What is the Countdown Timer?
A simple, fast, browser-based timer that works the moment you open it. Set a countdown for any duration and get an alert when it hits zero. Switch to stopwatch mode if you want to track elapsed time instead.
No downloads, no accounts, no ads — just a clean timer that stays out of your way.
How to Use the Countdown Timer
- Choose a mode — select Countdown Timer or Stopwatch from the mode buttons at the top.
- Set the duration — for countdown mode, enter the hours, minutes, and seconds you want to count down from.
- Start the timer — press Start. Use Pause to hold it and Reset to start over from the beginning.
Use Cases
- Work sessions — time a focused work block using the Pomodoro technique or any interval that suits you.
- Presentations — keep track of how long you’ve been talking without glancing at a clock.
- Cooking — set a quick countdown for anything that needs a timed reminder.
- Workouts — time exercise intervals and rest periods with the stopwatch.
- Meetings — give each agenda item a countdown so discussions stay on track.
- Classroom activities — teachers can display the timer during timed exercises or test sections.
Why Use This Countdown Timer?
Most system timers are buried in an app or require unlocking your phone. This tool opens instantly in any browser tab and stays visible alongside whatever else you’re working on.
Because it runs entirely client-side, it works offline once the page is loaded. No usage data is collected, and nothing about your timing sessions is sent anywhere.
