Week

A week is a unit of time equal to seven days. It is the standard calendrical period between a day and a month in most parts of the world. There are just over 52 weeks in a year, or on average 4+1⁄3 weeks in a month. The days of the week are often used to set work days, rest days, and holy days. The term "week" is also used to refer to a sub-section of the week, such as the workweek and weekend. Certain weeks within a year may be designated for a particular purpose, such as Golden Week in China and Japan. More informally, certain groups may advocate awareness weeks, such as National Family Week in Canada, which are designed to draw attention to a certain subject or cause.
