You can schedule pages to automatically publish themselves 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.
Scheduling a Page
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.
Click Schedule. At the exact date/time you set, your page will automatically be published for visitors to see.
