Pages can be published immediately or at a specified time. When the "Publish" button is clicked, the option to “Publish Later” can be selected. Choose the date/time to publish, enter an optional comment, and click “Schedule.”
The Composer toolbar will now indicate the scheduled date/time for publishing the page.
The status icon will be blue to indicate that the page is scheduled to be published, and the Publish button has an option to update the schedule.
Use the "-" icon in the date/time field to clear the publish schedule and revert the page to Draft status.
Note: Admins without rights to publish will still get the same scheduling option when requesting to publish the page.
