Why Set a Timer for 1 Hour?
One hour is ideal for deep work sessions where sustained concentration is required. Cal Newport's research on deep work suggests that most people can sustain 1 to 4 hours of deeply focused work per day, and one-hour blocks are a practical way to structure that time. In cooking, one hour covers slow-simmered sauces, baked potatoes at 400°F, and many casserole recipes. For exam preparation, timed 1-hour practice tests build stamina and help students calibrate their pacing for the real thing.

How This Timer Works
Click Start and the countdown begins from 1 hour to zero. A circular progress ring shrinks as time passes, giving you a visual sense of remaining time without needing to read the numbers. When the timer reaches zero, an audio alert plays to notify you.
You can pause and resume at any time, switch to fullscreen for a distraction-free view, or toggle the sound alert on and off. The keyboard shortcuts Space (start/pause) and R (reset) allow hands-free control.
Everything runs locally in your browser using your device's clock. No account, download, or internet connection is needed after the page loads. You can switch to other browser tabs and the timer will continue running in the background.
