Harold's code is more efficient than yours but it has a different logic... if you're interrested to know why your code didn't work here is a version that takes the same approach as yours but with a few bug corrections that make it work.

Shortly described, you pushed the value at a wrong place in the loop and you forgot to add a first item to have at least one element in your second array. You didn't use match the right way, match returns the 'common' part in the string, not a boolean.

Here is the code :

function myFunction() {
  var ss = SpreadsheetApp.getActiveSheet();
  var data = ss.getRange(2,2,ss.getLastRow(),3).getValues();
  var ListOfMonths = new Array();
  ListOfMonths.push(data[0])

  for(var i = 0; i < data.length; ++i){

    var row = data[i];
    var duplicate = false;

    for(j in ListOfMonths){
      var item = ListOfMonths[j][0];
      if(row.toString().match(item) == item){
        duplicate = true;
        break;
      }
    }
    if(!duplicate && i
