You have to use android AlarmManager.

Schedule a Receiver that will be fired at specific time as you needed and in onReceive write code for deleting from datbase

Set the alarm like

Intent intent = new Intent(context, AlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
                0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context
                .getSystemService(Context.ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, triggerTime, pendingIntent

);

and in the receiver write code for deletion

public class AlarmReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
        // code to delete from db
            }

    }
