Dictionary Definition

deadline n : the point in time at which something must be completed

User Contributed Dictionary



The context of a due date originated in journalism, probably from an earlier usage in printing, representing a guideline marked on a plate for a printing press (inside which all content should appear). According to the Oxford English Dictionary, early usage refers simply to lines that do not move, such as one used in angling; slightly later American usage includes a boundary around a prison which prisoners must not cross.
