Changing Demonstrated Texts (Strings) of DatePicker in JavaFX

I would like to change some of the values ​​shown DatePicker

in JavaFX

.

For example, take a look at the image below:

If I want to change the color and text of the DateCell

current date, it seems very simple, because you can do it with the code below:

private DatePicker dateTest = new DatePicker();
final Callback<DatePicker, DateCell> dayCellFactory = new Callback<DatePicker, DateCell>()
        {
            public DateCell call(final DatePicker datePicker)
            {
                return new DateCell()
                {
                    @Override
                    public void updateItem(LocalDate item, boolean empty)
                    {
                        super.updateItem(item, empty);

                        if (MonthDay.from(item).equals(MonthDay.of(9, 13)))
                        {
                            setTooltip(new Tooltip("It going to be change"));
                            setStyle("-fx-background-color: #ff4444;");
                            setText("Elyas");
                        }
                        if (item.equals(LocalDate.now().plusDays(1)))
                        {
                            // Tomorrow is too soon.
                            setDisable(true);
                        }
                    }
                };
            }
        };
  dateTest.setDayCellFactory(dayCellFactory);

      

        
        
        
      

    

the result of the above codes becomes something like this:

so that you can see the text and color change DateCell

(in this case the 25th from September) is not very difficult.

but my question is, how can I change the other part DatePikcer

? For example, I would like to change

"September" to "Hello"

"sun" to "1"

"mon" to "2"

"2013" in "container of the year"
