📖 About the Countdown Timer
This online countdown timer lets you set any duration from seconds to hours and counts down to zero. When the timer finishes, you'll hear an alarm sound and see a visual alert. It's perfect for cooking, exercising, studying, presentations, meetings, or any activity that requires a timed session.
Choose from convenient presets (1, 3, 5, 10, 15, 25, 30 minutes, or 1 hour) or enter a custom duration. The timer continues running accurately even if you switch to another tab, and it updates the page title so you can see the remaining time in your browser tab.
❓ Frequently Asked Questions

You can set up to 99 hours, 59 minutes, and 59 seconds — that's over 4 days. This should be more than enough for any practical use case.
