World Clock
Current local time in 20 major cities updating every second
About this tool
This free world clock shows the current local time in 20 major cities around the globe, updating every second. Each city card displays the date, day of week, and a subtle background tone indicating whether it is night, early morning, business hours, or evening in that location — giving you an instant sense of who is awake and when.
Cities covered include New York, Los Angeles, Chicago, Toronto, London, Paris, Berlin, Dubai, Mumbai, Singapore, Tokyo, Seoul, Sydney, and more. This covers the most important global business hubs and time zones, from UTC−12 to UTC+14. For more precise time zone conversions between any two specific cities, use the companion Time Zone Converter tool.
Remote and distributed teams rely on world clocks to avoid the friction of mentally converting times before every meeting or message. Knowing that it's 11 PM in Singapore when you send a "quick question" Slack message sets appropriate expectations for response time. For global product launches, knowing the exact local time in each target market helps coordinate announcements for maximum impact.
Frequent travelers also benefit from glancing at a world clock before calling family back home — jet lag can make it easy to lose track of time differences. The clock updates in real time using your device's system clock and the IANA Time Zone Database, with no API calls or server requests.
