yes it is fix now
how fix button color problem now?

Since it is not a problem all the other months, it is not a problem, especially if I can disable empty buttons, but if you have a better solution, we will do it.
In Gregory and jalali calendars, instead of the first row, the last row is empty in some months

In the last column to the number 7 and in the first column to the number 1

In Gregory and jalali calendars, instead of the first row, the last row is empty in some months

i answer that in #123 and #131

Is there a way to never have an empty row?

--- Update ---

like this

private void reflushWeekAndDay() {
 
            ye = (Integer) yearSpin.getValue();
            mo = (Integer) monthSpin.getValue();
            System.out.println("spinner ye " + ye);
            System.out.println("spinner mo " + mo);
 
            Locale ar = new Locale("ar");
            DateTimeFormatter dayOfMoonNum = DateTimeFormatter.ofPattern("d", ar);
            DateTimeFormatter dayOfweekNum = DateTimeFormatter.ofPattern("c", ar);
            HijrahDate hijrahDate = HijrahChronology.INSTANCE.date(ye, mo, da);
            HijrahChronology crono = hijrahDate.getChronology();
            HijrahDate date = crono.date(ye, mo, da);
            System.out.println("crono date= " + date);
            String MoondayNum = hijrahDate.format(dayOfMoonNum);
            String WeekdayNum = hijrahDate.format(dayOfweekNum);
            int WeekdayNumb = Integer.parseInt(WeekdayNum);
            int moondayNumb = Integer.parseInt(MoondayNum);
            int moondaysnumber = hijrahDate.lengthOfMonth();
            System.out.println("hijrahDate= " + hijrahDate);
            System.out.println("Number day-of-month   " + moondayNumb);
            System.out.println("Number day-of-Week   " + WeekdayNumb);
            System.out.println("Number of days of the month   " + moondaysnumber);
            int maxDayNo = moondaysnumber;
            System.out.println("Number of days of the month   " + moondaysnumber);
            int dayNo = -4 - WeekdayNumb;
//            int dayNo = 0;
            System.out.println("dayNo   " + dayNo);
            for (int i = 0; i < 6; i++) {
                for (int j = 0; j < 7; j++) {
                    String s = "";
                    if (dayNo >= 1 && dayNo <= maxDayNo) {
                        s = String.valueOf(dayNo);
                    }
                    daysButton[i][j].setText(s);
                    dayNo++;
                    if (daysButton[i][j].getText().equals("")){
                        daysButton[i][j].setVisible(false);
                        }
                }

in the #135 i solved button's visible problem but i cant fix JDialog Hight after empty button's visible false
In the calendar, day 1 can not always be in the last button, it must be in the desired day
In the last column to the number -6 and in the first column to the number 1

ok now how we can fix button's color? after use sppiner colors not working Properly

When I click on the button, that button should turn orange and the previous button should return to the default color, but as you can see in the picture, it does not work properly.
https://s18.picofile.com/file/8432135718/Capture.JPG

In this part of the code, it is said that if it was the last day of the week, the color of the text box would be red Otherwise the text color will be black

 if (j == 6) {
                        numBtn.setForeground(weekendFontColor);
                    } else {
                        numBtn.setForeground(dateFontColor);
                    }

When the button is clicked, its color changes to orange (today)

 numBtn.addActionListener(new ActionListener() {
                        public void actionPerformed(ActionEvent event) {
                            JButton source = (JButton) event.getSource();
                            if (source.getText().length() == 0) {
 
                                return;
                            }
                            dayColorUpdate(true);
                            numBtn.setBackground(palletTableColor);
                            numBtn.setForeground(dateFontColor);
                            source.setForeground(todayBackColor);
 
                            int newDay = Integer.parseInt(source.getText());
                            da = newDay;
 
                            setDate();
 
                            dateDialog.setVisible(false);
                        }
                    });

When the box is loaded today, it turns orange by default

int actionCommandId = moondayNumb + 3 + WeekdayNumb;
            int i = actionCommandId / 7;
            int j = actionCommandId % 7;
            if (isOldDay) {
                daysButton[i][j].setForeground(dateFontColor);
                daysButton[i][6].setForeground(weekendFontColor);
            } else {
                daysButton[i][j].setForeground(dateFontColor);
                daysButton[i][6].setForeground(weekendFontColor);
                daysButton[i][j].setForeground(todayBackColor);
            }

This is the output of the program
When the user clicks on a button what should happen? When I click on the button, that button should turn orange and the previous button should return to the default color, but as you can see in the picture, it does not work properly.
What if it is the first time a button was clicked? that button turn orang but previous button don't return to the default color
What if it is the second time a button was clicked? nothing
https://s18.picofile.com/file/8432135718/Capture.JPG

In the code, before applying the color to the new button, all the previous buttons are always told to change the state to the default color

 
        Color palletTableColor = Color.white;
        Color todayBackColor = Color.orange;
        Color dateFontColor = Color.black;
 
 
                            numBtn.setBackground(palletTableColor);
                            numBtn.setForeground(dateFontColor);
                            source.setForeground(todayBackColor);

The code is executed line by line, so first all the buttons are returned to the previous color, then the color of the button is changed today

--- Update ---

In other words, when you click on today, first every day changes to the default color, then today it turns orange.

--- Update ---

After a few clicks on the buttons, the color of the previous buttons will not return to the default state, and usually 7 of the buttons will always remain orange.
