131 hours
The online timer counts down to zero for 131 hours. The built-in converter automatically converts 131 hours to seconds, minutes, and days.
The Start, Pause, and Reset buttons are available with a single click; full-screen mode expands the timer to full screen. Completion is accompanied by the selected sound — the volume can be easily changed or turned off. The timer continues to count down in the background tab, and the rest of the time is visible in the browser header.
