Quality time is an informal reference to time spent with love ones (e.g., close family, partners or friends) which is in some way important, special, productive or profitable. It is time that is set aside for paying full and undivided attention to the person/matter at hand. It may also refer to time spent performing some favored activity (e.g., a hobby). The opportunity to experience quality time, or the actual time available to enjoy quality time is often limited. However, this is outweighed by the importance, intensity or value attached to events or interactions which occur during quality time. Quality time therefore has a degree of emotional or social "quality" which other aspects of personal life may lack. Busy parents may also use the term to justify the limited amount of overall time they spend with their children.
