Universal solution for a long countdown

An 856-hour counter helps you track long time intervals. The interface is simple and intuitive, and the start, pause, and reset buttons are conveniently located at your fingertips, but they don't distract you from the process. At the end of the countdown, a melody is played, which can be selected and configured separately. For convenience, there is a built-in translation of 856 hours into days, minutes and seconds.

The timer works stably on all devices and supports full-screen mode. When switching to another page, the countdown continues correctly in the background, and the current end time remains visible in the browser tab title.
