404 hours
A 404-hour timer displays the remaining time with a nice counter and helps you control a long process. The interface is minimalistic: just a few buttons to start, stop, and reset the countdown. At the end of the countdown, a sound signal is activated, the volume of which can be changed or turned off altogether. The built-in time converter system shows the equivalent of 404 hours in days, minutes, and seconds.
The design is adapted to any device-from smartphones to wide screens. The ability to expand the timer to full screen makes it convenient to use in different situations. Even when switching pages in the browser, the timer continues to work, and the remaining time until the end is visible in the tab title.
A long 404 hours timer is convenient when you need to count down an extended interval — from several days to waiting for a major event. The countdown keeps running steadily even across tab switches.
