ScriptRunner - find number of days between two custom date fields

[Cynthia Parenteau]

Please help. I need to look at two custom date fields and find the number of days between them.  

I've tried multiple ways and times, to get this to work and I've found things on the internet that say this is a 3 line script - others that seem like endless code ?!?!?! What am i missing? Do i need to define more "components" first?  See screen shots below. 

Any help much appreciated.

The code you have written won't work, here is a snippet that should get you close to the solution, as you need to first get the custom field object and then use this object to get the value from the issue's date custom field

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import  java.util.Date.*

def customFieldManager = ComponentAccessor.getCustomFieldManager();
def dateFieldObject= customFieldManager.getCustomFieldObject('customfield_11601');

def dateFieldObject2= customFieldManager.getCustomFieldObject('customfield_11602');

if(issue.getCustomFieldValue(dateFieldObject) && issue.getCustomFieldValue(dateFieldObject2)) {
def dateValue=  issue.getCustomFieldValue(dateFieldObject) as Date
def dateValue2=  issue.getCustomFieldValue(dateFieldObject2) as Date
return dateValue - dateValue2
}

A very similar question and answer is here - 

https://community.atlassian.com/t5/Answers-Developer-Questions/Groovy-Scripted-Field-to-compare-dates/qaq-p/540301  (instead of minutes you can easily divide by 48 to change it into number of days)

Hi Tarun,

I want to calculate no of weeks from start date to end date.

Your script is giving no. of days between start date and end date.

How can we get no of weeks from it.
