On This Day (formerly « Room 34 presents On This Day ») is a simple widget that displays a list of blog posts that were published on the same date in previous years. Customization options include:
- Title
- Message to display if no posts are found
- Maximum posts to display
- Show featured images (if available)
- Category filtering
- Optional On This Day archive page (new in version 2.0)
Important: While not technically required, the On This Day archive page assumes your theme includes an archive.php file that uses the the_archive_title() function to display the page title.
