Facebook allows you to create posts for your Facebook page and schedule them to be published at some date/time in the future. This can be really convenient if you want the post to appear when you will be doing other things, you have events coming up, or just want to get ahead of the game. The process is easy.
Step 1: Start building your post as you would normally
Step 2. Schedule your post
Step 3: You can view, change, or delete your scheduled posts from your Activity Log. A link to the Activity Log will be provided when you schedule your post & a link is at the top of the Admin Panel on your Facebook page.
Please note, you can only schedule posts on Facebook pages. This does not work for personal Facebook accounts.
