Time difference between Honolulu and Johannesburg

Johannesburg is 12 hours ahead of Honolulu

Honolulu, the United States is UTC−10 · Johannesburg, South Africa is UTC+2 — on standard time

The gap holds all year

Neither city changes its clocks — Honolulu does not change its clocks and Johannesburg does not change its clocks — so 12 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 Honolulu and nine-to-five in Johannesburg do not overlap at all. With 12 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.
