My Mum also had set days for doing things when we were children, eg, Monday was wash day as it used to take most of the day (no automatic washing machines for us back then, but a wash tub with a spinning tub alongside it - hard physical work).
Tuesday would be ironing day, not sure what Wednesday was, but no doubt something like window cleaning. Thursday was dusting & vacuuming throughout the house, Friday was “town” day to go to the market for fish, fruit & veg and possibly material if Mum was making some clothes for us. Saturday was baking day and Sunday was prepping and cooking Sunday lunch (dinner) for 2 pm, and later prepping tea. She allowed herself a little rest to read, too.
In between times were daily visits to the shops for bread, supermarket essentials, pay the papers bill or other bills, etc, (Not milk, we had that delivered).
It makes me feel exhausted just relating to you what she did 😲😁.
I don’t have set days for most things, but do tend to change the bedding on a Thursday. Washing gets done as and when there’s a load (the beauty of the automatic washer). I think that’s the thing nowadays, certain tasks don’t take all day to complete like they used to do, so we can be more flexible as to when we do them, owning a car means trips to the supermarket can be whenever we need to go. Mum never had a car, so daily trips to the shops were necessary due to the need to carry the shopping by hand, not being able to load it all into the boot of a car in one trip.
