London and Bangkok: time difference and best meeting times

Bangkok is 6 hours ahead of London for most of 2026. With a 9:00 to 17:00 working day in both places, you share between 1 hour and 2 hours each day, so the overlap needs protecting.

Shared working hours

The table assumes a working day of 9:00 to 17:00 in both cities. Times are local to each city. January and July show the two ends of the year, because daylight saving changes the picture.

SeasonTime differenceShared hoursShared window in LondonShared window in Bangkok
January (15 January) 7 hours 1 hour 09:00 to 10:00 16:00 to 17:00
July (15 July) 6 hours 2 hours 09:00 to 11:00 15:00 to 17:00

Treat the shared window as scarce. Schedule the meetings that need both sides inside it, and keep each one short so there is room for more than one. A good default slot is 09:30 to 10:30 in London, which is 15:30 to 16:30 in Bangkok. Everything that does not need a live conversation, such as status updates and reviews, works better as written messages that the other side reads at the start of their day.

With a longer day, 08:00 to 18:00

If people on both sides can start an hour earlier and finish an hour later, the shared time becomes 3 hours in January and 4 hours in July. In January that is 08:00 to 11:00 in London, which is 15:00 to 18:00 in Bangkok. In July it is 08:00 to 12:00 in London, which is 14:00 to 18:00 in Bangkok.

The gap between London and Bangkok is not constant. United Kingdom and Thailand do not move their clocks on the same dates, so the difference changes 2 times in 2026. A meeting that sits comfortably in the shared window for part of the year can land outside it for a few weeks. Check the table above whenever you set a recurring meeting that spans a change.

Tips for teams in London and Bangkok

  • Name both cities in the invitation, for example "09:30 to 10:30 London / 15:30 to 16:30 Bangkok".
  • Check recurring meetings when clocks change. The gap is 7 hours instead of 6 hours for part of the year, so the shared window moves.
  • Keep the shared 1 hour for meetings, and do focused work outside it.
