Kathmandu, Nepal keeps Asia/Kathmandu time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Kathmandu's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Kathmandu and shifts a little each day. Kathmandu runs 15 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 Kathmandu.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Kathmandu, updated daily.
The Panchang depends on local sunrise, and Kathmandu's sunrise differs, so its tithi/nakshatra timings are specific to Kathmandu.
