HOWTO: Show a post for only 5 days

OK,
I am relatively new to WordPress but If I were you I would think that cronjob/crontab is one way to do this.
There is a crontab plugin http://www.skippy.net/blog/category/wordpress/plugins/wp-cron/
Also here is a link to timestamp plugin
http://wp-plugins.net/plugin/set-postdate/

get the timestamp check it using crontab and if it matches your criteria delete/hide that post. (There could be a plugin for hiding posts )
If you know PHP you would probably know what I am getting at.

I haven’t checked WP APIs yet and have no idea how it is coded. A developer could probably hint and suggest what to do.

P.S. I could be totally wrong though 🙁
