Bangkok, Thailand keeps Asia/Bangkok time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Bangkok's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Bangkok and shifts a little each day. Bangkok runs 1 hour 30 minutes ahead of India, so a timing copied from an Indian panchang is wrong here. The live panel on each page is recalculated daily for Bangkok.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Bangkok, updated daily.
The Panchang depends on local sunrise, and Bangkok's sunrise differs, so its tithi/nakshatra timings are specific to Bangkok.
