12uurs

12uurs, sometimes written 12-uurs, is the Dutch-language term for a duration of twelve hours. It is a compound formed from twaalf (twelve) and uur (hour), and is used in scheduling, event naming, and descriptions of time-bound activities. The term is commonly seen in Dutch-speaking regions, particularly the Netherlands and Flanders.

In practice, 12uurs functions as a descriptor for endurance formats in sports and for programming blocks that last twelve hours. In endurance disciplines, 12uurs formats may involve teams or individuals working to cover distance or complete tasks over a continuous twelve-hour period, often as relays or solo efforts. Typical domains include cycling, running, and motorsport, with variations in rules, pacing, and safety defined by the organizer.

In media or events planning, 12uurs can denote a programming block or event window that extends for twelve hours, such as a radio, streaming, or festival schedule spanning a daytime-to-night period or the reverse, depending on local convention.

The 12uurs concept is related to other time-based formats, such as 24-hour endurance events, but it tends to imply shorter durations, different pacing, and logistics. See also: 12-hour or 24-hour endurance formats; Dutch language compounding.
