There are a lot of similarities between Queen Elizabeth II and the late Jacqueline “Jackie” Kennedy Onassis. 

Both women remain style icons — the leader of the British monarch for her brightly colored suits, worn so she’s easily identifiable in a crowd — and Jackie for her modern and timeless style that’s still relevant today, decades after her passing. 

And, of course, their age. If Jackie were alive today she’d be of a similar age to Queen Elizabeth II. Learn more about their birthdays ahead. 

When is Queen Elizabeth II’s birthday? 

Born Princess Elizabeth Alexandra Mary on April 21, 1926, Queen Elizabeth II celebrates her birthday twice a year. First, on her actual birthday then again on the second Saturday in June because London weather is much more suitable to a parade, known as Trooping the Colour, at that time. 

During her official birthday in June, British people turn out to see Queen Elizabeth II and many members of the royal family participate in a parade with a Royal Air Force flyby after, during which the family stands on the balcony of Buckingham Palace.

According to the British royal family’s website, if a sovereign’s birthday doesn’t naturally fall during the months of June, July, or August, a summer date will be picked to mark the occasion meaning there are two birthday celebrations.

Queen Elizabeth II is known to celebrate her actual birthday privately with her family. The day is marked publicly with gun salutes: According to the website, there’s “a 41 gun salute in Hyde Park, a 21 gun salute in Windsor Great Park, and a  62 gun salute at the Tower of London,” at “midday” or noon. 

What’s the birthdate of Jacqueline Kennedy Onassis? 

Born Jacqueline Lee Bouvier on July 28, 1929, three years younger than Queen Elizabeth II, Jackie’s birthdays differed greatly. 

She didn’t become famous until she began dating John F. Kennedy as a young adult in 1952 after he reportedly leaned over a dish of asparagus to ask her on a date.

The couple married on September 12, 1953, and would go on to become president and first lady of the United States. 

Jackie likely only experienced a similar level of pomp and circumstance to Queen Elizabeth II on her birthday as First Lady of the United States. 

After the assassination of her husband, Jackie remarried, becoming Jackie O. or Jackie Onassis, when she married Greek shipping tycoon, Aristotle Onassis, in 1968. She became a widow again in 1975 and retreated into life as a private citizen.

Although Queen Elizabeth II and Jackie were close in age and did share many similarities, one of the big differences in their lives is that Jackie spent the majority of her life in private.

Her birthday celebrations and lack of details surrounding them are in stark contrast to those of Queen Elizabeth II, who has celebrated her birthday as a world leader for most of her life with Trooping the Colour.
