Groovy - Working Days Calculation (JMCF)

I am using JMCF to create a custom field (calculation of working days between two dates). Here's the script I'm using:

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.user.util.UserManager;
import com.atlassian.jira.issue.MutableIssue
import java.util.Date.*
import java.text.DateFormat;
import java.text.SimpleDateFormat;

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
def startDate = issue.get("Travel Date From")
def endDate = issue.get("Travel Date To")

Calendar cal1 = Calendar.getInstance();
Calendar cal2 = Calendar.getInstance();

def numberOfDays = 0;
while (cal1.before(cal2)) {
if ((Calendar.SATURDAY != cal1.get(Calendar.DAY_OF_WEEK)) && (Calendar.SUNDAY != cal1.get(Calendar.DAY_OF_WEEK))) {

return (numberOfDays + " Working Days")


While the above script calculates the difference correctly for some dates, it shows wrong values for others.

Example 1: 1/Dec/20 - 6/Dec/20 - shows 4 working days - CORRECT

Example 2: 6/Dec/20 - 10/Dec/20 - shows 3 working days - INCORRECT (should be 4 days)

Is there anything wrong with the script? I can't figure out why the calculations are sometimes correct and sometimes not.

I need the values to show me the number of working days between two dates including start date and end date.

Any help would be much appreciated :)

Hi @Krzysztof Kiser  That's because the "before" is not including the last day.

In your first example, its not an issue because your end date is on Sunday.

So , I would recommend to add an extra day on the end date

@Gustavo Félix  thank you for noticing this. I am new to writing this sort of scripts, so I really didn't catch that.

I've amended the endDate to

def endDate = issue.get("Travel Date To")+1

and it now works fine.

Thanks again. Cheers!

HI @Krzysztof Kiser 

A much simpler script is available here in JMCF articles:
