How to compare the day of a LocalDate in CriteriaBuilder

I have an entity that has a LocalDate field.

    @Entity
    @Table(name="feriado")
    public class Feriado implements Serializable{

      private static final long serialVersionUID = 1L;

      @Id
      @GeneratedValue(strategy = GenerationType.IDENTITY)
      private Long id;

      @NotNull
      @Column(nullable=false,unique=true)
      @Convert(converter=LocalDateConverter.class)
      private LocalDate feriado;

      @NotNull @Size(min=5,max=100)
      @Column(nullable=false,length=100)
      private String descricao;

      @Column(name="dia_fixo",nullable = false, columnDefinition = "TINYINT", length = 1)
      private Boolean diaFixo;

      // get and sets

   }

I'm doing a query using CriteriaBuilder and I need to filter the holiday attribute by day

CriteriaBuilder cb = entityManager.getCriteriaBuilder();

CriteriaQuery<Long> cq = cb.createQuery(Long.class);

Root<Feriado> root = cq.from(Feriado.class);

cq.select(cb.count(root));

//Parametros
List<Predicate> criteria = new ArrayList<>();

Predicate filtroData = 
    cb.equal(root.<LocalDate>get("feriado"), dia);

The doubt is exactly in the last line

Predicate filterData =         cb.equal (root.get ("holiday"), day);

How to get the holiday field only? That is, get the value of the getDayOfMonth () method of a LocalDate with the criteria?
