Change global project start and end date

Question

Hi,

I'd like to know how to change the start date of my project (01/09/25) and the end date (31/08/2028). Actually, in the chronology tab, in the graph part, My start date is october 24, end the end date is october 27 whereas some task are already configure after october 27.

I think we can configure this in the area global settings, but impossible for me to see this parameters.

Thanks for your help.

Dear @Cynthia Borot

Yes, in the Free plan, Jira only gives access to:

The basic Timeline (or Roadmap) feature, which is auto-calculated from issue Start and Due dates.

You cannot configure global project dates or modify the visible date range manually.

You also don’t have access to Advanced Roadmaps, where date field mapping and plan range customization are available.

So even though you’ve added issues into 2028, the project’s top-level display (e.g., the “October–December ’27” you’re seeing in your screenshot) will not automatically extend beyond what Jira thinks is the current latest visible timeframe — and you can’t change that in the Free tier.

You can check the differences in the following comparison:

Thanks for your reply.

Indeed when I changed task or epic issue date, it don't change the global project end date on the roadmap. I've plan epics and child tasks on 2028.

I've subscribe to the free plan. Perhaps it's one of its limitations ?

Hi @Cynthia Borot

Welcome to the Atlassian Community!

The project start and end dates in Jira’s timeline are automatically based on the earliest and latest issue dates.To adjust them, edit the Start date and Due date of your highest-level issues (Epics or Initiatives).If you’re using Advanced Roadmaps, you can also configure which date fields are used under Plan → Configure → Scheduling → Dates.Jira Cloud doesn’t allow manually setting project-wide start/end dates — they’re derived from issue data.
