King Charles III is reportedly celebrating his first birthday as a British Monarch in private. He turned 74 years old on Monday.

Express UK said there had been no announcements with regard to any planned engagements for the royal’s special day. Accordingly, it is believed that he would mark his birthday privately.

The publication noted, however, that the Band of the Household Cavalry would mark the King’s birthday. As stated, they will perform “Happy Birthday” during the Changing of the Guard ceremony at Buckingham Palace.

The outlet continued in the report that the King’s Troop Royal Horse Artillery will fire 41 volleys at London’s Green Park at noon. It is added that the Band of the Scots Guards will provide a rendition of “Happy Birthday” in honor of King Charles’ 74th name day immediately afterward.

The Honourable Artillery Company will also fire a 62-gun salute at the Tower of London an hour later, as per the publication. 

Some members of the British Royal Family have already made their greetings and wishes for the British Monarch known. These include the new Prince and Princess of Wales, who wish him a “happy birthday” on social media, according to MailOnline.

Prince William and Kate Middleton posted a photo of the King using their official account on Twitter. They wrote in the caption, “Wishing a very happy birthday to His Majesty The King!”

The family’s official account on the same platform shared a similar post earlier on Monday, with the caption: “Wishing His Majesty The King a very happy birthday today.” It comes with a snap of a smiling King Charles III.

Elsewhere in the report from Express UK, published Monday, it recalled that Buckingham Palace has yet to announce whether the British Monarch would follow the royal tradition of having a separate official birthday celebration.

The publication explained that King George III started the tradition in 1760, noting that the celebration is a public one, marking the sovereign’s official birthday.

During her reign, Queen Elizabeth II, whose actual birth month was April, followed the custom and celebrated her official birthday on the second Saturday of June, with the Trooping the Colour parade marking the day.

Even so, BBC said it is too early in his reign to make any announcement regarding the matter.

King Charles III ascended to the British Throne following the passing of Queen Elizabeth II earlier in September. Also, he has yet to be crowned as his and Queen Consort Camilla’s coronation will take place at Westminster Abbey on May 6, 2023.

The publication later shared that while there is very little information about how the British Monarch would celebrate his day in private, it recalled that the royal enjoyed memorable birthday celebrations in the past as the Heir Apparent and Prince of Wales.
