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: Detroit uses the USD ($) and Colombo uses the LKR (Rs රු). Language shifts too — English in Detroit, Sinhala in Colombo. Be careful behind the wheel: Detroit drives on the right, Colombo on the left.

Quick answers. Before you book the call.
What's the time difference between Detroit and Colombo?
Detroit is 9.5 hours ahead of Colombo. Detroit runs on GMT-4 and Colombo on GMT+5:30. 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.
How far is Detroit from Colombo?
About 14,270 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 17h 17m, not counting airport time, winds, or routing around restricted airspace.

What currency do Detroit and Colombo use?
