title: custom long date format in moment js
body: <p>Is there a way to add a custom format code to moment for long dates based on locale?</p>
  
  <p>for example:</p>
  
  <p><code>moment().format("L")</code> </p>
  
  <p>is an existing format that will print the long date for the locale (including the year), but if I wanted to add my own that excluded the year like this:</p>
  
  <p><code>moment().format("LTY")</code> that just printed the month and day in a given locale.</p>
  
  <p>How can I do this?</p>
