They will now no doubt be keen to begin their first full year in their new expanded roles as Prince and Princess of Wales.
However, it's also been a sad time for Prince William, as his godfather has been ill in hospital.
According to the Greek newspaper Kathimerini, 82-year-old King Constantine II has been in intensive care for a number of days and remains in critical condition following a stroke.

King Constantine, who is also a cousin of the late Prince Philip, is currently being surrounded by members of his immediate family in a private hospital, including his wife of 58 years, Queen Anne-Marie, and their children.
It is also understood that his sisters Queen Sofía of Spain and Princess Irene have already touched down in Greece. While he shares an extremely close bond with his godfather, Prince William is yet to comment on the news.
