Calculated Date Field - Difference between two Dates


i use Misc Custom Fields and i want to calculate the Difference between 2 Dates in days.

Date 1 is Customfield 13478, Date 2 is Customfield 13471.

I create an Customfield this these describtion:

<!-- @@Formula: (issue.get("customfield_13471") != null? issue.get("customfield_13471") : 0)
- (issue.get("customfield_13478") != null? issue.get("customfield_13478") : 0) -->

and Type "Calculated Date/Time Field"

and an other with Type "Calculated Nunber Field"

Both Fields are available on the issuescreen. Tested by "Where is my sreen". But i didnt see one of these calculated with the days (Customfield_13471)-(Customfield_13478).

Desired Result an these Example:


Thanks for your help!

Best regards

you may try below one:


<!-- @@Formula: issue.get("customfield_13471")==null ? null : (issue.get("customfield_13471").getTime() - issue.get("customfield_13478").getTime()) / 1000 / 3600 / 24 -->

Hi Stephan

Are you using jira cloud or jira server . Did you find any solutions for this. I am trying to solve a similar issue.

First, you need to create the 2 date fields you want to play with.

To get the custom field ID, go to your custom field administration and place your mouse on the "edit" button (don't click). On the bottom left corner of your screen you will see the field ID.

To create the calculated field, you need to create a new custom field of the type : calculated number field

In the description you add (please replace the ID by yours):

<!-- @@Formula:
if (issue.get("customfield_13471")==null || issue.get("customfield_13478") == null)
return null;
return (issue.get("customfield_13471").getTime() - issue.get("customfield_13478").getTime())/ 1000 / 3600 / 24; -->

If one of the date fields you used is null, the calculated field will return null so it won't appear on your screen.

Hope it helps
