I'll constantly harp on about taking a day of rest because whether mandated by God or not, it just makes sense. Especially for homemakers and parents of children still at home or those doing elder-care who are "on" 24/7. We need time to reset, restore, and renew ourselves.
One of my favourite lines from Downton Abbey is the Dowager Countess asking "What is a weekend?" The wikipedia article answers that too!
The weekend is that period of the week set aside by custom or law for rest from labor. In many countries it is Saturday and Sunday and often includes Friday night. This five-day workweek arose in America when labor unions attempted to accommodate Jewish Sabbath, beginning at a New England cotton mill and also instituted by Henry Ford in 1926; it became standard in America by about 1940 and spread among English-speaking and European countries to become the international workweek. China adopted it in 1995 and Hong Kong by 2006. India and some other countries follow both the international workweek and a more traditional Saturday half-workday and Sunday weekend. While Indonesia and Lebanon have the international workweek, most Muslim countries count Friday as the weekend, alone or with Thursday (all or half) or Saturday. Some universities permit a three-day weekend from Friday to Sunday. The weekend in Israel, Nepal, and parts of Malaysia, is Friday (all or half) and Saturday. Only the one-day customary or legal weekends are usually called "Sabbath".
So enjoy your weekend. Make part of it a Sabbath, or just a sabbath or just a change from the ordinary to help renew yourself.
