In the Unite States and Canada a prom, short for promenade, is used to describe a semi-formal (black tie) dance held at the end of an academic year. In the United Kingdom, the term is more widely understood to be in reference to a season of classical concerts or "proms", which have been held between July and September since 1895, today run by the BBC. The British synonym for the North American event would be Leavers' Ball, Leavers' Dinner or informally Leavers' Do, closer to the Australian description (see below.) In Canada the terms Grad or Formal are most common and the event is usually only held for those in their graduating year of high school or middle school.
