dhtmlx

An easy to implement event calendar plugin built on top of <a href="http://dhtmlx.com/docs/products/dhtmlxScheduler/" rel="nofollow ugc">dhtmlxScheduler</a> 
that provides an Ajax-based scheduling interface similar to Google Calendar. The plugin allows you 
to manage single or multiple user events, display any type of events and appointments, and put a list of the upcoming events on a side bar.
Users can add/edit/delete events on the fly and easily change event date and time by simply dragging the event boxes. 
You can set up different levels of permissions to people who will use the calendar: make the scheduler read-only or allow 
a group of users to edit the events through a web-based calendar interface.
The calendar can be configured to display events in Day, Week, Month, Agenda, Timeline view, as well as in any custom view. The intuitive admin panel 
makes it easy to customize the calendar to your needs. You can use the plugin as an event calendar or as archive calendar to display your blog posts archive (in this case it works in read-only mode).
