A week is a unit of time longer than a day and shorter than a month. In most modern calendars, including the Gregorian calendar, the week is a period of seven days. Although having no direct astronomical basis, it is widely used as a unit of time, especially in the social and commercial context.
Weeks can be thought of as forming an independent continuous calendar running in parallel with various other calendars. However, some novel calendars have been designed in which the weeks and years are forced into synchronization by adding a leap week or weekless days into the calendar. The advantage of these calendars is that a given date always falls on the same day of the week every year. For example the proposed World calendar has 52 weeks and 1 or 2 extra days each year, while the French Revolutionary Calendar had 36 weeks of 10 days and 5 or 6 extra days. Alternatively, instead of adding extra days outside of weeks, it is possible to add entire weeks to the calendar if the years are allowed to vary in length —: the former Icelandic calendar had years of 52 or 53 weeks.
