Is there a way to calculate the actual duration for an issue?

Jocelyn,

There are a few different ways to calculate this value using text mode. If you wanted to take into consideration all (calendar) days, rounded to 2 decimal places, you would use the following text mode code:

displayname=Issue Duration

valueformat=HTML

valueexpression=ROUND(DATEDIFF({actualCompletionDate},{entryDate}),2)

If you wanted to only take into considering weekdays, you would use the following text mode code:

displayname=Issue Duration

valueexpression=ROUND(WEEKDAYDIFF({entryDate},{actualCompletionDate}),2)

valueformat=HTML

Additional information regarding calculated data expressions can be found here: https://one.workfront.com/s/article/Calculated-data-expressions-679086747

Another option would be to create a calculated custom field on an Issue Custom Form so that you can group or chart by the Issue Duration value.

If you have any questions, let me know!
