title: DST in JavaScript
body: <p>How can I check in JS file whether current Date is in DST or not?</p>
  
  <p>In C# there is the below code available to check this. Can anyone suggest similar code in JS?</p>
  
  <pre><code>var timezone = TimeZone.CurrentTimeZone
  var tzById = TimeZoneInfo.FindSystemTimeZoneById(timezone.StandardName);
  var localDate = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, tzById);
  </code></pre>
