Post Expire Date Sidebar for Gutenberg is a productivity-enhancing plugin designed for WordPress users. It allows users to set expiration dates and times for their posts, automatically changing the post status to draft, trash, or private once the set date is reached. This feature can be easily managed through a dedicated sidebar in the Gutenberg editor, making it simple to keep track of content that needs timely updates or removal.

The plugin utilizes wp-cron to schedule expiration events, ensuring that posts are updated accurately. Users can also modify or remove expiration dates as needed. Additionally, the plugin supports shortcodes, enabling the display of the expiration date and time directly within the post content using the shortcode [expiration_datetime]. This functionality is particularly useful for managing time-sensitive posts efficiently.
