  <p>How i can <strong>allocate weekend</strong> day? For example in <strong>red color</strong> is <strong>weekend</strong>, other <strong>days</strong> except <strong>weekends</strong> is <strong>blue</strong>. I means to <strong>allocate</strong> not <strong>day</strong> of the <strong>week</strong> (like a <strong>sunday, saturday</strong>), namely <strong>day</strong>, i.e. <strong>date</strong>:</p>
  
  <p>Monday is 0 - blue color</p>
  
  <p>Tuesday is 1 - blue color</p>
  
  <p>...</p>
  
  <p>Saturday is 5 - red color</p>
  
  <p>Sunday is 6 - red color</p>
  
  <p>Monday is 7 - blue color</p>
  
  <p>...</p>
  
  <p>Saturday is 12 - red color</p>
  
  <p>Sunday is 13 - red color</p>
  
  <p>and so on</p>
