35 hours
An online timer counts down to zero for 35 hours. The built-in converter automatically converts 35 hours to seconds, minutes, and days. The interface is clear: the start, pause, and reset buttons are close at hand, and the full-screen mode removes distracting details. You can configure or disable the end sound completely.
The interface adapts to any screen and keeps working when changing tabs. The remaining time is duplicated in the browser header, which is useful when multitasking.
