Make it your clock
Choose 12- or 24-hour time, show or hide seconds and the date, and switch between light and dark themes. Select Fullscreen for a larger clock. Use Tab to move between controls, then Enter or Space to change a setting.
A note on accuracy
The clock follows your device’s local time and time zone. If your device time is incorrect, the clock will be too. It does not connect to an external time service.
Good to know
Where does the time come from?
Your device’s system clock supplies the time and date. The display updates from that clock and refreshes when you return to this page.
How do I use the fullscreen clock?
Select Fullscreen, then press Esc or tap Exit fullscreen to leave. If your browser does not support fullscreen, you can still use the large clock on this page.
Can I change the format or hide seconds?
Use the format button for 12- or 24-hour time. Seconds and Date each have their own switch.
Will my settings be saved?
Display preferences are saved in this browser when local storage is available. Clearing site data or changing browsers resets them.
Will it keep my screen awake?
No. Adjust your device’s sleep settings if needed. Closing this page stops the display; reopening it shows the current time.
