About World Clock
The World Clock shows the live current time — down to the second — in as many world cities as you like. Add New York, London, Kolkata, Tokyo or any of 40+ major locations and see them all tick side by side.
Each clock card shows the local time, day and date, plus the city's current UTC offset, so daylight saving changes are always reflected. Your selected cities are saved in your browser, so your dashboard is exactly as you left it next visit.
It's the simplest way to keep an eye on colleagues', clients' or family members' local time across the globe.

Frequently Asked Questions
Why does a city's UTC offset change during the year?
Many regions observe daylight saving time, shifting their clocks (and UTC offset) by an hour for part of the year. The world clock always shows the offset currently in effect.
Are my selected cities synced across devices?
No — the list is stored in your browser's local storage for privacy, so each device keeps its own list. Nothing is sent to a server.

Yes, the World Clock is completely free with no usage limits. No signup, no account and no installation required.
Does the World Clock work on mobile?
Yes. The World Clock is fully responsive and works in any modern browser on phones, tablets and desktops.
