Milestones on your Facebook page.
Milestones are certain important events that can be used by an admin to highlight these events on their Facebook page. When a milestone is set, a photo is automatically expanded to widescreen when it is displayed on the timeline of the given page. To type a milestone, click on the “Milestone” option on the sharing tool at the top of the page. A headline, location, date and details can also be added to any milestone in order to describe it in a better way.
