Frequently asked questions

What is the best time to schedule a meeting across time zones?

Aim for the overlap in both cities' working hours (9am–6pm). When the zones are far apart, early morning for the western city often lines up with late afternoon for the eastern one.

How do I find overlapping business hours between two cities?

Open the city-to-city converter for the two places — it shows a 24-hour table and highlights the hours when both are within normal working hours.

Does the planner handle daylight saving time?

Yes. All times are DST-aware and update automatically when either city changes its clocks, so the overlap stays correct year-round.

Can I plan a meeting across more than two time zones?

Yes — the converter supports multi-city chains (for example London, New York and Tokyo), so you can compare several places at once.
