About the Full-Screen Clock

Sometimes you just want a big, clear clock — on a second monitor, a tablet propped on your desk, a TV during an event, or a laptop at the front of a room. This full-screen clock turns any screen into exactly that, with styles ranging from clean minimal digits to a retro flip clock and a glowing neon look.

Choose 12 or 24-hour time, decide whether to show seconds and the date, pick a skin and go full screen. It reads your device's local time so it's always accurate, and because it runs in your browser it's instant, private and free.
