Bangkok & London — Business & Scheduling Guide
Bangkok (Thailand) is an important regional economy, with key industries in diverse sectors including services and trade. London (United Kingdom) is a leading center for finance and international trade, known for finance, insurance, media, and professional services. With a 7-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.
Scheduling Meetings Between Bangkok and London
The 7-hour difference between Bangkok and London requires careful scheduling. The best overlap window is typically 2–4 hours when both cities are within working hours. Business hours typically follow a 9 AM–5 PM schedule. British business culture values politeness and punctuality, with typical hours of 9 AM–5:30 PM. Teams often designate specific "overlap hours" for real-time collaboration and use asynchronous communication (Slack, email, recorded video) for the rest of the day.
Daylight Saving Time Considerations
London observes Daylight Saving Time (GMT/BST), while Bangkok stays on ICT year-round. When London switches to daylight time, the effective time difference shifts by 1 hour. This typically happens in spring and fall, and the exact dates vary by country. If you have recurring cross-timezone meetings, recalculate the schedule after each DST transition.
