title: remove time HH:mm from String
body: <p>I need to check if a string is in the following format:</p>
  
  <pre><code>sunday, 31.01.2016 00:05 - wednesday, 03.02.2016 23:55
  </code></pre>
  
  <p>And then remove the time.</p>
  
  <p>Result should look like:</p>
  
  <pre><code>sunday, 31.01.2016 - wednesday, 03.02.2016
  </code></pre>
  
  <p>I tried a couple of things but I`m not good in regex or with slice and substring...</p>
