How the countdown works
The countdown uses the clock on your device and updates every second. If 5:15 PM has already passed today, it counts down to 5:15 PM tomorrow. 5:15 PM is 17:15 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.
