Why the Change Is Always on London's Side

Hong Kong has not observed daylight saving time since 1979. The seasonal difference between the two cities is caused entirely by the United Kingdom's DST clock shifts. When London “springs forward” in March, the gap shrinks by one hour. When it “falls back” in October, the gap widens again.

This means the time difference changes without Hong Kong doing anything. If you only remember one thing: London is behind Hong Kong, and the number of hours depends on whether the UK is in GMT or BST.

Best Overlap Hours for Calls and Meetings

Winter (GMT): 16:00-18:00 HKT / 08:00-10:00 GMT
Summer (BST): 15:00-17:00 HKT / 08:00-10:00 BST
