In the beginning was the Event module. It was the de facto standard for managing calendar types of data. That was before CCK. Content Construction Kit saw fit to bring about many changes in the world of Drupal.
With the rise of Views module, a new era was born. Shortly after, the super talented developer KarenS created Date module and Views and Date got together. Their offspring was the Drupal Calendar module.
And from that time on, a Drupal calendar was easily possible with date and time harmony spreading across the land.
