The ability to schedule posts is another great WordPress feature. It’s a very simple feature to use, yet many WordPress bloggers are not aware of it. They will enter 2 or 3 posts, and then publish them all at once or save them as drafts and come back and publish them later. Let WordPress do this for you!
How To Schedule A Post
Step 1 – look at your publish options box. Click edit.
Step 2 – enter the date and time you want your post to publish. Click OK
Step 3 – Click Schedule. Your post is now scheduled to publish on the day and time you selected.
No problem! Just click edit again.
Enter the new date and time and click OK.
You can also do this step using Quick Edit
Surf to Dashboard / All Posts
Hover over the post you want to re-schedule and click Quick Edit
Change the date and click Update.
