Runtime get month()

[Murilo_Livorato]

hello , I have this runtime -

GET my-index-000006-test/_search
{
  "runtime_mappings": {
        "day_of_week": {
        "type": "keyword",
        "script": {
          "source": "emit(doc['timestamp'].value.dayOfWeekEnum.getDisplayName(TextStyle.FULL, Locale.ROOT))"
        }
      }
  },
  "fields" : ["day_of_week"]
}

Its gives the day of the week from the timestamp -

  {
        "_index": "my-index-000006-test",
        "_id": "tUF9rIkB6LNnmdzdzkzz",
        "_score": 1,
        "_source": {
          "title": "three",
          "timestamp": "2021-01-04"
        },
        "fields": {
          "day_of_week": [
            "Monday"
          ]
        }
      },

does have any how to get the Month of the year ? I tryed like that -

GET my-index-000006-test/_search
{
  "runtime_mappings": {
        "month_of_year": {
        "type": "keyword",
        "script": {
          "source": "emit(doc['timestamp'].value.getMonth()"
        }
      }
  },
  "fields" : ["month_of_year"]
}
