Dar es Salaam×Vientiane
Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Dar es Salaam uses the TZS (Sh) and Vientiane uses the LAK (₭). Language shifts too — English in Dar es Salaam, Lao in Vientiane. Be careful behind the wheel: Dar es Salaam drives on the left, Vientiane on the right.

Quick answers. Before you book the call.
What's the time difference between Dar es Salaam and Vientiane?
Dar es Salaam is 4 hours ahead of Vientiane. Dar es Salaam runs on GMT+3 and Vientiane on GMT+7. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.
When's the best time to schedule a meeting?
There are 4 hours where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.
Does daylight saving time change the difference?
Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.
