Calendar Content

Can I stop events from requiring the default "event_start" and "event_end dates by overriding them with my own created datestamps?

I installed the Calendar module on my site (drupal 5) and when I go to create a new content type with a datestamp that I created specifically for this calendar it automatically puts another date input "event_start" and "event_end" There are also title, taxonomy, and body, they are all unchangeable. I want to use MY datestamp for the calendar, but since the auto-generated one is required and I cannot edit it I have to put in two dates, and therefore two events on my calendar every time I make an event.

I am new to Drupal so thanks for any help.
