Hi Divya, This can be achieved by calculating days difference between current date and selected date. You need to write an on change client script on the date field, and call a script include to do difference check.

You need to use the Client SCript field onChange of the date field. Below is the validation script

var date_Value = newValue;

var gdt = new GlideDateTime(date_Value + " 00:00:00");
gdt.addWeeks(24);
var test = gdt.getDate();

if(dateValue > test) {
gs.print("Beyond");
}

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;

}

var datesplit = (newValue+'').split('-');
var date= new Date(datesplit[2],datesplit[1]-1,datesplit[0]);
var sixmonthdate = new Date();
var day = sixmonthdate.getDate();
sixmonthdate.setMonth(6);
//sixmonthdate.setDate(day+1); for increasing days in the same month
sixmonthdate.setDate(day);
if(date>sixmonthdate)
{
g_form.showFieldMsg('FieldName','You can only request an extension of up to 6 months maximum and cannot be extended on top of the users current expiry date','error');
}
}
