Calculate working days between 2 dates

Question

Hi Guys,

Im trying to calculate 2 working days in postfunction but im having a abit of trouble, here is the code i currently have:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue 
import com.atlassian.jira.issue.CustomFieldManager
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()

MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject('OE-2250')

Date test = issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(10804)); //09-Jan-17
Date test2 = issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(11504)); //16-Jan-17

startCal = Calendar.getInstance();
endCal = Calendar.getInstance();
startCal.setTime(test);   
endCal.setTime(test2);   
int numberOfDays = 0;
while (startCal.before(endCal)) {
            if ((Calendar.SATURDAY != startCal.get(Calendar.DAY_OF_WEEK))&&(Calendar.SUNDAY != startCal.get(Calendar.DAY_OF_WEEK))) {
                numberOfDays++;
                startCal.add(Calendar.DATE,1);
            }else {
                startCal.add(Calendar.DATE,1);
            }
        }
		return numberOfDays

Thank you so much

Try this one:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.CustomFieldManager
MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject('OE-2264')
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
Calendar startCal = Calendar.getInstance();
Calendar endCal = Calendar.getInstance();
startCal.setTime(issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(10804)));    //14-Jan-17
endCal.setTime(issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(11504)));      //18-Jan-17
int numberOfDays = 0;
while (startCal.before(endCal)) {
        startCal.add(Calendar.DAY_OF_YEAR, 1);
        if (    (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) 
             || (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY)) {
                continue;
        }
        numberOfDays++;
}
return numberOfDays

Thank you so much again Vasiliy, definielty does work, but its looks like its calculating Sunday into the logic:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.CustomFieldManager
MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject('OE-2264')
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
Calendar startCal = Calendar.getInstance();
Calendar endCal = Calendar.getInstance();
startCal.setTime(issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(10804)));    //14-Jan-17
endCal.setTime(issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(11504)));      //18-Jan-17
int numberOfDays = 0;
while (startCal.before(endCal)) {
        startCal.add(Calendar.DAY_OF_YEAR, 1);
        if ((startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) && (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY)) {
                numberOfDays++;
        }
}
return numberOfDays

Is returning 4

Any idea why this is happening?

Cheers,

Pon

Try this refactored code:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.CustomFieldManager

MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject('OE-2250')
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
Calendar startCal = Calendar.getInstance();
Calendar endCal = Calendar.getInstance();

startCal.setTime(issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(10804)));    //09-Jan-17
endCal.setTime(issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(11504)));      //16-Jan-17
int numberOfDays = 0;

while (startCal.before(teendCalst2)) {
        startCal.add(Calendar.DAY_OF_YEAR, 1);
        if (    (Calendar.SATURDAY != startCal.get(Calendar.DAY_OF_WEEK))
              &&(Calendar.SUNDAY != startCal.get(Calendar.DAY_OF_WEEK))) {
                numberOfDays++;
        }
}

return numberOfDays;
