Best Meeting Time: Hong Kong & London

Hong Kong is currently 8 hours ahead of London (this can shift with daylight saving time). Working hours (9am–6pm) overlap from 5 PM to 6 PM Hong Kong time. ClockAlign ranks the slots inside that window by when both sides are cognitively sharp, not just awake.
