Luton, England, United Kingdom keeps Europe/London time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Luton's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Luton and shifts a little each day. Luton runs 4 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 Luton.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Luton, updated daily.
The Panchang depends on local sunrise, and Luton's sunrise differs, so its tithi/nakshatra timings are specific to Luton.
