Fullscreen Clock
A large, clean clock for a spare screen: digital or clean style, 12 or 24 hours, date and screen-safe drift.
How to use
- Choose 12 or 24 hours, the style and the color.
- Press Full screen or the F key.
- Leave it on a spare monitor, tablet or TV.
Good to know
The controls hide after a few seconds; move the mouse to bring them back.
The clock drifts a few pixels every minute to reduce burn-in on OLED screens, and asks the screen to stay awake in full screen.

Questions
Will my screen go to sleep?
In full screen, supported browsers keep the screen awake. You can also change the display sleep setting on your device.
Does it show my local time?
Yes. It uses your device’s clock and time zone.
