Tanzania runs at +03:00
The zone is Africa/Dar_es_Salaam. Every window on this page is worked out from that offset rather than a rule of thumb, so the times shown are the ones that actually apply to Tanzania.
No daylight saving
Tanzania stays on +03:00 all year. The windows below only move when the caller's own country changes its clocks, not when Tanzania does.
