Time difference between San Diego and Hong Kong
San Diego

Hong Kong
—
Hong Kong is 16 hours ahead of San Diego right now.
Does the gap change?
The gap isn't fixed. San Diego changes its clocks for daylight saving time and Hong Kong doesn't, so the difference moves during the year:
- From around March 15, 2027: Hong Kong ahead by 15 hours
- From around November 8, 2027: Hong Kong ahead by 16 hours
Best time to meet
Normal office hours in Hong Kong and San Diego don't overlap. The most workable window is 3 PM to 10 PM in San Diego, which is 7 AM to 2 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.
