The workweek and weekend are those complementary parts of the week devoted to labour and rest, respectively. The legal working week (British English), or workweek (U.S. English), is the part of the seven-day week devoted to labour. In most Western countries it is Monday to Friday; the weekend is a time period including Saturday and Sunday. Some people extend the weekend to Friday nights as well. In some Christian traditions, Sunday is the "Lord's Day" and the day of rest and worship. In other Christian traditions, they recognize the solar calendar and their day of rest is from noon on Saturday to noon on Sunday[citation needed]. JewishShabbat or Biblical Sabbath lasts from sunset on Friday to the fall of full darkness on Saturday, leading to a Friday-Saturday weekend in Israel. Muslim-majority countries usually have a Thursday-Friday or Friday-Saturday weekend. The French Revolutionary Calendar had ten-day weeks (called décades) and allowed décadi, one out of the ten days, as a leisure day.
