Time difference between Buenos Aires and Hong Kong

Hong Kong is 11 hours ahead of Buenos Aires

Buenos Aires, Argentina is UTC−3 · Hong Kong, Hong Kong is UTC+8 — on standard time

The gap holds all year

Neither city changes its clocks — Buenos Aires does not change its clocks and Hong Kong does not change its clocks — so 11 hours is the difference in January and in July alike. That is worth knowing about this pair specifically, because most international pairs do move and a recurring meeting between them does not need checking twice a year.

When they can both be at their desks

Nine-to-five in Buenos Aires and nine-to-five in Hong Kong do not overlap at all. With 11 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
