A fullscreen digital clock turns any spare screen into a clear time display. To use it, open the digital clock, choose 12 or 24-hour time, decide whether to show seconds and the date, then tap fullscreen. The digits scale to fill the display, so an old monitor or tablet becomes a desk clock you can read from across the room.
It runs in your browser, free, with no sign-up, and keeps working offline once loaded.
Set it up the way you want
- Pick 12-hour for a clock with AM and PM, or 24-hour for a single 0 to 23 reading.
- Turn Seconds on if you want the live tick, or off for a calmer face.
- Turn Date on to show the weekday and full date under the time.
- Tap fullscreen to fill the screen and hide everything else.
Your choices are saved on your device, so the clock opens the way you left it next time. Nothing is sent anywhere to do that.
Good places to use it
- A spare screen as a desk clock. Stand an old tablet or monitor on your desk and leave the clock running fullscreen.
- Studios and workspaces. A large, glanceable time that does not crowd the screen with anything else.
- Calls and streams. A clean time display you can keep in view or share.
- A bedside or kitchen clock. Repurpose a device you no longer carry around into a simple clock.
Why it stays accurate
The clock reads the time your device already keeps, which is itself synced by your operating system. That means it matches your phone and computer without you setting anything, and it does not drift the way a battery wall clock can. There is no server involved, so the time appears the instant the page loads.
For the best desk-clock setup, install the page to your home screen. It then opens in its own window like an app and keeps the time on a dedicated screen.
When you need more than one time zone
If you want to see the time in several cities at once rather than one local clock, the world clock shows them side by side with daylight saving handled. To wake or be reminded at a set time, the alarm clock adds a tone and a snooze.
