An occasion can be defined as a specific time and place where a public speaking situation occurs. Public speaking occasions can be affected by events that have very recently occurred (e.g., the morning's news may be fresh in your audience's mind), by the time of day (8:00 A.M. lectures are different than 10:00 A.M.), or by the general atmosphere at the venue (a convention center is typically more tranquil than a football stadium).
