Scripting help- getting the date in yyyy-mm-dd format

[chidanandadhath]

I have the below script where I'm getting first and last date of the month but not in yyyy-mm-dd format, 

var nowDateTime = new GlideDateTime('2019-05-10');
var date = nowDateTime.getDate();
var month = date.toString().split("-")[1];
var year = date.toString().split("-")[0];
var FirstDay = new Date(year, month-1, 1);
var LastDay = new Date(year, month, 0);
gs.info(FirstDay);
gs.info(LastDay);

Output:

*** Script: Wed May 01 2019 00:00:00 GMT-0700 (PDT)
*** Script: Fri May 31 2019 00:00:00 GMT-0700 (PDT)

Please follow my blog here (Secrets of GlideDateTime) which outlines how to format date and times in any format.

Hi Paul, 

I modified the script as below

var nowDateTime = new GlideDateTime('2019-05-10');
var date = nowDateTime.getDate();
var month = date.toString().split("-")[1];
var year = date.toString().split("-")[0];
var FirstDay = new Date(year, month-1, 1);
var LastDay = new Date(year, month, 0);
gs.info(FirstDay);
gs.info(LastDay);

var newDate = FirstDay;
var gdt = new GlideDateTime();
gdt.setDisplayValue(newDate, "E, MMMM dd, yyyy K:mm a");
var dateTimeForField = gdt.getDisplayValue();
gs.print(dateTimeForField);

but I'm getting error as below

Evaluator: java.lang.RuntimeException: Unparseable date: "Wed May 01 2019 00:00:00 GMT-0700 (PDT)"

Also, GlideDate has the following methods:

getMonth ()

getYear ()

getDay()

I want to get first day and last day by passing date of the month, which I'm getting but not in required format
