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: Tehran uses the IRR (﷼) and Kingston uses the JMD ($). Language shifts too — Persian (Farsi) in Tehran, English in Kingston. Be careful behind the wheel: Tehran drives on the right, Kingston on the left.

Quick answers. Before you book the call.
What's the time difference between Tehran and Kingston?
Tehran is 8.5 hours behind Kingston. Tehran runs on GMT+3:30 and Kingston on GMT-5. 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.
