The set day to do a specific thing was nationwide. As a child in the 50's in central US, we followed the same schedule. Ever get your fingers caught in the wringer? It's an experience that usually only happened ONCE! I can't remember what Friday was for but Saturday was cleaning house to be ready for the Sabbath. Although I'm a "city kid", I can remember visiting the farm and wondering how my grandmother did all that and still cooked for the farm hands, especially the huge noon dinner. I also have fond memories of watching my PD ggrandmother in the evenings. After supper was "cleared away", she'd sit in her favorite chair and crochet, night after night after night. Her hands were never idle. One didn't need a clock to know it was bedtime. All of a sudden she would put her crocheting away, check to see if the doors were locked, check the kitchen for the stray dirty dish and everyone knew it was time for bed. No questions asked! BG
