How to open Project TimeLine
Open a Jira project and select the TimeLine option in the project sidebar (left side).
All Releases/Epics will be represented in the visible area and a vertical dotted line will show today’s date. Usually, the period you see on the screen is about one and a half years, but it really depends on your screen resolution.
Left-click your mouse and move left and right: that is how you move on your TimeLine.
