800 hours
The 800-hour online timer shows how much time is left until the end of the countdown, and allows you to start, pause, and reset it with a single click. When it reaches zero, an audible notification will sound, which you can change or disable.
The built-in time calculator converts 800 hours into days, minutes and seconds, making it easier to understand the duration. If necessary, the timer can be expanded to the full screen. The responsive design allows you to use it on any device, from a smartphone to a computer.
