A week is a time unit equal to seven days . It is the standard time period used for cycles of work days and rest days in most parts of the world, mostly alongside (but not strictly part of) the Gregorian calendar .
The days of the week were named in different languages after classical planets, various deities (example: Thursday – Thor's day, a variation after Jupiter's day from Roman times) and heavenly bodies (example: Sunday – Sun's day) and other sources. In English, the names are Monday , Tuesday , Wednesday , Thursday , Friday , Saturday and Sunday .
ISO 8601 includes the ISO week date system, a numbering system for weeks within a given year – each week begins on a Monday and is associated with the year that contains that week's Thursday (so that if a year starts in a long weekend Friday–Sunday, week number one of the year will start after that).
