duration
This term carries a clinical or technical tone, focusing on the precise measurement of a time span from start to finish. It is frequently used in legal contracts, travel itineraries, and scientific reports to establish a hard boundary of time. While "length" is a more general term for distance or time, "duration" specifically emphasizes the persistence of a state or the continuous flow of an event. It suggests a fixed window of time that must be completed or endured.
Countable when referring to specific measured intervals (e.g., different durations of a movie). Uncountable when referring to the general concept of how long something lasts.
