Hanoi×Chiang Mai
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 Chiang Mai uses the THB (฿). Language shifts too — Vietnamese in Hanoi, Thai in Chiang Mai. Be careful behind the wheel: Hanoi drives on the right, Chiang Mai on the left.

Quick answers. Before you book the call.
What's the time difference between Hanoi and Chiang Mai?
Hanoi and Chiang Mai share the same offset (GMT+7), so there's no difference right now.
When's the best time to schedule a meeting?
There are 8 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.
How far is Hanoi from Chiang Mai?
About 760 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 1h 24m, not counting airport time, winds, or routing around restricted airspace.
Can I send this meeting time as a calendar invite?

What currency do Hanoi and Chiang Mai use?
Hanoi uses the Vietnamese đồng (VND, ₫); Chiang Mai uses the Thai baht (THB, ฿). Check the live rate before transferring money or paying with a card abroad — most banks add a 1–3 % FX margin on top of the mid-market rate.

Dial the international prefix used by your carrier (often 00), then +84, then the local number — drop any leading zero of the city or mobile code. For free calls, WhatsApp, Signal, and FaceTime work over Wi-Fi regardless of country code.
What language is spoken in Hanoi and Chiang Mai?
Hanoi primarily speaks Vietnamese; Chiang Mai speaks Thai. English is widely used in business contexts in major cities of both, but written contracts may need translation.

No. Vietnam drives on the right, Thailand on the left. If you're renting, expect a learning curve on the first day — especially at roundabouts and when judging the centre of the lane.
