Updates publication dates so lists and feeds see newer timestamps. Each post, page, or product waits your chosen time after its publish date, then can auto-update. WP-Cron only checks for due items every so often (hourly / twice a day / daily), which is separate from “yearly per post.”
What gets republished
Only post-like content: Posts, Pages, Products (WooCommerce), and any other public post type registered by themes or plugins. Categories, tags, and other taxonomies are not separate targets—the plugin does not “republish” terms.
Highlights
<ul>
<li>Schedule — On/off and wait after publish date (hourly … yearly). New installs default to Quarter (Recommended) (~90 days).</li>
<li>Configure — Choose which public post types are included and how many items run per batch (Advanced).</li>
<li>Per item — On each post/page/product (etc.), override: follow site default for that type, force ON, or force OFF. Republish now for immediate date bump on published items.</li>
<li>Safe defaults — New custom post types appear in settings turned off until you enable them.</li>
</ul>
Important
<ul>
<li>Republishing sets published and last modified times to the republish moment. It does not rewrite body content.</li>
<li>Uses GMT publish time. Bumps may trail the due moment by up to one cron check.</li>
<li>WP-Cron needs traffic; use server cron + <code>wp-cron.php</code> for steady timing.</li>
</ul>
<h3>Privacy</h3>
<ul>
<li>Stores settings in the WordPress options table (<code>wapr_options</code>, <code>wapr_scheduler_sig</code>).</li>
<li>Stores per-post choice in post meta (<code>_wapr_republish</code>) when not using the default.</li>
<li>Does not send data to external services, analytics, or tracking endpoints.</li>
<li>Scheduled work runs via WordPress’s own WP-Cron on your server.</li>
</ul>

Bumps publish dates on a per-item timer you set (from each item’s publish time, GMT)—no duplicate posts.

** WARNING: DON’T USE THIS PLUGIN IF YOUR PERMALINKS INCLUDE DATES **
The Republish Old Posts plugin helps revive old posts by resetting the publish date to the current date. This will push old posts to your front page, the top of archive pages, and back into RSS feeds. Ideal for sites with a large repository of evergreen content.
Why would you want to do this? Here are a few reasons:
<ol>
<li>New visitors to your site haven’t seen your old content. This will help them discover it.</li>
<li>Old content won’t show up in date-based searches on search engines, but resetting the date can make them look fresh again.</li>
<li>People like to share and link to new content and they determine that by looking at the publication date.</li>
</ol>
A <a href="https://infolific.com/technology/software-worth-using/republish-old-posts-for-wordpress/#pro-version" rel="nofollow ugc">pro version</a> (a lifetime license is less than $15) with many additional options (see screenshots) for controlling when and what posts are republished.
