title: Scraping different date formats with one line of RegEx
body: <p>I'm busy scraping this page on <a href="https://airwars.org/coalition-civcas-2017-sept/" rel="nofollow noreferrer">airwars.org</a> with Outwit hub and it's a mess.</p>
  
  <p>I would like to scrape all the dates but they're formatted differently:</p>
  
  <ul>
  <li>September 4th 2017</li>
  <li>September 5th – 6th 2017</li>
  <li>September 6th-7th 2017</li>
  <li>September 8th/9th 2017 </li>
  </ul>
  
  <p>The first one is <code>September \d+[a-z]+ 2017</code> but how do I target them all in one line of RegEx?</p>
