Yep, I concur. As an atheist I am as detached from religion as you can get, and I still think this article has some valuable insight. I know it from experience, as I am from Germany and most workers actually do have Sundays off (there are exceptions of course: doctors, nurses, gas station workers, police officers...). In retrospective, I very much appreciated having it as a kid. My parents were pretty busy otherwise but Sundays were always different and brought us together as a family.
