Time is passing by in the blink of an eye for the Swedish royal court.

After all, Princess Estelle, 11, and Prince Oscar, 7, appeared all grown up during recent festivities in honor of their mom Crown Princess Victoria's 46th birthday.

The family marked the occasion with photographs outside the Solliden Castle on July 14, where Victoria was also serenaded by the Borgholm's cultural school's children's choir.

In the snapshots, Victoria and her husband Prince Daniel were all smiles as they posed next to their children for a group portrait. While Victoria—the heir to the Swedish throne—and her mini-me Estelle donned off-white dresses, Daniel and Oscar stepped out in tuxedos.

Other images from the day show the family of four riding in a horse-drawn carriage and waving to a crowd of supporters outside the castle grounds. Victoria was also joined by her parents King Carl Gustaf, 77, and Queen Silvia, 79, for photos.

During the evening, Victoria and other members of the royal family were treated to a birthday concert—aptly called the Victoria Concert—at the Borgholm's castle ruins, the Swedish royal court said in an Instagram post.

Victoria capped off the concert by awarding the "Victoria Prize" to San Jose Sharks hockey player Erik Karlsson.

The heir's birthday is recognized as public flag day in Sweden, as well one of the Armed Forces' official salute days. According to the Swedish royal court, "salutes will therefore be fired from the country's salute stations to mark the day."
