Each comparison lays the two cities' clocks side by side for all 24 hours and shades the stretch where both are at work, so the best time to call is obvious at a glance. It's the same engine behind the base finder — where you can turn any pairing into a livability score for working remotely across it.

FAQ

Does the difference account for daylight saving?

Yes. Offsets come live from each city's IANA time zone, so the difference is right even in the weeks around spring and autumn clock changes when countries switch on different dates.

How do I find the best meeting time?

Each pair page highlights the hours when both cities are inside a 9-to-5 working day and names the overlap window in UTC.
