Birthday Honours is, in some Commonwealth realms, the marking of the reigning monarch's official birthday by granting various individuals appointment into national or dynastic orders or the award of decorations and medals. The honours are presented by the reigning monarch—currently Queen Elizabeth II—or one of her viceregal representatives. It is generally one of two times per year that these honours are bestowed, the other being the New Year Honours.
Known as Queen's Birthday Honours (or King's Birthday Honours in times of a male monarch), all royal honours are published in the relevant gazette. The lists are also published in the daily newspapers of each realm.
Honours have been awarded on the sovereign's birthday since at least 1885, during the reign of Queen Victoria. The birthday of her successor, King Edward VII (r. 1901–1910), fell on 9 November 1901. After 1908, the monarch's official birthday in the United Kingdom was moved to the first, second, or third Saturday in June. Other Commonwealth realms celebrate the official birthday on different dates (generally late May or early June), and release their honours lists accordingly.
