320 minutes
A 320-minute timer provides an accurate countdown for long-running tasks. The built-in converter automatically converts 320 minutes to hours and seconds. Simple control buttons - Start, Pause and Reset - allow you to easily start and control the timer. You can adjust the volume of the end notification sound or turn it off altogether.
The timer interface adapts to any device and works correctly on both smartphones and desktops. Full-screen mode hides distracting elements and makes the tag more visible even on small screens. The timer continues to work accurately when switching between pages, and the remaining time is displayed in the tab title.
A long 320 minutes timer is useful for classes, trips, work shifts, slow-cook recipes, and any scenario where you need to time a long interval. The browser keeps the countdown accurate even when you switch tabs.
