Multihour

Multihour is an adjective used to describe something that lasts for more than one hour. In many contexts, the more common hyphenated form multi-hour is preferred in formal writing, while multihour appears in less formal usage or as a label in data templates or scheduling tools. The term is used across several domains where duration is a key attribute, including broadcasting, event planning, transportation timetables, and data collection.

In broadcasting, a multihour block refers to programming that extends over several consecutive hours, such as a late-night news block or a feature event. In scheduling and operations, multihour shifts or multihour windows indicate time spans longer than an hour, often crossing traditional day boundaries. In research or data collection, multihour experiments or observations involve measurements taken over a sustained period.

Ambiguity and style: because “multihour” describes any duration beyond one hour, it is imprecise without a specific length. When precision is important, durations should be stated explicitly (for example, “two hours” or “three hours”).

Etymology: the prefix multi- plus hour; the term mirrors the broader pattern of English compounds formed with multi- to indicate duration. See also hour, duration, time block, shift, marathon.
