title: Showing only ONE week (Opening hours, each week the same)
body: <p>I would like to know if it is possible to show only one week, to use this calendar for showing opening hours of a shop.<br>
  So :<br>
      - I don't want to show the day dates (only the day names) : OK<br>
      - I don't want to colorize the current day : OK<br>
      - I want the calendar display always the same week => I don't know how to do that...</p>
  
  <p>Have you got any idea ? Is it possible to do that ?</p>
  
  <p>Thanks a lot !</p>
