Vancouver is 15 hours behind Hong Kong
Best overlap: 8:00 AM to 9:00 AM in Hong Kong is 5:00 PM to 6:00 PM in Vancouver.
For a call that suits both sides, look at 8:00 AM to 9:00 AM in Hong Kong / 5:00 PM to 6:00 PM in Vancouver. There's just 1 hour of overlap here, so don't leave meetings to chance — lock 8:00 AM in Hong Kong / 5:00 PM in Vancouver into the calendar. Don't get caught out: Vancouver is the previous day from Hong Kong, so "tomorrow" means different things to each team. Because Vancouver and Hong Kong don't both observe daylight saving, plan to re-check the overlap around March and November.
