EN

Date date = new Date();
LocalDate localDate = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
int month = localDate.getMonthValue();

java.util.Date date= new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
int month = cal.get(Calendar.MONTH);

//convert date to datetime
DateTime datetime = new DateTime(date);
int month = Integer.parseInt(datetime.toString("MM"))

int month = dateTime.getMonthOfYear();
