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