Use case

This calculated field will display the difference between two dates reflected in Date picker fields in business days.


Set up a calendar
Add a new calendar in Jira administration > Manage apps > Calendars

Name the calendar with a recognizable name as in the following example.

Business Hours

Introduce a relevant expression in the Specification field like the following one:



Create a new Calculated Text Field (by JWT) custom field and name it properly.

Providing a description will help you to identify what the custom field does but this step is optional

Parser expression

Add the following parser expression:

formatWorkDuration(timeDifference({issue.cfaaaaa},{issue.cfbbbbb},"Business Hours",LOCAL))
Do not forget to replace {issue.cfaaaaa} and {issue.cfbbbbb} with the field codes of the appropriate custom fields.

Add the field to the relevant view screens.

Remember: All calculated fields are read-only and cannot be manually updated on a create or edit screen.
