Time difference between Seattle and Bangkok
Seattle

Bangkok
—
Bangkok is 15 hours ahead of Seattle right now.
Does the gap change?
The gap isn't fixed. Seattle changes its clocks for daylight saving time and Bangkok doesn't, so the difference moves during the year:
- From around March 15, 2027: Bangkok ahead by 14 hours
- From around November 8, 2027: Bangkok ahead by 15 hours
Best time to meet
Normal office hours in Bangkok and Seattle don't overlap. The most workable window is 4 PM to 10 PM in Seattle, which is 7 AM to 1 PM in Bangkok, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
