Best time to call Hong Kong from London (and vice versa)

With 8 hours between them there is no hour at which London and Hong Kong are both inside a 9:00–17:00 working day. Teams split across these two cities usually alternate the sacrifice: one week the meeting lands early (7:00–8:00) in London and late (18:00–19:00) in the other city, the next week the other way round. The Timezone Matcher grid shades exactly those compromise hours.
