World Clock
Compare current civil times, dates, and UTC offsets across multiple cities and IANA timezones in one view.
Run tool
World Clock lets you check the current civil time across international timezones from one clean dashboard. Enter standard IANA timezone identifiers such as America/New_York or Asia/Tokyo, or type familiar city aliases like London, Paris, or Sydney separated by commas. Leaving the input blank automatically loads a curated default list of major cities spanning multiple global regions. Each recognized location displays its current local clock time in both 12-hour and 24-hour formats, calendar date, active UTC offset, timezone abbreviation, and full ISO timestamp. Times synchronize to the current UTC second so you can coordinate international meetings, schedule software deployments, or track remote colleagues accurately. You can compare up to thirty distinct locations in a single view. The tool skips unrecognized names and lists them separately, ensuring that valid entries continue to display their local times clearly without disruption.
Instructions
- Enter one or more comma-separated timezone names or city aliases in the input box, or leave the field blank to display default world cities.
- Run the tool to calculate current civil times relative to the current UTC timestamp.
- Review the generated cards for each location to view 12-hour and 24-hour times, calendar dates, UTC offsets, and timezone abbreviations.
Examples
- America/New_York, Europe/London, Asia/Tokyo - Displays current local time, calendar date, UTC offset, and abbreviation for New York, London, and Tokyo simultaneously.
- Empty input - Generates a default world clock view spanning major regional hub cities across several continents.
FAQ
Can I enter city names instead of formal IANA identifiers?
Yes. The tool recognizes common city names like London, Paris, or Tokyo as aliases, in addition to standard IANA timezone identifiers like America/Los_Angeles.
What happens if I leave the timezone field blank?
If you leave the input blank, the tool automatically displays a default set of major cities across different global regions.
How many timezones can I compare at once?
You can enter up to 30 nonblank timezone entries in a single request. Requests with more than 30 entries will prompt you to shorten the list.
What happens if I enter an invalid or mistyped timezone?
Any unrecognized names are excluded from the main clock list and reported separately. If none of your entries are valid, the tool prompts you to check your input.
