Task: Question Answering
Input (English): Passage: Queen's Official Birthday -- The sovereign's birthday was first officially marked in the United Kingdom in 1748, for King George II. Since then, the date of the king or queen's birthday has been determined throughout the British Empire, and later the Commonwealth of Nations, either by royal proclamations issued by the sovereign or governor or by statute laws passed by the local parliament. The date of the celebration today varies as adopted by each country and is generally set around the end of May or start of June, to coincide with a higher probability of fine weather in the Northern Hemisphere for outdoor ceremonies, rather than with the monarch's actual birthday, that of the present monarch being 21 April. In some cases, it is an official public holiday, sometimes aligning with the celebration of other events. Most Commonwealth realms release a Queen's Birthday Honours list at this time.
