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.
