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 of the Western world it is Monday to Friday; the weekend is a time period including Saturday and Sunday. A weekday is any day of the working week. As well as places of work, other institutions often follow the same days, such as places of education.
