Overview

Create a Countdown Timer That Matches the Job

A countdown timer should be easy to read from across a desk, a classroom, a meeting room, or a stage screen. This page keeps the timer setup and live output together so users do not set a countdown in one place and search for the result somewhere else.

Direct answer: Use Duration mode for a quick online countdown timer such as 5 minutes, 10 minutes, or 25 minutes. Use Event Date mode for a future date and time. The timer runs in your browser, can switch to fullscreen, and plays a generated local alarm when time reaches zero.

Use it for presentations, meetings, classrooms, study sessions, cooking, workouts, live streams, breaks, webinars, church services, and event countdowns. For stopwatch-style count-up timing, use the Stopwatch. For work/break cycles, use the Pomodoro Timer.

Can I countdown to a specific date and time?

Yes. Switch to Event Date mode, choose a future target date from the custom calendar, choose a time from the custom time picker, and press Start.

Does this countdown timer have an alarm sound?

Yes. When the countdown reaches zero, the page plays a short browser-generated alarm tone. The sound is generated locally and does not use copyrighted audio files.

Can I use the countdown timer fullscreen?

Yes. Press Fullscreen to enlarge the timer workspace for meetings, classrooms, events, projectors, workouts, or presentation screens.

Will the timer keep running if I switch tabs?

The timer calculates remaining time from the real target timestamp, so when you return to the tab it catches up to the current browser clock.

Can I pause and resume the countdown?

Yes. Press Pause to freeze the remaining time, then Start again to resume from that remaining duration.

Is this good for classroom countdowns?

Yes. The large display, Classroom theme, fullscreen option, and local alarm work well for tests, transitions, cleanup, group tasks, and timed activities.
