The following Scripted Field code is throwing an error,

def month = doc['signed\_date'].date.monthOfYear;

I want to extract the months as a separate column. What am I doing wrong here?

Kindly help.

`monthOfYear` is not a function that is available in painless. You can access date pieces with the functions at [https://www.elastic.co/guide/en/elasticsearch/painless/master/painless-datetime.html#\_datetime\_pieces](https://www.elastic.co/guide/en/elasticsearch/painless/master/painless-datetime.html#_datetime_pieces).

`doc['timestamp'].value.getMonthValue()` is an example of a scripted field that returns the month of the year from the Kibana's web logs sample data set.

If you want the month as a string instead of a number, you could use `doc['timestamp'].value.getMonth()`. That method is not listed in the docs but the docs say the datetime type is `ZonedDateTime` and looking at the [Java docs for ZonedDateTime](https://docs.oracle.com/javase/8/docs/api/java/time/ZonedDateTime.html) shows some additional getter methods not mentioned in the painless documentation.
