Can I dim the clock for sleeping at night?

Yes. You can easily toggle between bright daylight mode for office desks and an ultra-low-light nightstand mode. Just click the dimming icon on the screen or press the Down Arrow key to reduce the brightness so it won't hurt your eyes or disrupt your sleep in a dark bedroom.

Will the clock keep working if my Wi-Fi drops overnight?

Absolutely. Once the web page is open, the clock engine runs entirely on your device's local hardware timers. If your home internet goes down or your tablet loses its connection, the full screen clock will continue to display the correct time without interruption.

Distraction-Free Chronometer

A Clean, Distraction-Free Full Screen Display

Transform any spare monitor, old tablet, or smart TV into a stunning, minimalist digital time display. The TimeNumbers Full Screen Clock is designed to completely fill your screen edge-to-edge, hiding all messy browser tabs, bookmarks, and system taskbars. Whether you are setting up a large timer for a classroom exam, a highly visible clock for a corporate conference room, or just want a sleek, distraction-free clock for your study desk, this tool gives you maximum readability from across the room.

We built this clock with long-term display in mind, making it the perfect bedside nightstand companion. If you are running the clock overnight on an OLED smartphone or premium tablet, our built-in pixel-shifting technology gently moves the time display to prevent screen burn-in. You can effortlessly switch to dark mode, lowering the contrast so it provides just enough ambient light to read the time in the middle of the night without illuminating your whole bedroom.

Getting started is incredibly easy with quick keyboard shortcuts. Press 'F' to immediately launch into full-screen mode, hit 'D' to toggle between bright and dark themes, press 'T' to switch between standard 12-hour and 24-hour military time, and tap 'S' to hide or show the running seconds. Best of all, once loaded, it requires no active internet connection, so you can leave it running 24/7 without worrying about data drops or software updates.

Yes. If you leave the clock running overnight on an iPhone, iPad, or OLED monitor, our software gently shifts the numbers by a few microscopic pixels every few minutes. This invisible movement prevents the bright numbers from causing permanent static image retention (burn-in) on your display.
