title: remove recognized date from string
body: <p>As input I have several strings containing dates in different formats like</p>
  
  <ul>
  <li>"Peter drinks tea at <strong>16:45</strong>"</li>
  <li>"My birthday is on <strong>08-07-1990</strong>"</li>
  <li>"On <strong>Sat 11 July</strong> I'll be back home"</li>
  </ul>
  
  <p>I use <code>dateutil.parser.parse</code> to recognize the dates in the strings.<br>
  In the next step I want to remove the dates from the strings. Result should be</p>
  
  <ul>
  <li>"Peter drinks tea at "</li>
  <li>"My birthday is on "</li>
  <li>"On  I'll be back home"</li>
  </ul>
  
  <p>Is there a simple way to achieve this?</p>
