An event is something that happens, or might happen. In the event that you get stuck in traffic, the wedding will continue. It is too important an event to wait even for someone as important as you.

When something is eventful, many things happen during it. In a detective story, a protagonist can protect himself by mailing an envelope to the police to be opened "in the event of his death." In the novel White Noise, Don DeLillo describes an Airborne Toxic Event, both predicting and mocking the disasters of our time.
