Bloggers often want to know if it is possible to backdate a blog post. The short answer is yes, but there are a few caveats to keep in mind.
First, it’s important to remember that the date of a blog post is determined by the time it was originally published, not when it was last edited. So if you make any changes to a post after it’s been published, the date will update accordingly.
Second, if you want to backdate a blog post to a specific date, you’ll first have to remove any existing comments or other updates that may have been made since that date. If you don’t do this, your post will appear as if it was published on the current date (which may not be what you want).
Finally, backdating a blog post won’t always work. If someone has already linked to or quoted your post on another website before the new date you’ve chosen comes around, your post will appear as if it’s newly published on the original date instead of the corrected one.
In these cases, you’ll probably want to either revise the content of your post or find another way to promote it.
