Being a royal baby is fine and all, but when will the newborn HRH Prince of Cambridge be crowned by the Archbishop of Canterbury in Westminster Abbey? Well, if you look at the latest actuarial data from the U.K.'s Office of National Statistics, it won't be until the early 2060s.
For the infant prince to become king, his great-grandmother, grandfather, and father would all have to either die or abdicate the crown. Assuming none of them abdicate and neither Charles, Prince of Wales, nor Prince William, Duke of Cambridge die before their respective royal elder, we can look at the typical life expectancy for a British 31-year-old man to know when the baby will become king.
According to the U.K.'s Office of National Statistics, the life expectancy for an English 31-year-old man is 48.7 years, which would put the expected succession for his son in early April 2062, specifically April 4. Now, the actual coronation would probably take place until much later. Queen Elizabeth II ascended to the throne soon after her father, George VI, died on Feb. 6, 1952, but the coronation took place almost 16 months later, on June 2, 1953.
