Countdown Clock — Large Digital Display for Any Deadline

Who this is for: For presenters, teachers, and event hosts who want the room to see the time remaining at a glance — on a projector, a TV, or a shared screen — without fiddling with settings.

Not the right tool for: Counting to a date on the calendar — use the date countdown for calendar targets · Stopwatch or count-up timing — this page only counts down

A large digital countdown clock for any deadline — projector-friendly digits, pause and resume, and an audible chime when time runs out.

Quick answer: A countdown clock displays the time remaining to a deadline in large digits the whole room can read. Set your duration below, press Start, and use the fullscreen button for projectors and TVs — a chime sounds at zero.

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.

How is a countdown clock different from a kitchen timer?

A countdown clock is built to be watched from a distance: the digits dominate the display, the last ten seconds change color so a whole room notices, and fullscreen mode removes everything else from view. Underneath it is the same honest mechanism — the clock reads your device's time, so it never drifts, and the end-of-time chime is generated by the browser itself with no audio files or permissions needed.

Common uses

  • Counting down to the start of a webinar, class, or ceremony
  • Keeping speakers inside their slot at conferences and debates
  • A shared deadline display for team rooms and hackathons
  • New Year's Eve and event warm-up screens

Frequently Asked Questions

Can I show this countdown clock on a TV?
Yes — open this page in the TV's browser (or cast your screen), set the duration, press Start, then tap the fullscreen button. The digits scale to fill the screen.
Does the clock keep running if I switch tabs?
Yes. It reads your device clock on every refresh of the display, so switching tabs, locking the screen briefly, or background throttling never shifts the end time.
Can I pause and resume the countdown?
Yes — Pause freezes the display, Resume continues from exactly where it stopped, and Reset returns to the setup state.
Is there a sound when the countdown clock reaches zero?
Yes, a clear three-beep chime. Keep the tab unmuted so it can play.
Do you store what I set?
No. The duration lives in the page in front of you; nothing is uploaded, stored, or shared.
