text: The ISO standard includes the ISO week date system, a numbering system for weeks within a given year, where each week starting on a Monday 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, and if, conversely, a year ends on a Monday, Tuesday or Wednesday, the last days of the year are counted as part of week 1 of the following year).
