A full screen countdown timer for any screen
Put a timer on screen in one click — 5, 10, 15, 30 or 60 minutes — or set a date and count down to it. Either way it fills a projector, a TV, or a second monitor, free and with nothing to install, and the fullscreen control fades out so only the numbers are left.
Try it on the timer here. Pick a preset for a minutes timer, or open the builder to count down to a date of your own.
Put a timer on screen
Pick a length — the timer starts on the clock below and fills the screen in the same click. No signup, nothing to install.
Full Screen Countdown
The example counts to January 1 — pick a preset above for a minutes timer, or set your own date in the builder. The fullscreen button sits in the clock's bottom-right corner.

Three steps, no account, and about twenty seconds — and for a plain minutes timer, the presets above skip all three.
Set your date and time
Pick the exact moment you're counting to — the clock ticks down to the second.
Pick colors that read from the back of the room
High contrast wins on a big screen. Your background color fills the entire display in fullscreen.
Click the fullscreen button on the clock
The control sits in the bottom-right corner of the countdown. One click and the timer takes over the screen.

Styles chosen for legibility at a distance, not for a phone in your hand. Pick one and jump straight into customization.
Stage Black
Maximum contrast for projectors, stage screens, and bright rooms.
Midnight Blue
Easy on the eyes when the clock stays up on a second monitor all day.
Classroom White
Dark digits on white — the combination that survives a washed-out projector.
Neon Night
High-glow green for streams, parties, and dark rooms.
Lobby Warm
Softer tones for a reception screen or shop window counting to opening day.
A custom countdown timer, sized for the room
Fullscreen is only half of it — what fills the screen is yours to design. Pick any background and text color from a full color picker, choose one of five fonts, set the alignment, and decide whether the title and target date appear at all. The preview updates as you customize, so you can judge the contrast before it ever reaches a projector.
That matters more at size than it does in a browser tab: a color pairing that looks fine on a laptop can wash out completely on a projector in a bright room. Build the custom countdown first, then take it fullscreen and check it from the back of the room.
A big online timer everyone in the room can read
In fullscreen the digits step up to the largest size the clock has, the title grows with them, and your background color runs edge to edge — no browser chrome, no site header, no white margin around a dark design. That is the difference between a countdown on a laptop and one that works on a wall.

- A five- or ten-minute timer on screen for a break, a drill, or a quiz round
- Conference stage and breakout screens counting down to doors open
- A second monitor at your desk, kept on screen all day

- Lobby, shop-window, and trade-show displays counting to a launch
- A TV at a party — New Year's Eve being the obvious one
Every countdown here goes full screen
Fullscreen is not a separate mode you have to set up — it is the same button on every countdown across the site. Start from whichever page matches your occasion and the clock behaves exactly like the one above.
- Countdown Timer for Desktop
- Birthday Countdown Timer
- Retirement Countdown
- New Year Countdown
- Wedding Countdown
- Cruise Countdown
- Vacation Countdown
Counting minutes instead of days? The presets at the top of this page put one on screen in a click. For a repeating work timer or a count-up, the Pomodoro timer and stopwatch are the better tools, and both fill the screen the same way.
Back to Countdown IdeasFull screen countdown FAQ
Quick answers to the most common fullscreen countdown questions.
How do I display a timer on my screen?
Pick one of the minute presets at the top of this page — 5, 10, 15, 30 or 60 — and the timer starts and takes over the screen in the same click. For anything longer, set a date instead and use the fullscreen button on the clock. It is a web page either way, so any screen with a browser can show it: a projector, a TV, a second monitor, or a tablet propped up on a desk.
How do I make a countdown clock full screen?
Create your countdown, then click the fullscreen button in the bottom-right corner of the clock. The timer expands to fill the whole display — digits scale up, and your background color covers the entire screen. Press Esc to come back out.
Is there a free big countdown timer online?
Yes — this one. There's no signup, no watermark, and no time limit on how long you leave it running. Set a date, hit fullscreen, and leave the tab open as long as you need it.
Will the fullscreen button cover the countdown?
No. The button fades out after about two seconds of no mouse movement, so nothing sits on top of the digits while the clock is on display. Move the mouse or tap the screen and it comes back.
How do I get a birthday countdown timer full screen?
Build the countdown on the birthday countdown page, then use the same fullscreen button on the clock. The birthday page gives you birthday-specific templates; fullscreen works identically on every countdown across the site.
Can I put the countdown full screen on a second monitor or a TV?
Yes. Drag the browser window to the monitor or TV you want, then click fullscreen — it fills that display and leaves your main screen free. It works the same when casting a tab or plugging into a projector.
Do I need to download or install anything?
No. This is a web page, not an app, so there's nothing to install and nothing to keep updated. Any browser on any device can open it, including the smart TV or media player already attached to a display.
Does the full screen countdown work on a phone or tablet?
Yes. The fullscreen control works on mobile browsers too, and the layout scales to the screen. Tap the clock to bring the control back if it has faded out.
Can I set a timer for a few minutes rather than a date?
Yes. The presets at the top of the page do exactly that: one click sets the clock to 5, 10, 15, 30 or 60 minutes from right now and takes it fullscreen. The count runs in your browser, so nothing is saved and nothing is shared unless you choose to. For a repeating work timer or a count-up instead, the Pomodoro timer and the stopwatch are the better fits, and both go fullscreen the same way.
Is there a free full screen timer online?
Yes — this page is one. Pick a preset or a date, click fullscreen, and the timer fills the whole display. There is nothing to download and no account to make, so it works the same on a classroom PC or a borrowed laptop as it does on your own machine.
How do I exit full screen?
Press Esc, or move the mouse and click the same corner button again. Nothing about your countdown changes — you can go back into fullscreen whenever you like.
