How the countdown works
The countdown uses the clock on your device and updates every second. If 3:00 AM has already passed today, it counts down to 3:00 AM tomorrow. 3:00 AM is 03:00 in 24-hour (military) time.
Handy for timing the end of a work shift, a class, a meeting, a cooking timer or a store opening. Keep the page open and the timer keeps running.
