◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Antananarivo uses the MGA (Ar) and Porto Alegre uses the BRL (R$). Language shifts too — French in Antananarivo, Portuguese in Porto Alegre. Cars drive on the right in both, so rentals feel familiar.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Antananarivo and Porto Alegre?

Antananarivo is 6 hours behind Porto Alegre. Antananarivo runs on GMT+3 and Porto Alegre on GMT-3. 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 2 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.
