title: How to get birthday via Facebook API?
body: <p>I am setting up a Facebook login, and am successfully getting things like <code>first_name</code>, <code>email</code>, etc. However, I cannot seem to figure out how to get birthday. If I call for <code>birthday</code> as below, nothing returns.</p>
  
  <pre><code>FB.api('/me', {fields: 'birthday'}, function(response) {
    console.log(JSON.stringify(response));
  })
  </code></pre>
  
  <p>If I call <code>user_birthday</code> as below, I get this error: <code>"error":{"message":"(#100) Tried accessing nonexisting field (user_birthday)</code></p>
  
  <pre><code>FB.api('/me', {fields: 'user_birthday'}, function(response) {
    console.log(JSON.stringify(response));
  })
  </code></pre>
  
  <p>How do I do this?</p>
