Scheduled publishing

You can schedule content to be published at a certain time. 

If you are working with shared blocks, remember to publish those beforehand or also schedule them. If you publish them beforehand, they are not visible until the page they are in, is published. If you are working with inline blocks, you only need to schedule the page. 

Choose Schedule to Publish under Publish.

Choose the date and time you want the content to be published and push Schedule. 
Remember to check the timezone and adjust the time accordingly.
