When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Hanoi uses the VND (₫) and Fortaleza uses the BRL (R$). Language shifts too — Vietnamese in Hanoi, Portuguese in Fortaleza. Cars drive on the right in both, so rentals feel familiar.

Quick answers. Before you book the call.
What's the time difference between Hanoi and Fortaleza?
Hanoi is 10 hours behind Fortaleza. Hanoi runs on GMT+7 and Fortaleza 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?
Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).
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.
