title: Wordpress post to change category after 5 days automatically
body: <p>So essentially what I would like to know is if this is even possible. I use my wordpress site to promote free Kindle books, which are free for up to 5 days. </p>
  
  <p>At the moment I use Gravity Forms to automatically post the freebie posts but I still have to go in and 'archive' them once they are no longer free. This is a tedious task that I would pretty much do anything to automate. </p>
  
  <p>Now, I don't need the actual content of the post to change at all - just the post category to automatically change after 5 days. So, anything posted using that gravity form would automatically change to the 'books' category after 5 days. </p>
  
  <p>Is this possible? What kind of script would I use to make this happen? Would it be a Wordpress edit or a gravity forms edit? I most likely will have someone do it, and if you want to do it, feel free, but right now I am simply asking if it is even possible and to get a basic understanding of how to go about it.</p>
