title: Check the date is greater than 0001-01-01 in Moment.js
body: <p>I have a function which formats date using,</p>
  
  <pre><code>export function FormatDate(date: string) {
  if (date != null) {
      return moment.utc(date).format('DD MMM YYYY');
  }
  else
      return "";
  }
  </code></pre>
  
  <p>But the issue is that null dates are received as "0001-01-01" (DateTime Min value). how can I check it with moment js?</p>
  
  <p>Could not find a straight forward way to do it. Following code works, but it's ugly,</p>
  
  <pre><code>new moment("0001-01-01").format("DD MMM YYYY") == moment.utc(date).format("DD MMM YYYY")
  </code></pre>
  
  <p>The "date" I receive is in "/Date(-62135596800000)/" format.</p>
  
  <p>I tried, <code>moment.utc(date).isAfter("0001-01-01")</code> and it's not working as well, returns true.</p>
  
  <p>What is the best way to check serialized date is not the minimum date?  </p>
