Etymology

The word "weekday" is a transparent compound formed from two native English words. "Week" originates from a Proto-Germanic root meaning a sequence or change, which evolved to denote the specific seven-day cycle. "Day" stems from a common Germanic term for the 24-hour period of daylight. The compound's logic is directly literal, designating a day that belongs to the ordinary working sequence of the week, in contrast to the day of rest (originally Sunday, later including Saturday). Its meaning reflects the societal structuring of time into periods of labor and respite.
