How do I make a birthday countdown for someone?

Type the person's name and pick the birthday date (you can add a time too), then press Generate link. You get a unique link like https://jasperbernaers.com/birthday-countdown/?name=Sarah&date=2026-08-12 that you can copy and send to anyone. When they open it, the retro flip-clock board counts down to that exact moment.

What visual themes are available?

Four themes: Flip Board (a retro split-flap departures display), Terminal Boot (a green CRT terminal countdown), VHS Synthwave (an 80s neon grid with REC overlay), and Arcade 8-bit (a pixel-art cabinet). Pick one with the Theme buttons or press T to cycle. The chosen theme is saved in the share link, so whoever opens it sees the same look.

How do I make the countdown fullscreen?

Press the Enter Fullscreen button or the F key and the board fills the whole screen — perfect for a TV, projector or second monitor at a party. Press ESC or F again to exit.

Can I change the colours?

Yes. Pick from 9 colour themes or a custom colour picker. The whole board — digits, headline and labels — recolours instantly. It works in fullscreen too, and you can switch with number keys 1 to 9. Your choice is remembered on your device.

What happens when the countdown reaches zero?

The board lands on all zeros and the page bursts into a full-screen confetti celebration with a big Happy Birthday message — it works in fullscreen too. It stays in party mode for the rest of the day.

Does the link store any personal data?

No. Everything lives in the URL itself — the name and date are just parameters in the link. Nothing is saved on a server, there are no accounts, and there is no tracking of who you make countdowns for.

Can I count down to an exact time, not just a date?

Yes. The optional time field lets you count down to an exact moment, such as a midnight surprise. The link gains a time=HH:MM parameter and the countdown always uses the viewer's local time zone.

Is this birthday countdown free?

Yes, completely free. No account, no subscription, no watermark, no ads. It is one of the free browser-based tools at jasperbernaers.com.
