From project phases and product launches to releases and key dates, milestones are a great way to track whether your work is on schedule. Add a milestone section to the Timeline view, create milestones and plan tasks to meet them.

To enable milestones, click in the Timeline panel to the left.
To create a milestone, click on any day in the milestone section.

Viewing milestones in other views
In all other views, milestones will look pretty the same.
