when does the work week start and end
Workweek and weekend 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 (American 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 Saturday and Sunday. A weekday or workday is any day of the working week. Other institutions often follow the pattern, such as places of education.
Sunday For most observant Christians, Sunday is observed as a day of worship and rest, holding it as the Lord's Day and the day of Christ's resurrection. In some Muslim countries and Israel,[citation needed] Sunday is the first work day of the week. According to the Hebrew calendars and traditional Christian calendars, Sunday is the first day of the week.[1] According to the International Organization for Standardization ISO 8601, Sunday is the seventh day of the week.[2]
