Time difference between Seattle and Hong Kong
Seattle

Hong Kong

Hong Kong 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 Hong Kong doesn't, so the difference moves during the year:
- From around November 2, 2026: Hong Kong ahead by 16 hours
- From around March 15, 2027: Hong Kong ahead by 15 hours
Best time to meet
Normal office hours in Hong Kong 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 Hong Kong, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
