Time difference between Perth and Buenos Aires
Buenos Aires is 11 hours behind Perth
Perth, Australia is UTC+8 · Buenos Aires, Argentina is UTC−3 — on standard time
The gap holds all year
Neither city changes its clocks — Perth does not change its clocks and Buenos Aires 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 Perth and nine-to-five in Buenos Aires 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.
