In the United Kingdom, Trooping the Colour is also known as the Queen's Birthday Parade. It has marked the official birthday of the sovereign since 1748, and has occurred annually since 1820 (except in bad weather, periods of mourning and other exceptional circumstances). From the reign of King Edward VII, the sovereign has taken the salute in person. It was Edward VII who moved Trooping the Colour to its June date, because of the vagaries of British weather (his actual birthday being in November). From 1979 to 2017 it was always held on the Saturday falling between 11 and 17 June; however, in 2018 it was held on 9 June and in 2019 on 8 June.
