Content Expiration is a WordPress plugin that allows authors/editors to set an expiration date on posts or pages. The plugin is intended to be simple with easy-to-read code.
An expiration can be set by specifying a number of days (e.g., expire in 90 days) or a specific date/time (e.g., May 10, 2018 at 10:00 PM). Two weeks prior to the expiration date, the author of the post/page is sent a warning email. The author receives another notification email upon expiration.
When a post/page expires, it is not deleted. Instead, it is given a status of Expired and hidden from public view. Visitors to the site will receive the regular WordPress 404 Page Not Found error.
The expiration can be reset by any editor or administrator of the site. They must log in and edit the expiration settings of the post/page.

This plug-in adds a meta box to the post and page writing pages in wp-admin to set up an expiration date for that item. It uses the WordPress cron feature to be executed once a day.
After the expiration date the post will be in the trash can of WordPress. The plug-in does not delete any post, but WordPress will depending on the trash can settings.
