You could use Date::Calc's Days_in_Month function (or any other function that will tell you how many days there are in the current month) and code as follows: 
  if(($cur_day+7) > Days_in_Month($cur_year,$cur_month)){
    # its the last n-day of the month 'cause this day next week is in 
+next month
  }
