Online countdown timer — set it, run it, hear it
Set hours, minutes, and seconds and press start: big full-screen numbers, the last ten seconds in red, a beep when it hits zero. The same site builds date countdowns and paste-anywhere embeds for your website — nothing is uploaded, ever.
05:00
ready
Tip: the last ten seconds turn red, and a beep sounds at zero — keep the tab unmuted. The timer anchors on your device clock, so it stays exact even in a background tab.

Free Countdown Timer — No Signup
Countdown timers with no account, no email, no install — why signup-free tools exist, what to check before trusting one, and how this site's timers work.
What this site does — and what it does not
It does
- Count down durations and dates with drift-proof timing anchored on your device clock.
- Generate embed code you can paste into any site builder — free, no watermark.
- Run everything locally: durations, dates, and embeds never touch a server of ours.
It does not
- Notify you when the tab is closed — a web page can't; installed apps can.
- Ask for an account — there isn't one, and there is no Pro tier either.
- Store your countdowns — reopen the page and it recomputes exactly from your clock.
