<P> 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 , according to either different 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 . </P>
