Freelock Blog: Change the display of an event after it happens

Event Calendars seem to be very common on the Drupal sites we build. One of the best ways of improving engagement on a site is to add content about the event after it happens. People who attended an event might come back for a recap, or to see pictures or notes from other participants, while people who did not attend can get a sense of what a future event might be like based on your past events.
