Type in the "Add a city" box and choose a result, or press Enter to add the first one. You can search by city, country or time zone name, and there are more than 170 major cities to choose from. Press the × on a row to remove it. The list holds up to 12 cities.

Does it handle daylight saving time?

Yes. Each row uses the time zone database built into your browser, so every city switches to or from daylight saving on its own dates. That also applies when you drag the slider to another time, since the offset is worked out for that moment.

How does the compare times slider work?

Drag "Compare times" to choose a time of day in your own zone, in 15-minute steps. Every city then shows what its clock and date will read at that moment. Press "Now" to go back to live time.

How are day and night decided?

A city counts as daytime from 06:00 up to 18:00 on its own clock, and as night otherwise. This is a simple rule, not a sunrise and sunset calculation, so use it as a quick hint when picking a meeting hour.

Is my list saved, and which time is "Your time"?

Your city list is saved in this browser's local storage, not in the page address, and nothing is uploaded. "Your time" comes from your device clock and time zone, so the other rows are only as accurate as that clock.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install.

How It Works

The page asks your browser's built-in time zone data (Intl) for the time in each city, once a second, and shows the gap to your own zone.

Type in "Add a city" and pick a result. Your own time is always shown at the top.

Read each row
Each row shows the city time and date, how far it is from you, and a sun or moon for day or night.
