The page loads with 20 major cities from around the world, including New York, London, Tokyo, and Sydney. Each city card shows the current time, date, and time difference from your local timezone.
Click the "Add City" button to open the city search modal. Type a city or country name to filter results, then click on a city to add it to your list. Your custom cities are saved automatically.
Hover over any city card to see the time difference from your local timezone. Use this to schedule meetings, plan calls, or coordinate with colleagues and friends across different regions.
Use the world clock to find overlapping working hours between different time zones. For example, 9 AM in New York is 2 PM in London and 10 PM in Tokyo—perfect for US-Europe calls but challenging for Asia-Pacific participants.
Before traveling, check the local time at your destination to prepare for jet lag. Adjust your sleep schedule a few days before departure to minimize the impact of time zone changes.
For distributed teams, identify the "golden hours" when most team members are awake. Use the world clock to rotate meeting times fairly so no single timezone is always inconvenienced.
Watch live events, sports matches, or product launches happening in other time zones. Convert broadcast times to your local timezone to avoid missing important moments.
The world clock uses your device's system time and the Intl.DateTimeFormat API for timezone calculations. This provides accuracy within seconds, which is sufficient for scheduling and coordination purposes.
You can add up to 50 custom cities to your world clock. All cities are stored in your browser's local storage, so they persist across sessions. To add more cities, remove some existing ones first.
Yes, the world clock works offline once the page is loaded. It uses your device's local time and built-in timezone data, so no internet connection is required for time calculations.
Some cities share the same timezone (e.g., Osaka and Tokyo both use Asia/Tokyo). This is correct behavior, as they observe the same local time. The world clock shows all major cities for convenience.
Hover over any city card to reveal the remove button (X icon) in the top-right corner. Click it to remove the city from your list. You can always add it back later using the "Add City" button.
