Jira "End date" field is not available?

[Test-user]

Hello,

I would like to list a start and end date field on my issues, to use it for BigPicture.

I managed to get Start Date to display on my issues (by going to Jira Settings > Custom Fields, search the Start Date field and assign it to each screen).

However, there is no End Date field in the Custom Fields section. It is just not there. 

I have recently trialed another, new Atlassian URL, where this End Date field actually WAS available. Of course I can manually it here, but I don't know if it is the same (I think it is a system field).

Start date and end date are not system fields, you will need to add them to your system yourself, and configure them to suit your usage.
