Know the Time Anywhere
When it's 3 PM where you are, what time is it in Tokyo? London? Sydney? If you work with international colleagues, have family overseas, or follow events in other countries, you need quick access to multiple time zones without calculating offsets in your head.
This world clock displays current time in cities you choose. Add the locations that matter to you, see them all at a glance, and instantly know whether it's a reasonable hour to call or if you should wait until morning their time.
Key Features
Multiple Cities
Add as many locations as you need. Compare New York, London, Tokyo, and Sydney side by side.
Live Updates
Clocks tick in real-time. No refreshing needed — times update every second automatically.
DST Handling
Automatic daylight saving time detection. Times are always accurate regardless of DST transitions.
Date Display
Shows date along with time. Immediately see when it's tomorrow or yesterday in another location.
Common Use Cases
Remote Work Coordination
Distributed teams span multiple time zones. Before scheduling a meeting or sending a message expecting immediate response, check if your colleague is in working hours or sleeping.
International Business
Client calls, partner meetings, and market hours vary by region. A glance at your configured world clock shows which offices are currently active.
Travel Planning
Coordinating flights across time zones, knowing when to call home, or understanding arrival times at your destination — world clock makes these calculations instant.
Following Global Events
Sports matches, live streams, product launches, and news broadcasts happen at local times around the world. Convert those times to your zone to know when to tune in.
Staying Connected with Family
When family members live abroad, knowing their local time helps you reach out during appropriate hours rather than calling at 3 AM their time.
Understanding Time Zones
UTC (Coordinated Universal Time) is the reference point. All time zones are expressed as offsets from UTC. New York is UTC-5 (or UTC-4 during daylight saving), Tokyo is UTC+9, London is UTC+0 (UTC+1 during DST).
Daylight Saving Time complicates things — not all regions observe it, and those that do switch on different dates. The world clock handles this automatically based on each city's current rules.
The Date Line creates situations where it's a different day in different locations. When it's Monday evening in New York, it's already Tuesday morning in Sydney.
Tips for Working Across Time Zones
Find overlapping hours — Look for windows where both parties are in reasonable working hours. Usually there's at least a 2-3 hour overlap even between distant zones.
Rotate meeting times — If recurring meetings always happen at a bad time for one location, take turns with the inconvenient slot so the burden is shared.
Communicate in UTC — When coordinating complex schedules, stating times in UTC eliminates confusion about which local time you meant.
Use calendar invites — Most calendar apps handle time zone conversion automatically. Always include a calendar invite rather than just stating a time in text.
FAQ
How many cities can I track?
Add as many as you need. The interface scrolls if you add more than fit on one screen.
Does it account for daylight saving time?
Yes. Times reflect current DST status for each location. When clocks change, the world clock updates automatically.
Can I save my selected cities?
Your city selections are saved in your browser's local storage. They'll persist when you return to the page.
What if my city isn't listed?
Search for a major city in the same time zone. Within a zone, all cities share the same current time.
Why does it show a different date for some cities?
Time zone differences can cross midnight. When it's 11 PM Monday in New York, it's already 1 PM Tuesday in Sydney.
