Understanding the Bangkok – London Time Difference
Bangkok runs on Asia/Bangkok, currently UTC+7:00. London runs on Europe/London, currently BST (UTC+1:00). The gap of 6 hours is simply the distance between those two offsets.
London observes Daylight Saving Time and Bangkok does not, so the gap between them shifts by an hour twice a year. The next shift is on Sunday, October 25, 2026, when London adjusts its clocks and the difference becomes 7 hours. Anything scheduled across that date needs checking again.
