Commemoration ball

A Commemoration ball is a formal ball held by one of the colleges of the University of Oxford in the 9th week of Trinity Term, the week after the end of the last Full Term of the academic year, which is known as "Commemoration Week". Commemoration balls are held by different colleges each year, following a cycle by which each college holds a ball every three years.^[1]

Commemoration Week is so known because of the ceremonies in commemoration of the benefactors of the university that are held then, namely the Commemoration Day sermon formerly held (until 2006) on the Sunday, and the Encaenia ceremony (where the annual Creweian Oration in honour of benefactors is given) and garden party on the Wednesday of that week. Commemoration Week was formerly one of two occasions when balls were traditionally held, the other being Eights Week, the 5th week of Trinity term when the Summer Eights rowing races occur. Eights balls are nowadays comparatively rare.
