May Week is the name used in the University of Cambridge to refer to a period at the end of the academic year. Originally May Week took place in the week during May before year-end exams began. Nowadays, May Week takes place in June after exams, and is a cause for great celebration amongst the students of the University. Highlights of the week include bumps races, May Balls, June Events and garden parties.

A May Ball is a ball at the end of the academic year that takes place at any of the colleges of the University of Cambridge. They are elaborate and lavish formal affairs, requiring black tie or sometimes white tie, with ticket prices ranging from around £100 to as much as £640 for a pair of dining tickets at Trinity. May Ball budgets can exceed £200,000; a report by the student newspaper Varsity in 2016 found that the budget for the 2015 Trinity ball was £286,000. The balls are held in the colleges, starting around from 6-9 p.m. and lasting until well after dawn. "Survivors photographs" are taken of those who last until morning. Other colleges frequently hold winter balls, such as the popular Selwyn Snowball, who recently had acts such Tinchy Stryder and Mumford and Sons headlining.
