About this tool
World Clock is a free online tool. View the time and date of multiple cities at once.
The page displays the current time for multiple cities, with one panel for each city. Cities can be added or deleted, and search for city names or time zones is supported. Each clock can switch between digital display or analog dial (pointer type). Displays the date, week, and whether it is daylight saving time.
Time calculations are based on the IANA time zone database and use the Intl.DateTimeFormat API to format local time for each time zone. Analog clocks use CSS transform to rotate the hands, or Canvas to draw the dial. Time updates are kept smooth based on requestAnimationFrame.
It is suitable for scenarios where multiple time zones need to be paid attention to: transnational team collaboration, international transactions, contact with relatives and friends overseas, etc. See the time around the world at a glance and avoid making calls or sending messages late at night.
The world clock tool simultaneously displays the current time of multiple cities around the world, and supports custom city lists, analog clocks and digital clocks switching.
