Why people convert Bangkok to UTC time
- Scheduling a call from Bangkok to UTC: a 10:00 AM start in Bangkok lands at 3:00 AM in UTC, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Bangkok and UTC are inside the 9-to-5 working day between 4:00 PM and 5:00 PM ICT time (9:00 AM–10:00 AM UTC). That is roughly 1 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Bangkok is 1:00 PM in UTC makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -7h gap is not.
- Block 4:00 PM–5:00 PM ICT as the recurring meeting window if you work primarily from Bangkok and need UTC colleagues present.

About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.

Business hours overlap
Bangkok and UTC overlap for only 60 minutes (4:00 PM–5:00 PM ICT), so meetings have to be booked precisely.
Bangkok is 7 hours behind UTC (ICT UTC+07:00 → UTC UTC+00:00). The shared working window is 4:00 PM–5:00 PM ICT. Remember to re-check around daylight-saving transitions.
