title: Hibernate query date compare on year and month only
body: <p>I need to grab some records from a table which has a Column <code>birthDate</code> which is a <code>Date</code>(without time). I need to filter records by comparing against year and month only. 
  For example I want all the users born on March of 1990. The day doesn't matter.</p>
  
  <p>How do you handle it?</p>
