How to implement Persian Calendar

Is there any implementation of Persian calendar DatePicker on JavaFx?

There is no Persian chronology to use on DatePicker to achieve a Persian calendar

I have now developed a ready-to-use calendar picker which also offers a persian calendar. It was originally inspired by the nice work of Christian Schudt, but completely rewritten and enhanced. Just download my library Time4J-v4.20 (or later, available in Maven) and use this code demo:

CalendarPicker<PersianCalendar> picker = picker.persianWithSystemDefaults();

picker.setLengthOfAnimations(Duration.seconds(0.7));
picker.setShowInfoLabel(true);
picker.setLocale(new Locale("fa", "IR"));
picker.setShowWeeks(true);

picker.setCellCustomizer(
  (cell, column, row, model, date) -> {
    if (CellCustomizer.isWeekend(column, model)) {
      cell.setStyle("-fx-background-color: #FFE0E0;");
      cell.setDisable(true);
    }
  }
);

You can also set other properties like minimum and maximum date. Here an example image using Farsi language and a localized week model for Iran. You can navigate through all Persian months, years or decades (by clicking on the header) or jump to current date (by clicking on the footer).
