title: Date.parse() doesn't work in IE 8
body: <p>Simple function <code>Date.parse()</code> not working well in <strong>Internet Explorer 8</strong>.<br>
  I am using <code>Date.parse()</code> to validate date in format <code>"MM/DD/YYYY"</code>.</p>
  
  <ul>
  <li><code>_.isNaN(Date.parse("99/99/9999"))</code> return <code>true</code> - date is invalid  </li>
  <li><code>_.isNaN(Date.parse("01/01/1990"))</code> return <code>false</code> - date is valid  </li>
  </ul>
  
  <p>But now I tried my JavaScript in IE 8 and I'm confused.  </p>
  
  <ul>
  <li><code>"88/88/8888"</code> - for this date all working well - date is invalid.</li>
  <li><code>"13/35/2012"</code> - invalid date
  but <code>Date.parse("13/35/2012")</code> parse this date in IE only and don't return <code>NaN</code>. </li>
  </ul>
