Get month from the date

Hi Team,

I am trying to get the month, day and year from the date time. I was able to filter the records using a query, but the result is in a list type variant. 

I am unable to apply month/day functions to the fv!item.

If i write month[fv!item] i am getting the following error.

"Expression evaluation error at function a!forEach [line 47]: Error in a!forEach() expression during iteration 16: Expression evaluation error at function 'month' [line 56]: A null parameter has been passed."

I believe it is because each individual item is itself a list.

I don't know how to drilldown the list.  fv!item[1] give me another error. 

"Expression evaluation error at function a!forEach [line 47]: Error in a!forEach() expression during iteration 1: Expression evaluation error : Invalid index: Cannot index type Number (Integer) into type Date and Time".

Any help is appreciated. thanks
