Countdown
Countdown is a process of counting backwards from a set time or date to zero. It's often used to signify an event or deadline, and the counting process usually involves visible or audible cues to signal the remaining time. Countdowns can be found in a variety of settings, from rocket launches to New Year's Eve celebrations to sports events. The purpose of a countdown is to build suspense and anticipation towards the event or deadline, and to help ensure that all involved parties are aware of the remaining time.
