How we became weekly

We highly depend on the week, despite its artificiality. Why? Monday, Tuesday, Wednesday... the concept of days going by is something that feels part of our nature and lives. A day is made out of 24 hours, seven days then comprehend a week, and 52 weeks add up to a year, and like that, the concept of time that rules our lives just goes on and on. But here is the exciting catch within that cycle: while days, months and years are based on natural processes, "the week finds its foundation entirely in history." In this remarkable essay, David Henkin, a Professor of History at the University of California, Berkeley, explains how the week is the most artificial and recent of our time counts and delves deeper into why it's practically impossible to imagine our shared lives without it.
