The Lord's Day, the Emperor's Decree and the Workers' Rest: The Evolution of the Holiday

This article explores the historical evolution of the weekly holiday from its religious origins to its establishment as a global labor standard. The study is divided into three major phases: (1) The Lord’s Day – originating in Judaism and later adopted by Christianity as a day of rest and worship, ultimately shifting from Saturday (Sabbath) to Sunday in honor of the Resurrection; (2) The Emperor’s Decree – beginning with Emperor Constantine the Great’s edict in A.D. 321, which declared “the venerable day of the Sun” a legal public holiday throughout the Roman Empire, marking the first official state-sanctioned day of rest; and (3) The Workers’ Rest – emerging during the Industrial Revolution, when Ford Motor Company, in 1926, instituted the five-day workweek with two days of rest (Saturday–Sunday), a model that soon spread worldwide. The findings reveal that the concept of the weekly holiday transcends labor policy it embodies the interconnection of religion, politics and economics, reflecting humanity’s transformation from an age of faith to an industrialized global society.
