title: Need week number of year in SSRS 2008
body: <p>hoping someone can help -- Googling provided none.  I need to get the week number (of the year) from a date.  I've added field "week_num" to my dataset and when I went to create the expression, I see there is no "WEEK" function under Date/Time?</p>
  
  <p>In VB and other languages there is a simple week function but I don't see it in SSRS 2008.  For example, if the date is '2014-03-16', I want the week number, which is 12.</p>
  
  <p>can anyone help?</p>
