Abstract: The invention relates to a calendar comprising pages for calendar information, illustrations and text, where the pages are attached together so that by turning a page, the next page is advantageously revealed. In the pages (3) containing calendar information, the calendar section (5) proper and the section (6) containing illustrations and/or text can be detached from each other. Moreover, the calendar may contain pages provided with other than calendar information, as well as a binding which is essentially of the same size as the section (6) remaining after the calendar information (5) has been removed. After the period of active use, the calendar can be used as a book.
