Turn any screen into a clock
This full screen clock shows the time in large, clear figures on any computer, tablet, phone or TV with a browser. Choose one of four styles, add the seconds or the date, pick a color and go full screen. There is no app to install and no account. The page asks the screen to stay on while it is open, so your clock does not vanish after a few minutes. The time comes from your device, so the clock is as accurate as the device itself.
Use it as a desk clock, a kitchen clock, a wall clock on a spare tablet, a clock on the living room TV, a display in a classroom or a soft bedside clock at night.
Four clock styles
Digital
Big, bold digits readable from across the room. It is the simplest and clearest style, perfect for classrooms and offices.
Flip
A retro flip clock: the numbers sit on split panels that flip over as the time changes, like the clocks on nightstands in the 1970s.
Words
The time written out the way you would say it, such as “It’s twenty past seven” or “It’s quarter to four”, with the seconds on a separate line. It is calm and friendly, and great for children learning to tell time.
Watch
A photo of a luxury skeleton watch with its movement on display. The hands turn in real time, and the seconds hand sweeps smoothly around the dial instead of ticking.
Each style works with every color, size and full screen option, so you can mix and match until the clock suits the room.
Set it up your way
- Seconds: show them, or hide them for a calmer display.
- Date: show it in one of three formats and tap the date to switch: Monday, June 1; Mon, Jun 1, 2026; or 06/01/2026.
- Size: use the minus and plus buttons to make the clock bigger or smaller.
- Color: tap the round button at the bottom right. Choose any hue, make it lighter or darker, enter a hex color code, try a random color or let the colors change slowly. A black and white (B/W) option gives a classic look.
- Quotes: in full screen, about fifty quotes about time can appear on screen. Hide them if you prefer a clean display.
- 12-hour time: the English version shows the time with AM and PM.
Your choices are saved in your browser, so the clock looks the same the next time you open it on that device.
Where to use a full screen clock
On a desk or a spare tablet
An old tablet propped on a shelf makes a handsome desk or wall clock. The Flip and Watch styles look great in a home office, a shop or a waiting room.
On a TV
Open the page in the TV browser, or share your computer screen, then go full screen. The Digital style reads easily from the couch, and the date helps on busy mornings. A TV in an office break room works just as well.
In the classroom
Project the clock so students always know how long until the bell. The Words style helps younger students practice reading the time, and switching between the Watch and Words styles connects the position of the hands with the words for the time. For a countdown during a test, switch to the online timer or the 45 minute timer.
In the kitchen
A tablet on the counter shows the time in big digits while you cook, readable even with flour on your hands. For countdowns, keep the online timer open in another tab.
At events
Show the time on a big screen at a conference, a rehearsal, a reception desk or backstage, so speakers and staff stay on schedule.
By the bed at night
Pick a very dark color with the Darker option and hide the seconds for a soft, low-glow bedside clock. Need to wake up at a set time? The online alarm clock has a night mode that turns the screen almost black.
Tips for a clock that stays on
- Plug the device in: a screen that runs all day uses a lot of battery.
- The page asks the browser to keep the screen on while it is open. Some devices still apply their own power settings, so check the screen timeout if it goes dark.
- On a computer, press Esc to leave full screen. The bar with size and exit appears when you move the mouse or touch the screen.
- For a room-sized display, pick the Digital style, hide the date and push the size up.
- On a TV, check the TV’s own screen saver settings, which may dim the picture after a while.
- For a lounge or a shop window, try the slowly changing colors for a living, ambient display.
- Bookmark the page: your style and color will be waiting for you next time.
A few words about clocks
Flip clocks go back further than you might think. The Plato clock, patented by Eugene Fitch in 1903 and shown at the 1904 World’s Fair in St. Louis, was one of the first. The style became an icon in the 1960s and 1970s: the Cifra 3, designed by Gino Valle for the Italian company Solari in 1965, is in the collection of the Museum of Modern Art in New York.
Skeleton watches reveal the gears and springs of a mechanical movement through an open-worked dial. Many mechanical watches beat several times per second, so their seconds hand seems to glide rather than jump. That smooth sweep is what you see in the Watch style.
Why twelve hours? The ancient Egyptians divided the day and the night into twelve hours each, a habit that survives in the two turns of the hour hand around a clock face. In the United States, the 12-hour clock with AM and PM is the norm. AM stands for ante meridiem, before noon, and PM for post meridiem, after noon. The 24-hour clock, often called military time, is standard in much of the world, and it is what the French version of this site shows.
Private, free and accessible
There is no account, and nothing is sent to a server: the style, color, size and date format stay in your own browser. Once the page has loaded, the clock keeps running offline. Large digits, a black and white option and a time-in-words style make it easy to read for everyone. For timing tasks, see the stopwatch and the Pomodoro timer.
