This screencast demonstrates how to install and configure the new 7.3 version of the Calendar module for Drupal.

Calendar 7.3 is a complete rewrite of the calendar module resulting a substantial reduction in code size (from 500+k to 70k)!
Calendar 7.3 uses a custom date pager instead of the attached navigation displays in previous versions. This drastically reduces the amount of custom code, should make calendar much easier to use and customize for panels & blocks, as well as making it easier and faster to maintain.

Thanks Karen!
