title: Is there a way to parse a relative date using Moment.js?
body: <p><a href="http://momentjs.com/" rel="noreferrer">Moment.js</a> is a very usefull JavaScript library which provides many functions to manipulate date formatting.</p>
  
  <p>In order to create a Moment object, it is possible to <a href="http://momentjs.com/docs/#/parsing/" rel="noreferrer">parse a string</a> simply <code>moment("1995-12-25");</code> or by providing format <code>moment("12-25-1995", "MM-DD-YYYY");</code>.</p>
  
  <p>Another feature allows us to use <a href="http://momentjs.com/docs/#/displaying/fromnow/" rel="noreferrer">relative dates</a> : <code>moment("1995-12-25").fromNow() // 19 years ago</code>.</p>
  
  <p>However, I can not find a way to parse such a relative date. When I try <code>moment("19 years ago")</code> it just returns <code>Invalid date</code>, and it does not exist any token to properly format the date.</p>
  
  <p>Is there an easy way to do this? Or is it a missing feature that should be suggested on Github?</p>
