Can I put a countdown on a TV without installing anything?

Yes. Every modern smart TV, streaming stick and projector with a browser can open a Countspace link and display it fullscreen. Nothing to download, no account required.

Will the screen keep the countdown running for days or weeks?

Yes, as long as the device stays awake. Disable screen timeout on the TV or projector, keep the browser tab in the foreground, and the counter will tick indefinitely.

How do I get the counter into fullscreen mode?

On desktop and most smart TVs press F11 or the fullscreen icon in your browser. On Chromecast and Fire TV, cast the tab to the display. Countspace also has a built-in fullscreen button that hides all browser chrome.

What if the venue Wi-Fi drops?

Countspace keeps running from the browser's local time after the page has loaded once. The clock stays accurate even if the connection goes away for hours.

How to display a countdown on any TV or projector

The best countdowns live on a screen everyone can see. Not a phone. A TV in the shop window, a projector at a wedding, a tablet on the kitchen shelf. Countspace was built to make that easy without installing anything.

The one-link idea

Every countdown you build has a public link like countspace.app/b/your-countdown. That link is all you need. Open it in a browser on any device with a screen, hit fullscreen, and walk away. It keeps ticking in your timezone until the target date.

There's no app to install. No login on the display device. If the venue changes screens the next day, open the same link on the new one and pick up where you left off.

On a modern smart TV

Almost every TV made in the last few years ships with a browser. Some hide it behind an app store, but it's there.

Samsung, LG, Sony: the built-in web browser opens URLs directly. Type the link, tap fullscreen from the browser menu.
Chromecast, Google TV, Fire TV: open the countdown on your laptop or phone, then cast the tab to the TV. The counter renders at full resolution.
Apple TV: no built-in browser, but AirPlay from a Mac or iPad works the same way.

If the display keeps dimming, disable the screen timeout in the TV settings. Some models call this "screen saver" or "energy saving".

On a projector

A projector is just an external display. Plug in a laptop, an HDMI stick, or a small Chromecast, load the counter, go fullscreen. That's it.

For events where the projector runs for hours, prefer a device with active cooling. HDMI sticks tend to throttle or reboot when they get hot in a stuffy venue, which will interrupt the counter.

Kiosk / unattended mode

If the counter has to run for days or weeks without anyone touching the device, put the browser in kiosk mode.

Chrome on Mac or PC: launch with chrome --kiosk https://countspace.app/b/your-slug. Full screen, no browser UI, no way to accidentally close it.
Chromebooks: set the counter URL as a managed kiosk app in the admin console.
Raspberry Pi: a Pi 4 running Chromium in kiosk mode is a rock-solid unattended display for under 100€.

Combine that with the operating system's "prevent sleep" setting and the counter will keep going indefinitely.

Tips that catch people out

Set the target in the right timezone: Countspace stores the target as an absolute moment. If your event is at 9pm local time, that's the moment the counter zeroes out for anyone watching, no matter where they are.
Test the link on the actual display: some older TVs render fonts oddly. Five minutes of testing beats a live event surprise.
Turn off screen mirroring notifications: Chromecast and AirPlay can pop toasts that interrupt fullscreen. Enable "do not disturb" on the source device.
Pick a theme with real contrast: a bright projector in a bright room needs a high-contrast background. The forest and espresso themes work well here.
