title: Query upcoming birthdays
body: <p>I'd like to query my customers for the ones, whose birthdays are yet to come.</p>
  
  <p>I've tried this query, and it - of course - has failed breathtakingly:</p>
  
  <pre><code>Addresses.Where(adr =&gt; adr.DateOfBirth != null &amp;&amp; adr.DateOfBirth.Value &gt;
  DateTime.Now).Take(15).ToList();
  </code></pre>
  
  <p>Of course this can't work properly (not if you're born in the future) and I'd like to know how I can query my <code>Nullable&lt;DateTime&gt;</code> without a year?</p>
