In WordPress you have the ability to schedule posts for the future, but you can also backdate them as well. The backdate feature is very handy if you are starting a new blog and adding a lot of content at once. You can backdate the posts so that they don’t appear to all be published on the same day.
Below are 3 tutorials – one using the classic editor (WordPress 4.9 and under), another using the latest version of WordPress with the Gutenberg editor (WordPress 5.0 and higher), and one changing the date from the posts menu page.
