nux denotes the nighttime period, including literal events after dark and contrasts with day or light.

The noun most often marks the nighttime setting or duration of an action, whether a particular night, a watch or hour within it, or repeated activity “night and day.” In a smaller set of clauses, it is set against day, light, or the ability to work, including statements that night will not be present.

   Genitive and dative singular forms locate actions during the nighttime period: in Acts 12:6 the APB renders Peter's imprisonment scene as occurring “On the night before” Herod's action, while Acts 16:9 places Paul's vision “during the night.” The same noun marks duration or repeated activity in Luke 5:5, where Simon labored “all night,” and in 1 Thessalonians 2:9, where labor is described as “night and day.”
