5 hours
An online timer for 5 hours displays the remaining time and helps you control long classes or work sessions. The built-in converter immediately shows how many 5 hours are in minutes and seconds. Start, pause, and reset are performed with a single click. At the end of the timer, a beep sounds, which can be replaced or disabled.
