Hibernate: Unknown column in field list

I am getting the following error from my Hibernate code:

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Unknown column 'bulletin0_.bulletin_date' in 'field list'

There is no such bulletin_date column in my table, nor is there such a name in my model class. It's just called date. Here is the line where I'm getting the error.

Query query = session.createQuery("from Bulletin where approved = true");

Here is my model class (I'm leaving out the getters and setters):

public class Bulletin {
    @Id
    @Column(name="id")
    @GeneratedValue
    private int id;

    @Column(name="date")
    private String date;

    @Column(name="name")
    private String name;

    @Column(name="subject")
    private String subject;

    @Column(name="note")
    private String note;

    @Column(name="approved")
    private boolean approved;
}

Here is my table definition.
