How to calculate due date based on original estimate and start date

[Tal Shahar]

Hi, I want to calculate 'due date' field based on 'start date' + 'original estimate', so for example if the start date is 1/9 and original estimate is 3d the due date should be automatically updated to 3/9. 

I have script-runner plugin installed if that's relevant.

Thanks

Hi @Tal Shahar 

We have recently published a kb article to add Orginal estimate to a date field using Automation for Jira. Hope this helps :)

PS! The one above did not update due date properly. This one does it: 

Did not consider business days initially, edited: {{now.plusBusinessDays(TimeTrackingDays.asNumber)}}
