A powerful yet simple plugin for adding calendar functionality to posts. Great for using posts as events and calendar inputs.

Adds a ‘calendar-box’ to the edit post mode. Here you set up to 10 different dates for your post to be associated with. Through a sidebar widget you control how to display posts that have upcoming dates set to them. This plugin should work fine with other post plugins and the posts you add “calendar-post-dates” will still be displayed in your normal blog post flow.
