Answer:
Special events that mark the transition from one role to another, such as graduation or a wedding ceremony are known as rites of passage.
Explanation:
A rite of passage is a ceremony that celebrates a person's growth or change in status. For instance, in your high school graduation ceremony, everyone present is there to acknowledge that you and your classmates are now leaving one group - high-schoolers - to enter another - university or college students, for example. Other examples of rites of passage are: bar/bat mitzvah, sweet sixteen parties, baptisms, weddings, funerals.
