When considering the field of events, an important initial step is to consider the definition of an event. The goal of this article was twofold, first to take a novel approach in defining an event by considering the contextual aspects of an event from the traditional definitions, but adding the perspective of the attendee; and second to develop a typology focused on a unified definition of the field of events relational to the extant literature. The definition of an event is an occurrence that has a time element, two or more participants, is planned, and is a unique opportunity. A systematic review of extant literature was conducted in order to define the field of events. A total of 95 articles were analyzed. The field of events is characterized as having four major categories: professional, entertainment, social, and common cause. Within these four categories there are 20 types of events, all of which meet the four components of the definition of an event.
