Free Online Countdown Timer

TimeMaster's countdown timer lets you set a timer for any duration and receive audio and visual alerts when time runs out. Whether you need a 5-minute cooking timer, a 30-minute study session, or a custom countdown for any purpose, our tool is always ready in your browser.

How to Set a Countdown

Enter your desired hours, minutes, and seconds using the input fields, or choose from quick presets (1, 5, 10, 15, 30, or 60 minutes). Click Start to begin the countdown. A circular progress indicator shows how much time remains visually. You can pause and resume at any time, or reset to start over. When the timer reaches zero, you will hear an alarm sound and see a browser notification if permissions are granted.

When to Use a Countdown Timer

• Cooking and baking — time your recipes accurately
• Study sessions — focus for a set period
• Exercise rest periods between sets
• Meditation and mindfulness practice
• Presentation and speech practice
• Game turn limits and quizzes
• Meeting and class time management

Benefits of Using a Timer

Research shows that working within a set time limit increases focus and reduces procrastination. Known as Parkinson's Law, work expands to fill the time available — by setting a countdown, you create a healthy constraint that drives efficiency. Our countdown timer helps you stay on track and makes time visible, turning abstract minutes into a tangible, measurable resource.
