How the countdown works
The countdown uses the clock on your device and updates every second. If 8:40 AM has already passed today, it counts down to 8:40 AM tomorrow. 8:40 AM is 08:40 in 24-hour (military) time.
Whether you want to know how long till 8:40 AM or just need a countdown to 8:40 AM 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.
