Track Time Across the Globe

This free world clock displays live times for 12 major cities spanning every inhabited continent. Each clock card shows the current time, date, and UTC offset. All times are computed using the JavaScript Intl.DateTimeFormat API, which leverages the IANA timezone database built into your browser. That means daylight saving changes are handled automatically with no manual adjustment needed.

Adding Custom Timezones

If the city you need is not in the default list, use the dropdown to select from over 400 IANA timezones. Click Add and a new clock card will appear instantly. This is especially useful for remote teams spanning unusual timezone combinations. For scheduling meetings across zones, our timezone converter lets you compare specific times side by side.

Accuracy and Privacy

The world clock runs entirely on your device. No server calls are made after the page loads, so it works offline and your data stays private. The accuracy depends on your system clock — if your computer time is correct, the displayed times will be correct. For Unix-style timestamps, check out our Unix timestamp converter.

Understanding UTC Offsets

Each clock card displays the UTC offset for that timezone. UTC (Coordinated Universal Time) is the global time standard. Offsets range from UTC-12 to UTC+14. During daylight saving time, offsets shift by one hour for participating regions. The world clock automatically reflects these changes based on the current date.

Frequently Asked Questions

How does the world clock determine the time?
The tool uses the JavaScript Intl.DateTimeFormat API with IANA timezone identifiers. This means the times are derived from your operating system's timezone database and are automatically adjusted for daylight saving time.
Can I add a city not in the default list?
Yes. Use the "Add Timezone" dropdown to select any IANA timezone. Over 400 timezones are available, covering every region in the world.
Does the world clock account for DST?
Yes. Because the tool uses IANA timezone identifiers, daylight saving transitions are handled automatically by your browser's built-in timezone data.
Is the world clock accurate offline?
Yes. Once the page is loaded, it runs entirely on your device's clock with no server requests. The times are as accurate as your system clock.
