The first official birthday of Elizabeth II, daughter of George VI, was the last to be celebrated in June; the haphazard format was abandoned in 1952, when the Governor General-in-Council moved Empire Day and an amendment to the law moved Victoria Day both to the Monday before 25 May, and the monarch's official birthday in Canada was by regular viceregal proclamations made to fall on this same date every year between 1953 and 1957, when the link was made permanent. The two holidays are in law entirely distinct except for being appointed to be observed on the same day; it is a general holiday in Nunavut and New Brunswick (there prescribed as a day of rest on which retail businesses must be closed). The Queen's official birthday is marked by the firing of an artillery salute in the national and provincial capitals and the flying of the Royal Union Flag on buildings belonging to the federal Crown, if there is a second flag pole available.
