286 hours
The 286-hour online timer starts with a single tap and counts down every second with high accuracy. The built-in converter instantly shows the remaining time in minutes, seconds and days, and the start, pause and reset buttons work in one click. Full-screen mode and a customizable beep sound help you focus on a long interval.
The interface automatically adapts to smartphones, tablets, and computers. The timer continues working correctly in the background when switching tabs, and the remaining time is displayed in the page title, so that you always keep the process under control.
A long 286 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.
