Time difference between Jakarta and Perth

Perth is 1 hour ahead of Jakarta

Jakarta, Indonesia is UTC+7 · Perth, Australia is UTC+8 — on standard time

The gap holds all year

Neither city changes its clocks — Jakarta does not change its clocks and Perth does not change its clocks — so 1 hour 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.
