Publish Dates and Hiding Web Pages
There are options in the Page Settings when editing page content that allow you to control the visibility of your webpages.
Publish Date is a webpage management setting used to control if content is visible to search engines and users. You can change the publish date of any website content on the right hand side of the content editing page underneath Page Settings. Click the publish date text box and select a date and time you want it available to the public for. When that date hits, your page will automatically show in navigation and on every web page that would link to it automatically.
Show in Site Navigation
Show site in navigation is can be found in the content area when editing a page under the page setting area. Visible means the page will be shown in navigation and section links. No Visible means it will not be shown in navigation and section links. The page can still be accessed directly.
