Fullscreen Clock
This fullscreen clock turns your browser into a clean, distracting-free time display you can leave open on any screen. Press fullscreen and you get nothing but the time โ no tabs, no address bar, no notifications. It is the simplest way to give a desk, a second monitor, a classroom projector or a stream a large, glanceable clock.
Why Use a Fullscreen Clock?
A windowed clock competes with everything else on screen. A fullscreen clock removes the competition: the time becomes the only thing you see, so you can read it from across the room without a mental search. For a second monitor that would otherwise sit idle, it is a better use of the space than another empty desktop.

Use It On Any Screen

Second monitor: give an idle screen a job โ a full-screen clock is more useful than a blank desktop. See clock for a second monitor.
