When Frederik X stepped out on the Amalienborg balcony on 26 May to mark his 58th birthday, the balcony looked a little lonelier than last year. On one side - his wife Queen Mary in an ice-blue Armani creation with a rose-shaped brooch, and two of the children, Princess Josephine and Prince Vincent. On the other side - four places that weren't filled. And the most painful one, missing behind all the ceremonies, belonged to his mother.

Former Queen Margrethe, who abdicated in his favour in January 2024, was not on the balcony at that moment - she is in hospital. On 14 May she suffered angina and underwent emergency balloon angioplasty on a coronary artery. After a week she was discharged. Seven days later she was back - with a CT scan revealing a significant blood clot in the hip, the consequence of an earlier fall. This is her second hospitalisation in the same month, and the official Danish court is weighing its words: it's hard to call it „routine" when there are two non-routine procedures in two weeks.

The behaviour of the couple's two oldest children also stood out: Crown Prince Christian (20) and Princess Isabella (19). Neither of them appeared on the balcony. The court isn't giving an explanation. They could be in exams, could be on family commitments, could be claiming personal space - and that's fine. But in court protocol, absence from the father-king's 58th birthday is not an invisible thing.

For his birthday Frederik released three official portraits, one in black and white, taken in the throne room of Christiansborg Palace. In full military uniform with multiple decorations. The idea of the portraits is to project stability - that the court is functioning, that the transition from Margrethe to Frederik is complete. The reality is that this transition comes with family costs that show themselves precisely on days that are supposed to be „a happy day."

Royal Run, the sports event Frederik founded in 2018 when he turned 50, was held a few days before the birthday - with the whole family taking part alongside thousands of Danes. The view from a distance: the Danish monarchy works, moves, has a closeness to the people that other European royal houses don't have. The close-up view: 58 is the age at which the main thing on the birthday isn't the cake, but the phone messages from doctors about your parents.
