Sofia×Chiang Mai
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: Sofia uses the BGN (лв) and Chiang Mai uses the THB (฿). Language shifts too — Bulgarian in Sofia, Thai in Chiang Mai. Be careful behind the wheel: Sofia drives on the right, Chiang Mai on the left.

Quick answers. Before you book the call.
What's the time difference between Sofia and Chiang Mai?
Sofia is 4 hours ahead of Chiang Mai. Sofia runs on GMT+3 and Chiang Mai 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.
How far is Sofia from Chiang Mai?
About 7,450 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 9h 16m, not counting airport time, winds, or routing around restricted airspace.
