Frequently Asked Questions
How do I find the time difference between two cities?
Pick the two cities below. Each page shows the current offset in hours, a worked example (when it is 9:00 AM in one city, what time it is in the other), the overlap of normal working hours, and a note on how daylight saving can shift the gap.
Why does the time difference sometimes change by an hour?
Because regions start and end daylight saving on different dates, and some do not observe it at all. For a few weeks each spring and autumn the usual gap between two cities can be an hour larger or smaller than normal.
What is the best time to schedule an international call?
Aim for the window where both cities are inside normal 9-to-5 working hours. Each city pair page calculates that overlap for you and shows it in the first city local time, so you can pick a slot that is reasonable for everyone.
