How the countdown works
The countdown uses the clock on your device and updates every second. If 6:40 PM has already passed today, it counts down to 6:40 PM tomorrow. 6:40 PM is 18:40 in 24-hour (military) time.
Whether you want to know how long till 6:40 PM or just need a countdown to 6:40 PM for the end of a shift, a class, a meeting, a cooking timer or a store opening, keep the page open and the timer keeps running.
