title: Having issue with May Month in Classic ASP using CDate
body: <p>We have created a date converter in April month, <br>
  Which was working great until 30th April, But now it's not working.</p>
  
  <p>Issue happen when month change to May, <br>
  Here is my code with static data.</p>
  
  <pre><code>thisMonth = Month(CDate("April 29, 2017"))
  </code></pre>
  
  <p>This is working, But if I add month May,</p>
  
  <pre><code>thisMonth = Month(CDate("May 1, 2017"))
  </code></pre>
  
  <p>It's giving me following error,</p>
  
  <blockquote>
    <p>Microsoft VBScript runtime<br>
    error '800a000d'<br>
    Type mismatch: 'CDate'</p>
  </blockquote>
  
  <p>This is really strange behaviour.</p>
  
  <p>By the way, this is in the API.</p>
