A shop window is the most valuable screen you own. A live countdown to a sale, an opening, or a launch is one of the few things you can put on it that changes every second and still reads clean from the street. Here's how to set one up on the hardware you already have.
Why the window still wins
People walk past a shop window with their phone in hand and their attention already spoken for. A moving number is one of the few things that reliably breaks that. A big live "days until Christmas" or "hours until doors open" counter running behind the glass creates a hook that people pause on and then look up at the sign.
Poster paper doesn't move. A static digital ad doesn't move. A live counter does. And unlike a video ad, it never feels like an ad.
The hardware you already have
You don't need signage hardware. Every screen you already own works.
- Any smart TV made in the last five years: the built-in browser opens the counter link and hits fullscreen from the menu.
- An Amazon Fire Stick, Chromecast or Apple TV: cast the browser tab from a laptop or phone in the back office. The counter renders at full 1080p or 4K.
- A Raspberry Pi 4 with Chromium in kiosk mode: under 100 euros and it will run unattended for weeks.
- An old laptop plugged into a TV via HDMI: fine as long as it stays on and the screensaver is disabled.
All of these serve the same webpage. Whatever's easiest for you is fine.
Setting up the counter
- Build the board on Countspace. Pick the target date and time, name the counter (e.g. "Christmas Sale"), and choose a background that reads well from a distance.
- Copy the public link.
- On the display device, open the link in the browser.
- Tap fullscreen. On a keyboard that's F11. On a TV browser it's usually in the menu.
- Disable the screen timeout in the device settings.
That's the whole setup. From opening the browser to full-screen counter running is under two minutes.

What to count down to
A few reliable retail angles:
- Black Friday: a "days to doors open" counter through November, switching to hours in the final week.
- Christmas Eve: a "days to last order" counter for local delivery through December.
- Boxing Day sale: a "hours to Boxing Day" counter that goes live at midnight on the 25th.
- Season launches: fashion drops, in-store events, product releases. Any moment worth waiting for.
- Grand openings: a "days until we open" counter is the single most effective way to pre-market a new location.
Running unattended for weeks
Once the display is set up, the counter runs from the device's clock. As long as the device stays awake and the browser tab stays open, the counter keeps ticking. A dropped internet connection doesn't stop the numbers.
Two habits keep it reliable:
- Restart the display every Monday morning. Sixty seconds of down time keeps the browser cache fresh and clears any memory leaks in older devices.
- Set a phone reminder for the day the counter zeroes out. That's when you switch the board to the next date.
One shareable link, one target date. When the season ends, point the same board at the next date without touching the display.
