Online Clock

How to use the online clock

The clock shows the current time from this device, along with the weekday and the date. The Digital and Analog buttons switch between a large number display and a classic clock face with hour, minute and second hands. The 12h and 24h buttons change the digital format, and the Seconds checkbox shows or hides the seconds in both styles. These settings stay saved in this browser for the next visit.

Full screen mode

Full screen fills the whole display with the clock, which suits a spare monitor, a tablet on a desk or a screen in a meeting room or classroom. A double click on the clock does the same. Press Esc or the button again to leave full screen. While the clock is in full screen, the page asks the browser to keep the screen awake, on browsers supporting the Screen Wake Lock API.

Accuracy

The clock reads the system time of the device, so the accuracy matches the device clock. Phones and computers synchronise with internet time servers and usually stay within a fraction of a second. The second hand on the analog face moves smoothly, and the display follows the light or dark theme of the site.
