Today, King Willem-Alexander celebrated his 54th birthday! Koningsdag is usually celebrated in a Dutch city and this year it was in Eindhoven, even though most of the celebrations were virtual due to the pandemic.

They first attended a special TV broadcast where they played in a quiz about the Brainport-Eindhoven region against four other families.

Afterward, the family watched a free runner show on a 3 D-printed “Minecraft” course. The 3 Princesses then visited the Oranje Room where they talked to other young people about music and identity. They also raced against each other in three e-race simulators.

In the afternoon, the family attended the rehearsals of the evening concert by The Streamers that would conclude the Koningsdag festivities and they met with the technical staff.
