World Clock is a free online tool for checking current time in major cities around the world. It combines live local time, time zones, UTC offsets, and city time pages so you can compare international locations without opening a separate search for every city.
What this page is for
Use it when you need a fast answer to questions such as “What time is it in London?” or “How many hours ahead is Singapore?” It is useful for remote work, international meetings, travel planning, live events, trading hours, classrooms, studios, and shared office displays.
City coverage
- Current local timezone, detected from the browser.
- 15 priority cities: New York, London, Tokyo, Singapore, Dubai, Los Angeles, Paris, Sydney, Berlin, Seoul, Toronto, Beijing, Taipei, Mexico City, and New Delhi.
- Live time, date relationship, and hour difference for each row.
- A large digital clock for the current timezone, with date, IANA timezone name, and UTC offset.
Popular time zones
Many people compare time by UTC offset rather than city name. Common references include UTC−8 Pacific Time, UTC−5 Eastern Time, UTC±0 GMT, UTC+1 Central European Time, UTC+8 China Standard Time and Singapore Time, UTC+9 Japan and Korea time, and UTC+10 Australian Eastern Time.
Browse by region
The city set is also organized by broad regions: North America, Europe, Asia, Oceania, and the Middle East. This makes the World Clock work as a simple navigation page for city time pages while keeping the main clock interface focused and easy to read.
Accuracy and limits
The clock uses your device time and the browser’s international timezone data. That is usually reliable, but it is not a legal time authority. If your operating system clock or timezone is wrong, this page will reflect that error.
Why this city set is focused
The first set is intentionally limited to major search and scheduling locations instead of becoming a long, hard-to-use list. More cities can be added when the page can provide useful local details, not just another copy of the same clock.
FAQ
Can I switch between 12-hour and 24-hour time?
Yes. Use the format button in the top right.
Can I show or hide seconds?
Yes. Use the seconds button in the top right.
Can I use fullscreen mode?
Yes. The fullscreen button works the same way as on the other clock pages.
Can I open a single city page?
Yes. The city rows link to individual pages under /time/, where each city has its own clock, timezone details, daylight saving notes, and related city links.
Does this replace an official time source?
No. It is a practical browser-based world clock. For legal, aviation, finance, or compliance use cases, verify time against an official time authority.
