The monarch's birthday has been celebrated in the United Kingdom since 1748, during the reign of King George II. Queen Elizabeth II's Official Birthday was originally celebrated on the second Thursday of June, the same day that her father, King George VI, celebrated his Official Birthday during his reign. However, this was changed in 1959, seven years after she became Queen, and her Official Birthday has since then been celebrated on the second Saturday of June. Edward VII, who reigned from 1901 to 1910 and whose birthday was on 9 November, after 1908 moved the ceremony to summer in the hope of good weather.
