This is a question that comes up frequently, and there is no definitive answer. In general, it’s generally not possible to backdate blog posts.
This is because blog posts are typically created on a “live” platform, which means that the content is updated as new information is added. As a result, it’s often difficult to determine when a specific piece of content was originally published.
There are a few exceptions to this rule. For example, if you’re quoting other people’s blog posts in your own content, you may be able to backdate those quotes.
Additionally, if you’re using a third-party blogging platform like WordPress or Tumblr, it may be possible to backdate your posts using their built-in timestamping features. However, these are rare cases and should not be relied upon as reliable methods of backdating content.
Ultimately, the best way to determine the date of a particular blog post is to consult the original source material. This can be difficult if the post has been deleted or archived online, but it’s always worth trying to track down the original source material in order to confirm the date of a post.
