Hong Kong is 15 hours ahead of Los Angeles

Los Angeles, the United States is UTC−8 · Hong Kong, Hong Kong is UTC+8 — 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 Los Angeles goes forward on the second Sunday in March and back on the first Sunday in November and Hong Kong does not change its clocks.

When they can both be at their desks

Nine-to-five in Los Angeles and nine-to-five in Hong Kong do not overlap at all. With 15 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.
