Fullscreen Clock
A fullscreen clock fills your screen with the current time in large, readable digits. This page opens a clean digital clock built for shared displays — classrooms, offices, studios, and reception screens — where the time needs to be visible from across the room without the clutter of a normal desktop. Open it, pick your options, and switch to full screen for a distraction-free display.
Built to be read from a distance
The whole point of a fullscreen clock is legibility. Instead of a tiny system clock in the corner of a screen, the time is shown in tall numerals that stay clear from the back of a room. In full screen the browser chrome disappears, so there are no tabs, bookmarks, or notifications competing for attention — just the time.
That makes it useful anywhere a group needs to share the same reference: a classroom pacing an activity, a meeting room keeping to a schedule, a studio wall during a live session, or a desk where you simply want a large, calm clock in view while you work.
Options that adapt to the room
Choose 12-hour or 24-hour format to match your setting, and turn the seconds column on when precise timing matters or off for a calmer display. Pick a dark theme for dim rooms and evening sessions, or a light theme for bright daylight. The font size scales up so the digits can fill even a large projector.
For screens that stay on for hours, burn-in protection gently shifts the display so a static image does not mark the panel, and the fullscreen mode requests a screen wake lock on supported browsers so the clock does not dim or sleep.
Opening and keeping it handy
Press the button to launch the clock, then use full screen for the cleanest large-screen view. You can share it on a classroom display, meeting-room monitor, tablet, projector, or second screen. If you use it often, add it to your home screen or bookmark it so it is one tap away.
The clock reads the time from the device it runs on, so it stays accurate as long as that device's clock is correct — which modern laptops, phones, and tablets keep in sync automatically over the network.
Frequently asked questions
How do I make the clock fullscreen?
Open the clock and use the fullscreen button, or your browser's fullscreen option. The browser chrome disappears and the time fills the screen with large numbers.
Can I switch between 12-hour and 24-hour time?
Yes. The settings let you choose 12-hour format with AM and PM or 24-hour format, and turn the seconds column on or off.
Will the screen stay awake while the clock is showing?
In full screen the page requests a screen wake lock on supported browsers, so the display does not dim or sleep. On devices without support, disable sleep in the system settings for long sessions.
Does it work on a phone or tablet?
Yes. It runs in any modern browser, so it works on phones, tablets, laptops, and shared displays. You can also add it to your home screen for quick access.
Is the fullscreen clock free?
Yes. It runs in the browser with no account or install.
