This plugin automatically applies a full-site grayscale filter on user-specified dates, allowing site owners to respectfully observe memorial days. It is designed for administrators of sites built on popular content management systems who wish to implement this visual tribute without manual intervention each year.

• Automatic Date-Based Filtering: The plugin activates the grayscale effect automatically on pre-configured dates, removing the need for manual code changes each year.
• Customizable Date Settings: Administrators can define and modify the specific dates when the filter should be applied directly from the site's admin interface, using a simple comma-separated format.
• Simple Installation: It can be installed directly from the plugin directory within the admin area or via manual upload, with clear setup instructions provided.
• Cross-Platform CSS Code: For sites on other platforms, the repository includes the standard CSS code required to achieve the grayscale effect, which can be manually added to a site's header.

The tool handles the technical implementation, ensuring the visual change is applied site-wide and reverts automatically after the specified date passes.
