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: Adelaide uses the AUD ($) and Sofia uses the BGN (лв). Language shifts too — English in Adelaide, Bulgarian in Sofia. Be careful behind the wheel: Adelaide drives on the left, Sofia on the right.

What's the time difference between Adelaide and Sofia?
Adelaide is 6.5 hours behind Sofia. Adelaide runs on GMT+9:30 and Sofia 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 1 hour 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.
