Prince Andrew turned 65 on February 19, but his daughters, Princess Beatrice and Princess Eugenie, made no public note of the event.
The sisters, who are not working royals, usually post personal milestones on social media, but this time they were silent.
Eugenie, who has 1.8 million Instagram followers, recently shared a Valentine's Day tribute to her husband, Jack Brooksbank, but no matching message emerged for her father.
Beatrice does not have a public Instagram account, but her husband, Edoardo Mapelli Mozzi, frequently posts on their behalf; he, too, has stayed quiet.
Sarah Ferguson, Prince Andrew's ex-wife, similarly declined to acknowledge the milestone online, despite the fact that she continues to reside with the Duke of York at Royal Lodge in Windsor.
The Royal Family's official accounts, which rarely commemorate non-working royals' birthdays on rare occasions, likewise failed to recognize Andrew publicly.
Following his contentious BBC Newsnight interview concerning his links to Jeffrey Epstein, the Duke of York took a break back from royal obligations in 2019. Since then, he has mostly withdrawn from public life.
