I try to pass a String: "2.10.2017 - 15.10.2017" into a Calendar as the period of this appointment. To do this, i split this string into two strings, remove all spaces and store it in two strings this is working fine, but if i try to convert this two strings into two date objects, my startdate is right but my enddate is completely different to the actual date. Here is my Code what i tried:

 String date = "2.10.2017 - 15.11.2017";
            if (date.contains("-")){
                String[] parts = date.split("\\-");
                String part1 = parts[0].trim(); // 004
                String part2 = parts[1].trim(); // 034556
                Calendar startcal = Calendar.getInstance();
                Calendar endcal = Calendar.getInstance();
                DateFormat df = new SimpleDateFormat("dd.MM.yyyy");
                try {
                    startcal.setTime(df.parse(part1));
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                DateFormat dd = new SimpleDateFormat("dd.MM.yyyy");
                try {
                    endcal.setTime(dd.parse(part2));
                    Toast.makeText(getApplicationContext(),"Part2"+part2,Toast.LENGTH_LONG).show();
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                setupcalendar(startcal,endcal);
            }else {
                Calendar startcal = Calendar.getInstance();
                Calendar endcal = Calendar.getInstance();
                DateFormat df = new SimpleDateFormat("dd.MM.yyyy");
                try {
                    startcal.setTime(df.parse(date));
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                try {
                 endcal.setTime(df.parse(date));
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                setupcalendar(startcal,endcal);
            }

        }
    });
}
private void setupcalendar(Calendar startcal, Calendar endcal) {
    Calendar cal = Calendar.getInstance();
    Intent intent = new Intent(Intent.ACTION_EDIT);
    intent.setType("vnd.android.cursor.item/event");
    intent.putExtra("beginTime", startcal.getTimeInMillis());
    intent.putExtra("allDay", true);
    intent.putExtra("rrule", "FREQ=YEARLY");
    intent.putExtra("endTime", endcal.getTimeInMillis());
    intent.putExtra("title", data.get("name"));
    startActivity(intent);
}

in this example i received this enddate: 26.09.2017. I dont know why regards
