396 hours
Start the timer and keep track of the time without any extra effort. Large numbers show the remaining balance, and the Start, Pause, and Reset controls work in one click. You can replace or disable the ending melody.
The built-in time calculator instantly converts 396 hours to days, minutes, and seconds. The interface adapts to any screen and does not get lost in the background tab, duplicating the end time in the page title. Full-screen mode leaves only the timer on the screen, removing all unnecessary things.
