The birthday of the Queen Consort is observed in the United Kingdom every July 17, commemorating Queen Camilla's birth on July 17, 1947. This day is recognized as an official Union Flag flying day, during which the Union Flag must be displayed on all government buildings. Local authorities and organizations are encouraged, though not required, to fly flags in celebration. Queen Camilla has served as the Queen Consort since September 8, 2022, following the ascension of her husband, King Charles III. The celebration of her birthday is part of designated flag flying days in the UK, alongside other royal occasions such as the King’s official birthday and the birthday of the Prince of Wales.
