How to Use the World Clock

01

View Default Cities

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.

02

Add Custom Cities

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.

03

Compare Time Zones

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.

Time Zone Comparison Tips

Schedule International Meetings

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.

Plan Travel Itineraries

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.

Coordinate Remote Teams

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.

Track Global Events

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.

Frequently Asked Questions

How accurate is the world clock?

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.

How many cities can I add?

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.

Does the world clock work offline?

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.

Why do some cities show the same timezone?

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.

How do I remove a city from my list?

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.
