The 28-year-old Princess Eugenie and Jack Brooksbank have been dating for seven years and will exchange vows at St. George's Chapel in Windsor.
The ceremony will take place on October 12th. It falls on a Friday, unlike the Duke and Duchess of Sussex, who united in matrimony on a Saturday.
Their engagement was announced on January 22nd, and the official Duke of York Twitter account shared their engagement photo with their 218,000 online followers.
Princess Eugenie shares a close bond with her older sister, Beatrice, who will be the maid of honor on her big day.
Unlike Prince Harry, Princess Eugenie won't need the Queen's blessing to get married because she is not a 'working royal.' Her husband also won't receive a Dukedom, as reported by Telegraph.
'As a father, my wish for my daughters is for them to be modern working young women, who happen to be Members of the Royal Family, and I am delighted to see them building their careers.'

As reported by Good Housekeeping, the quaint St George's Chapel is a favorite among Royal couples, who consider the chapel to be a 'low-key' venue.
Besides Prince Harry and Meghan, other couples who wedded at the chapel include Prince Edward and Sophie Rhys-Jones, as well as Queen Elizabeth II's eldest grandson Peter Phillips and Autumn Kelly.
With only 800 seats, it's a much smaller chapel when compared to St. Paul's Cathedral, or Westminster Abbey, where Princes William and Kate exchanged vows.
Eugenie leads an active and busy lifestyle. Six years ago she cycled through London to raise donations for the Royal National Orthopaedic Hospital.
She also takes their conservation of elephants seriously and is Patron of the Elephant Family. Other causes close to her heart include cancer awareness, osteopathic education, theatre, and art.
Back in March, Eugenie teamed up with her mother, Sarah Ferguson, and sister to 'support @teenage_cancer on their incredible and important work helping teenagers fight cancer.'
