date interval calculation ignoring weekends in JIRA

I have a question related to an older post, see below. I would like to modify this to calculate the time between a custom field, "Reported" and the current date/time in JIRA.

<!-- @@Formula:long days(Date start, Date end) {
//Ignore argument check
Calendar c1 = GregorianCalendar.getInstance();
int w1 = c1.get(Calendar.DAY_OF_WEEK);
c1.add(Calendar.DAY_OF_WEEK, -w1 + 1);
Calendar c2 = GregorianCalendar.getInstance();
int w2 = c2.get(Calendar.DAY_OF_WEEK);
c2.add(Calendar.DAY_OF_WEEK, -w2 + 1);
//end Saturday to start Saturday
long days = (c2.getTimeInMillis()-c1.getTimeInMillis())/(1000*60*60*24);
long daysWithoutSunday = days-(days*2/7);
if (w1 == Calendar.SUNDAY) {
w1 = Calendar.MONDAY;
if (w2 == Calendar.SUNDAY) {
w2 = Calendar.MONDAY;
return daysWithoutSunday-w1+w2;
if (issue.get("customfield_11618")==null || issue.get("customfield_11616")==null )
return null;
return days(issue.get("customfield_11616"), issue.get("customfield_11618"))

This widget could not be displayed.


try this for your days function - the function you use calculates intentionally without weekend.

Calendar c1 = GregorianCalendar.getInstance();
		Calendar c2 = GregorianCalendar.getInstance();
		long days = (c2.getTimeInMillis() - c1.getTimeInMillis()) / (1000 * 60 * 60 * 24);
		return days;
