+<p>The datepicker can show the week of the year. The default calculation follows
+ the ISO 8601 definition: the week starts on Monday, the first week of the year
+ contains the first Thursday of the year. This means that some days from one
+ year may be placed into weeks 'belonging' to another year.</p>
