The King will celebrate his first birthday as monarch tomorrow and is expected to mark the occasion privately after an eventful start to his reign.
Charles became king after the death of the Queen on September 8 and has since had a busy period.
As Prince of Wales, he was sometimes away on official foreign tours during his birthday and would celebrate it overseas with a cake.
Charles spent the day ahead of his 74th birthday leading the nation in honouring its war dead during the annual Remembrance Sunday service at the Cenotaph.
His floral tribute to the fallen left at the memorial in Whitehall featured the words ‘In memory of the glorious dead. Charles R’.

The King’s milestone will be marked by the Band of the Household Cavalry performing Happy Birthday during the Changing of the Guard ceremony at Buckingham Palace on Monday.
Gun salutes will be fired across the capital in honour of his birthday for the first time, with the King’s Troop Royal Horse Artillery firing 41 volleys from midday at London’s Green Park, and immediately afterwards the Band of the Scots Guards will perform Happy Birthday in the park.
The King’s Troop is a mounted ceremonial unit in the British Army that fires salutes on royal anniversaries and major events like state visits, and provides a gun carriage and a team of black horses for state and military funerals.
An hour after the Troop, the Honourable Artillery Company will fire a 62-gun salute at the Tower of London.
The Army’s oldest regiment has a demanding operational reconnaissance role in addition to its ceremonial responsibilities.
Big Ben chimed eleven times at 11am, as it returns to service after years of maintenance and repair.
As Charles leads the nation at the Cenotaph for the first time as King, the service is a poignant moment for the royal family. On Friday, the late Queen and her commitment to war veterans was remembered in an evening attended by members of the royal family including the Prince and Princess of Wales and Princess Anne.
Today’s service also marks the 40th anniversary of the war in the Falklands, in which 255 British personnel lost their lives. Similar services were held across the country, including at the National Memorial Arboretum in Staffordshire.

Crowds lined the streets of London, with war veterans including Chelsea Pensioners preparing to take part in the march.
At around 10:40am, the march past the Cenotaph paused temporarily while Scottish members of the UK’s armed forces, the Fourth Battalion of Highlanders, played the bagpipes, accompanied by drums.
At 10.58am, the military parade was brought to attention as King Charles III arrived.
Big Ben rang eleven times to mark the beginning of the two minutes of silence, and a somber hush fell over the crowd.
After the two minutes of prayer and reflection had ended, in an emotional tribute to those killed during the wars of the last century, members of the military played the Last Post.
King Charles III then laid his wreath and saluted to the Cenotaph on behalf of the nation. A wreath was then laid on behalf of Her Majesty the Queen Consort.
The Queen Consort’s assistant equerry, Captain Edward Andersen, laid her tribute, the first laid on behalf of Camilla alone.
The Prince of Wales then proceeded to lay his wreath, complete with the feathers of the heir apparent. This was the wreath previously laid by his father. The wreath, bearing the colours of the Prince of Wales, also bears a brand-new ribbon in Welsh red.

Big Ben strikes back!
Big Ben struck 11 bells at 11am
Big Ben was struck 11 times at 11am to mark the start of the two-minute silence on Remembrance Sunday.
Over the past five years the Elizabeth Tower, and the clockwork and bell mechanism within it, have undergone the biggest repair and conservation project in its 160-year history.
The tower, at the northern end of the Houses of Parliament, which is also known as Big Ben after the bell inside, had been covered in scaffolding during the restoration work but that has now been removed.
The two-minute silence marked the official return of the Elizabeth Tower’s bells after they were silenced at the beginning of the conservation programme in 2017.
Big Ben joined bells across the country and worldwide to commemorate those who lost their lives in the two world wars and later conflicts.
The Earl of Wessex and Princess Royal then laid a wreath, before one was laid on behalf of the Duke of Kent.
The military parade then stood at ease as music played and Prime Minister Rishi Sunak and Sir Keir Starmer led the rest of the wreath-laying. They were followed by leader of the SNP Ian Blackford and leader of the Lib Dems Ed Davey, and military representatives.
A short service including a hymn and the Lord’s Prayer was then led by the Lord Bishop of London, Dame Sarah Elisabeth Mullally. She has held the role since 2018.
The 10,000 veterans then began filing past the memorial after the final wreaths had been laid by those affected by military losses.
PM Rishi Sunak shared a video paying his respects to war veterans on Twitter, adding: ‘On this day and every day, we will remember them.’
Sir Keir Starmer said: We will never forget those who made the ultimate sacrifice to keep us safe. We will remember them.’
The day was marked around the UK, with services also taking place at the National Memorial Arboretum in Staffordshire and the WW1 Memorial in Portsmouth, and other local memorials in all four nations.
Defence Secretary Ben Wallace, speaking to broadcasters in Westminster, said: ‘Today is a reminder that we’ve suffered wars in Europe before and tens of thousands of British service personnel gave their lives as a civilian to defeat fascism.
‘Here we are again, tragically, decades later with a war on continental Europe in Ukraine, where a similar Russian regime is trying to impose its will on a sovereign state, costing tens of thousands of lives.
‘And, of course, what remembrance is about is recognising that freedom isn’t free – people make sacrifices and this nation made the ultimate sacrifice on two occasions in the great wars, but also (in) other conflicts, and remembrance is a time to reflect on that.’
Speaking about the King, Mr Wallace said: ‘I think he will obviously remember his mother, the late Queen Elizabeth II, because … for him, he’s been standing at this cenotaph for many, many years alongside her and, obviously, he is now the new monarch of this country.
‘I think he’ll reflect that she gave her service to the very end, she never stopped being the sovereign, she didn’t abdicate and all these other things that people used to speculate on. She was married to this country and her duty.’

The Remembrance Sunday ceremony has added poignancy this year as it is the 40th anniversary of the Falklands War, with former veterans marching past the Cenotaph.
Retired Brigadier Jon Mullin, who served as a Lieutenant in the 9 Parachute Squadron Royal Engineers during the conflict, is marching with South Atlantic Medal Association 82.
Reflecting on the sacrifices made to liberate the Falklands, he said: ‘I wanted to be part of a national commemoration to commemorate all those people who did this wonderful feat of arms and put it all together, and many have passed on in the intervening years’I think it’s important that the nation doesn’t forget the sacrifices.’
