April 21st marks one of the Queen’s birthdays.
The Queen traditionally has two birthdays, her actual birthday and an official birthday marked every summer by the Trooping the Colour ceremony.
This dates back to Edward VII, who was born on November 9 but celebrated the birthday in May and June as the weather was better during these months for outdoor events.
To celebrate turning 91, the Queen attended the Dubai Duty Free Spring Trials and Beer Festival at Newbury Racecourse.
And she looked like she had a lovely birthday.
Then an hour later the Honourable Artillery Company fired a 62-gun salute at the Tower of London – an extra 21 for the City of London.
And there was this – a regal rendition of Happy Birthday was played during the Changing the Guard ceremony in honour of the Queen’s 91st birthday.
