When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Hong Kong uses the HKD ($) and Köln uses the EUR (€). Language shifts too — English in Hong Kong, German in Köln. Be careful behind the wheel: Hong Kong drives on the left, Köln on the right.

Quick answers. Before you book the call.
What's the time difference between Hong Kong and Köln?
Hong Kong is 6 hours behind Köln. Hong Kong runs on GMT+8 and Köln on GMT+2. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.
When's the best time to schedule a meeting?
There are 2 hours where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.
Does daylight saving time change the difference?
Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.
