This could help us in creating a project report: Project created x years ago and not used since last y years. When will we get project created time?

I've seen we can simply workaround this by using a global automation rule and set a project property for it.

Seems I was too hasty. It doesn't work that way. Unclear why, but automation rule throws errors when saving it.

Such a low hanging fruit... Audit logs unfortunately get deleted over time... so have that value available would be very useful.

It would seem like the Details page on the Project Settings (for Software projects) would be the obvious choice. Seems like a small UI change. 

If the project was created within the last 6 months, there should be entry in Jira Audit Log with 'Change Summary' of "Project created" with a timestamp. 

FYI - 

Since the create date isn't persisted, we wanted a way to capture that data.  As others have mentioned you can get older data from the audit logs and/or approximating by the oldest issue.
We implemented Automation solution on a go forward basis to store the data as a project property.  Of course you would need to fetch the property later, but it least it will be stored.

Automation details:

When:  Project created  (for All projects)

Send web request:  (your_domain)/rest/api/2/project/project.id/properties/projCreate

Put headers as needed, then

HTTP method:  PUT

Custom data:   {"CreateDt": "now.jiraDate"}

That will save it going forward.

Workaround

Hello Everyone,

I'm Leo from DEISER (Marketplace partner). 

Projectrak allows you to store the project's creation date. After you install Projectrak, the field Creation date is automatically filled in every time someone creates a project.

Projectrak has more features, discover it on the marketplace
