Cron Ghost

Cron Ghost does one job - automatically unpublishes content at a time you choose.

Other modules to consider

If you'd like to publish and unpublish content on a schedule, consider these other modules:

Scheduler

Scheduled Transitions

Post-Installation

Choose which content types will use Cron Ghost via Configuration -> Content authoring -> Cron Ghost Settings, or by visiting /admin/config/cron-ghost on your site.

After enabling Cron Ghost for a content type, edit that content type's Form Display so the "Unpublish date and time" field is enabled and in the position you'd like it to be on the form.

Use

When creating or editing content, set the "Unpublish date and time" to the date and time you'd like the content to be automatically unpublished.

This functionality depends on cron being run at regular intervals.
