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