About Countdown Timer

The Countdown Timer counts down from any duration you set — hours, minutes and seconds — and announces clearly when time is up. Set 5 minutes for tea, 25 minutes for a Pomodoro focus block, or 2 hours for an exam simulation.

You can pause and resume the countdown at any point, and reset it to start over. The remaining time is computed from your device clock, so the countdown stays accurate even when the browser throttles background tabs.

The timer runs completely in your browser — no account, no install, no ads interrupting your focus.

How to Use the Countdown Timer

  1. Enter hours, minutes and seconds for your countdown.
  2. Click Start — the remaining time updates every second.
  3. Pause and Resume as needed; when the timer reaches zero you'll see a clear "Time's up" alert.

Features

  • Any duration up to 99 hours
  • Pause, resume and reset controls
  • Accurate timing even in background tabs
  • Screen-reader-friendly completion announcement
