Why does the Queen have two birthdays?

The Queen will celebrate her actual birthday this week when she turns 96 on Thursday.

The monarch, born on 21 April, 1926, did not join other royals at the Easter Sunday church service at Windsor Castle this weekend due to mobility issues.

Although concerns over the Queen's health remain - she also recovered from COVID as recently as February - she was visited last week by her grandson, the Duke of Sussex, ahead of his trip to the Netherlands with the Duchess of Sussex to launch the 2022 Invictus Games.

The surprise visit comes amid a difficult year for the Queen already in 2022, where she attended the memorial for her late husband the Duke of Edinburgh last month, and her gradual stepping back from performing as many royal duties.

Her actual birthday this week is one of two marked each year, with the monarch's 'official' birthday held in June.

When is the Queen's real birthday?

Elizabeth II was born on 21 April 1926, the oldest daughter of the Duke and Duchess of York, who became King George VI and Queen Elizabeth when her uncle abdicated the throne.

In 2020 and 2021 the Queen has been in Windsor for her birthday. She is often in Windsor at this time of year for Easter Court but in the two years of coronavirus restrictions, there have been fewer official elements of this period in the royal calendar.

She reportedly spent her 94th birthday in 2020 video calling her family members. Her 95th birthday was spent in mourning, as it came just four days after the funeral of Prince Philip.

Her birthday has been marked privately for several years, and 2021 saw no official confirmation of any activities. It was reported she had a quiet lunch with family.

One of the biggest parts of the Queen’s birthday celebration is usually a series of gun salutes in three places.

In London, a 41 gun salute is performed in Hyde Park, and a 62 gun salute at the Tower of London.

Closer to her Berkshire home, a 21 gun salute is normally held at Windsor Great Park.

A basic gun salute is 21 guns, and 20 are added if the salute takes place in a royal park, which is why it’s 41 guns in Hyde Park.

They are traditionally fired at 10 second intervals by the King’s Troop Royal Horse Artillery, a mounted ceremonial battery.

The Queen also gets gun salutes for her official birthday and her coronation day. They’re also fired for various events like royal births or for heads of state visiting.

There were no gun salutes in 2020 or the first part of 2021 due to the pandemic. They were reinstated after the death of Prince Philip on 9 April, but there were none for the Queen's real birthday.

The monarch's official birthday

The practice of an official birthday for the monarch dates back 260 years, when George II repurposed the traditional Trooping the Colour for his own celebration.

George II’s actual birthday was in November, and the monarch was fed up with terrible British weather putting a dampener on any plans.

So he decided to combine his birthday with the Trooping the Colour, a military procession which was held every year and already a fixture of the British calendar.

Queen Elizabeth II’s father, King George VI, had his official birthday on the second Thursday in June, and the Queen adopted this for a few years after she acceded.

But in 1959, she decided to change it to the second Saturday in June.

It just so happens that her official birthday isn’t too far away from her coronation day, but the two aren’t linked.

What is Trooping the Colour?

Trooping the Colour involves more than 1,400 parading soldiers, 200 horses and 400 musicians, who perform with military precision.

The parade moves between Buckingham Palace, The Mall and Horseguards’ Parade.

It’s also the time of year we get the famous balcony pictures as all the Royal Family waves to the crowds and watches the RAF flypast, which marks the end of the event.

The Queen used to ride on horseback with the parade to carry out the inspection but now arrives by carriage.

She is greeted by a royal salute and carries out an inspection of the troops, operational soldiers wearing their ceremonial uniform of red tunics and bearskin hats.

After the bands have performed, the Regimental Colour, or flag, is processed, or trooped, down the line of soldiers.

The Household Division’s website explains: “Regimental flags of the British Army were historically described as ‘Colours’ because they displayed the uniform Colours and insignia worn by the soldiers of different units.

“If Troops were to know what their Regiment’s Colours looked like, it was necessary to display them regularly.

“The way in which this was done was for young officers to march in between the ranks of troops formed up in lines with the Colours held high.

“This is the origin of the word ‘trooping’.”

In 2020 and 2021, the ceremony has been downsized to match the coronavirus restrictions in place.

In 2020, the Queen viewed a small ceremony at the Quadrangle of Windsor Castle. She did not have any family members with her, just a couple of her aides.

Soldiers from the Welsh Guards and musicians from the Massed Band of the Household Division marched from the parade area, outside the Chapel, to the quadrangle.

While the parade was meticulously planned to ensure there were no places for the public to gather and watch, castle staff could be spotted peering out of windows to watch.
