What is a world clock for?

It’s the quickest way to check whether it’s a good time to call someone abroad, confirm the local time for a connecting flight, or follow a live event in another country. Each card shows the time, day of the week, and difference from the first clock in your list—handy when it’s already “tomorrow” on the other side of the world.

• Automatic daylight saving time: Each location’s rules come from the IANA time zone database built into your browser, the same one used by phones and computers.
• Your time zone: “This device’s time” uses the time zone set on your phone or computer.
• No sign-up: Your list is saved in your browser and included in your My Rotina backup.

Time differences change throughout the year

Some places observe daylight saving time and others don’t, so the time difference between two cities can change during the year. The world clock shows the difference for today. To check when the clocks change, use the time zone difference tool.

To find out what time it will be somewhere else at a specific time—such as for a meeting, game, or livestream—use the time zone converter. You can also check the local time in cities around the world on our what time is it page.
