title: Vba add border to row if date changes
body: <p>I have a large spreadsheet with up to 20 columns. The date is in column C. What I'd like to do is have a macro that adds a border to the last row of a date in order to separate rows into dates. Ie</p>
  
  <pre><code>2/2/15
  2/2/15
  2/2/15
  ______
  3/2/15
  3/2/15
  </code></pre>
  
  <p>I would also like the border to extend the width of the sheet. Also it may be important to note there may be larger gaps between dates than just the next day. </p>
