About this Countdown Timer

Countdown Timer counts down from hours, minutes, and seconds you set—ideal for exams, presentations, cooking intervals, and launch drills. Students pace practice tests; hosts keep lightning talks honest; freelancers time workshop activities. Enter the duration, start the countdown, and optionally reset when scenarios change. The timer runs in your browser so classroom modes need no account. Pair with the meeting planner when the real constraint is a shared wall-clock time across zones rather than a simple duration. Leave the tab audible if you depend on the finishing alert. Display the timer to an audience during workshops for shared accountability. Prepare a backup phone timer when facilitators rely on flaky conference Wi-Fi. Stack multiple short countdowns rather than one opaque long block for agendas.

Can I run multiple countdowns?
Use separate tabs/windows if you need parallel timers.
