                val year: Int = today.get(Calendar.YEAR)
                val month: Int = today.get(Calendar.MONTH)
                val date: Int = today.get(Calendar.DATE)


                val dlg = DatePickerDialog(this, object: DatePickerDialog.OnDateSetListener{
                    override fun onDateSet(view: DatePicker?, year: Int, month: Int, dayOfMonth: Int) {
                        //month는 +1
                        Log.d("MAIN", "${year} /  ${month+1} /  ${dayOfMonth}")
                        dateSelectBtn.setText("${year} /  ${month+1} /  ${dayOfMonth}")
                    }

                }, year, month, date)
                dlg.show()
            }
