Cupertino, updated daily.
The Panchang depends on local sunrise, and Cupertino's sunrise differs, so its tithi/nakshatra timings are specific to Cupertino.
