The MyTempos world clock shows the current local time in cities around the world, updated live every second. Add as many cities as you need and compare them side by side — the clocks stay in sync with your device automatically, no refresh needed.

Each city card shows the local time, UTC offset, and the time offset relative to your location so you know at a glance who is in working hours and who is asleep.

The working hours overlap chart underneath your clocks shows a 24-hour timeline for each city, with business hours highlighted and the current moment marked. This makes it instantly clear when your working day overlaps with a colleague in another timezone — without doing any mental arithmetic.

Your clock list is saved locally in your browser. Close the tab and reopen it — your cities are still there. Nothing is stored on our servers and no account is required.
