This is a game changer. Until the release of this feature by facebook, the only way to schedule a post on Pages was through a third-party app but now Facebook has baked that feature into its system, you can post content for 6 months in advance.
By clicking on the little “clock” icon in the lower left corner of the status update box, you will open a “set time” feature. Once you schedule something into the future, the “Post” button becomes a “Schedule” button. You can schedule image shares and more.
