You can schedule pages to automatically publish at any time in the future. If you want to remove an already published page and automatically republish it at a specific time/date in the future, the directions are the same.
In the Publish module to the right of the page editor, click Edit in blue next to Publish immediately.
Set the future date/time when you want the page to publish itself and click OK.
Instead of Publish immediately, it will now say Schedule for: followed by the date and time you specified, and the button has changed from Publish to Schedule.
