This will be similar to how the celebrations were conducted last year, where other members of the royal family were not in attendance and the ceremony was broadcast on TV.
At the time, a small, brief, military ceremony took place at Windsor Castle to mark the Queen's official 94th birthday, and it was all conducted in accordance with strict social distancing guidelines.
Despite last year's low-key celebrations, the Queen looked to have thoroughly enjoyed herself as she was seen nodding along to the music played by the Band of the Household Division.
The event will mark the Queen's first birthday since the death of Prince Philip on 9 April.

The monarch undertook two virtual audiences. The meetings, which took place via video link from Windsor Castle, were with the ambassador from the Republic of Latvia, and the ambassador from the Republic of Côte d'Ivoire.
Her Excellency Mrs. Ivita Burmistre was received in audience and presented the Letters of Recall of her predecessor and her own Letters of Credence as ambassador from the Republic of Latvia to the Court of St. James's.
Her Excellency Mrs. Sara Affoué Amani was also received in audience by the Queen and presented the Letters of Recall of her predecessor and her own Letters of Credence as ambassador from the Republic of Côte d'Ivoire to the Court of St. James's.
Other royals have also been out for official engagements, including Princess Anne and her husband, Timothy Laurence, who marked Anzac Day.
The event will be scaled back from larger instances
Anzac Day - April 25 - marks the anniversary of the start of the First World War Gallipoli landings, and is a national day of remembrance for Australia and New Zealand.
During the engagement, which had a reduced number of attendees due to COVID-19, Princess Anne was pictured laying a wreath at both the Australian and New Zealand War Memorials and signing a book of remembrance.
The event was also marked by the Duke of Cambridge who shared a message with the New Zealand and Australian High Commissions in London, along with some Anzac biscuits, on Friday morning.
In his message, he paid tribute to the "indomitable spirit" and "courage" of Australian and New Zealand forces.
