This plugin allows a user to display the current date to the user via a shortcode in any place that a shortcode is usable.
Styling of the date will be the result of styling the shortcode itself. For example if the shortcode is written in bold, blue text, 
then the date will show up as bold, blue text
The formatting of the date is accomplished by changing the date format in the WordPress Admin Dashboard under Settings->General. Future 
releases of this plugin will allow formatting via the shortcode.

Display The Current Date In A Customizable Format

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:
<ul>
<li>Title</li>
<li>Message to display if no posts are found</li>
<li>Maximum posts to display</li>
<li>Show featured images (if available)</li>
<li>Category filtering</li>
<li>Optional On This Day archive page (new in version 2.0)</li>
</ul>
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.
