Online Clock

The current time, big and clear.

This online clock reads the time from your device and updates every second. Switch between 24-hour and 12-hour format with a tap. Press F to go fullscreen — handy as a desk clock, a meeting timer reference, or a stream overlay. No signup, works offline once the page has loaded.

Ways to use a fullscreen clock

Put it on a spare monitor as a desk clock that matches your theme. Project it in a meeting room so everyone shares the same idea of "five minutes left". Capture the browser window in OBS or similar software for a clean stream or recording overlay. Or prop up a tablet on a nightstand — in dark mode the display is dim enough not to light up the room.

Quiet on purpose

The clock face stays uncluttered: big digits, your choice of 12-hour or 24-hour format, and nothing else competing for attention. Controls appear only when you move the mouse or touch the screen, then fade away again. Because the time comes straight from your device, it works with no connection at all after the first load.

FAQ

Where does the time come from?

From your device’s system clock. If your computer or phone has the wrong time, this page will too — check your OS clock settings and time zone.

Can I switch between 12-hour and 24-hour format?

Yes. Press the format pill below the clock, or press the H key on your keyboard. Your choice is saved on your device.

Does it work in fullscreen?

Yes. Press F to toggle fullscreen, or use the browser’s fullscreen menu. Press Esc to exit.

Will it work offline?

After the page loads once, the clock keeps running with no internet because the time comes from your device, not a server.
