Not hanging washing out on a Sunday does have a religious connotation, as many Presbyterian Scots formerly held Sunday as strictly as a day of rest as observant Jews hold the Sabbath.
The ten commandments state that no work is to be done on the Sabbath, which was of course Saturday, when Exodus was written.
In Scotland the Sabbath just moved to The Lord's Day - there was nothing more dreary than a Scottish Sunday in my childhood. My grannie only served cold food, cooked on Saturday, no reading except the Bible or a religious book, two church services, no music, radio, tv , so obviously no-one did a washing on a Sunday.
Have you ever been to see a Spiritualist
