Date Range Filter is a free WordPress plugin designed to improve the functionality of the default date filter in the WordPress admin interface. This plugin allows users to filter posts by a custom date range or select from predefined ranges, streamlining the process of managing content based on publication dates. It is particularly useful for users looking to organize and locate posts more efficiently based on specific time frames.

The plugin requires PHP version 5.3 or higher, with 5.4 strongly recommended for optimal performance. By default, it filters posts based on their creation date, but users can easily modify the filter to sort by post modified dates through a simple function. This flexibility makes it a valuable tool for anyone looking to enhance their WordPress productivity.
