In the University of Cambridge, the first Tuesday in July is usually the Commencement Day. The Commencement Sunday is the Sunday immediately before the Commencement Day. It is a commemoration day.
On Commencement Sunday, the Vice-Chancellor invites to dinner all noblemen, the three Regius Professors, and their sons and the public orator.—Adam Wall, Ceremonies observed in the Senate House of the University of Cambridge, 1798, p. 76.
