Hey this is how to set alarm on android AlarmManager to spesific date (android alarmmanager set alarm on date) I have been searching all over for this. pay attention to the value of the month!!

Calendar cal = Calendar.getInstance(TimeZone.getDefault(), Locale.getDefault());
//cal.add(Calendar.SECOND, 10);

cal.set(Calendar.DATE,19);  //1-31
cal.set(Calendar.MONTH,Calendar.DECEMBER);  //first month is 0!!! January is zero!!!
cal.set(Calendar.YEAR,2012);//year...

cal.set(Calendar.HOUR_OF_DAY, 16);  //HOUR
cal.set(Calendar.MINUTE, 39);       //MIN
cal.set(Calendar.SECOND, 10);       //SEC


// Create a new PendingIntent and add it to the AlarmManager
Intent intent = new Intent(MainActivity.this, alarmAct.class);
PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0,intent, 0);

//or if you start an Activity
//PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0,intent, 0);

AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
