The Queen’s birthday is officially celebrated every year on a Saturday in June with a ceremony called Trooping the Colour. Though it is not her actual birthdate, the tradition is to hold the ceremony on a day in the summer when the weather is better and the public can enjoy the festivities.
This time-honoured tradition dates back to the early 18th century and involves hundreds of fully trained troops and horses, gathered together to present themselves and be inspected by the Queen herself. There is also a parade and carriage procession which follows down the Mall, ending at Buckingham Palace where the Queen takes the Royal salute.
Afterwards, the Royal family gathers on the balcony to watch a fly-past by the Royal Air Force. Unless you were lucky enough to receive a ticket in March, viewers can watch the procession from along the Mall.
The troops will also be rehearsing the ceremony two weeks prior, on June 2 in Horse Guards Parade, so you can go have a look before the official event!
