A giant, calm digital clock for your desk, projector or second monitor. Toggle 12-hour or 24-hour format, show or hide seconds and the date, and see your detected time zone with its current UTC offset below the clock. Press full screen for a clean wall-clock look with nothing else on the page.
About the online clock
A large, distraction-free digital clock that shows your current local time in the browser, with a 12/24-hour toggle, optional seconds and date, and full-screen mode for a desk, projector or second-monitor display.
Sometimes you just want a big, clean clock — on a second monitor, projected in a room, or propped up on a desk — without opening a physical clock app or leaving a browser tab full of distractions. This one shows giant digits, your detected time zone with its current UTC offset, and toggles for 12/24-hour format, seconds, and the date, all saved so it looks the same next time you open it.
When to use it
- A desk or second-monitor clock while working.
- Projecting the time in a classroom, office or shared space.
- A simple, ad-free full-screen clock for a kiosk-style display.
How to use it
- Toggle 12-hour or 24-hour format, and show or hide seconds and the date.
- Press the full-screen button for a clean, distraction-free display.
- Your preferences are remembered for next time.
Tips
- Full screen keeps the screen awake automatically so the clock never dims or sleeps mid-display.
- Hiding seconds gives a calmer, less "ticking" feel for a background display.
FAQ
Is this online clock accurate?
Yes — it reads the time directly from your device's system clock and refreshes every second, so it is exactly as accurate as your computer or phone's clock.
Can I show the clock in 24-hour format?
Yes — use the 12h/24h toggle below the clock to switch between a 12-hour clock with AM/PM and a 24-hour clock.
How do I display this clock full screen?
Press the Full screen button to fill your entire screen with the clock — handy for a desk display, a projector, or a second monitor. Your screen is kept awake automatically while in full screen.
