Is the displayed time accurate?
The clock reads your device system time and updates close to each whole second. If the device clock is wrong, enable automatic date and time synchronization in the operating system first.

Current local time, Beijing time, and world time
Open this page to see the current time immediately. The clock detects your device timezone, updates every second, and can switch to Beijing time, UTC, or another world timezone. Fullscreen mode keeps the large digital clock centered for desks, meeting rooms, and shared displays.
01
How the local current time is detected
On the first visit, the world clock uses the IANA timezone reported by your browser, such as Asia/Shanghai, Europe/London, or America/New_York. It shows the date, weekday, hour, minute, and second without requesting location access. If the browser timezone is wrong, select the correct primary timezone manually.
02
How to check Beijing time
Beijing time is China Standard Time at UTC+8 and uses the IANA identifier Asia/Shanghai. Mainland China keeps the same standard time all year and does not observe daylight saving time. Select Asia · Shanghai as the primary timezone or add it as a city clock to compare Beijing time with your local time.
03
Compare world timezones and city clocks
Current times around the world depend on timezone and daylight-saving rules. This clock uses the browser timezone database and can display up to six additional cities for international meetings, remote work, flights, or live events. UTC offsets update automatically when places such as New York or London enter or leave daylight saving time.
To convert a specific date into Unix time, use the timestamp converter; to count days between dates, use the date calculator.
Current time questions
What is the difference between local time and Beijing time?
Local time depends on the timezone selected on your device. Beijing time is always UTC+8. They are normally the same in mainland China but can differ by several hours elsewhere.
Are my city clocks saved after I close the page?
Yes. The primary timezone, extra cities, and 12/24-hour preference are stored only in the current browser and are not uploaded to a server.
Why does the time difference for some cities change?
Some countries and regions observe daylight saving time, so their difference from Beijing time or UTC can change during the year. The clock follows the browser timezone rules automatically.
