Time difference between Chicago and Bangkok
Bangkok is 12 hours ahead of Chicago
Chicago, the United States is UTC−6 · Bangkok, Thailand is UTC+7 — on standard time
The gap is not the same all year
Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Chicago goes forward on the second Sunday in March and back on the first Sunday in November and Bangkok does not change its clocks.
| Chicago / Bangkok clocks | Difference | How long |
|---|---|---|
| summer / standard | 12 hours ahead | about 34 weeks — most of the year |
| standard / standard | 13 hours ahead | about 18 weeks |
Bangkok stays put all year while Chicago moves, so a meeting fixed in Bangkok's calendar shifts by an hour twice a year at Chicago's end.
When they can both be at their desks
Nine-to-five in Chicago and nine-to-five in Bangkok do not overlap at all. With 12 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
