History and traditions of Harvard commencements

What was originally called Harvard Colledge (around which Harvard University eventually grew) held its first Commence­ment in September 1642, when nine degrees were conferred. Today some 1700 under­grad­uate degrees, and 5000 advanced degrees from the university's various graduate and professional schools, are conferred each Commence­ment Day.
