The Wizarding World of Harry Potter is a series of fictional characters that have passed through hundreds of years of history. In fact, as Hogwarts was founded in 993, there is a millennium's worth of history in the series. There is a wealth of information to sort through, most of it can be vague.
When you think of older characters in the Harry Potter franchise, there are many that have lived for hundreds of years; for example, there are many ghosts, and who might forget Nicolas Flamel, who was almost 700 when he died during his final years of life in the Wizardry school of Hogwarts. Brian Dumbledore was a Professor of Defense Against the Dark Arts before becoming the Transfiguration Professor for a number of years.
You may have wondered how old Dumbledore was during your viewing of the movies or reading the books at some point, just like Harry and his friends did at some point. So let's take a look and let's explain when Albus was born and how he ages at various points in the franchise.
Albus Dumbledore is 75 years old?
Dumbledore's birthday isn't specified in the Harry Potter books, and so fans have discovered clues that indicate when his birthday might have been. Albus' mother died in 1899, while his father was imprisoned in Azkaban for allegedly abusing Dumbledore's sister Ariana.
Albus Dumbledore's Life and Lies, according to Rita Skeeter's book of the same name, was at his 18th birthday when he left Hogwarts. Therefore, his enrollment must have taken place before June.
Fantastic Beasts: The Crimes of Dumbledore is the first film in the Harry Potter saga to feature Dumbledore, which takes place in 1927, making Jude Law's version of the professor a 45-year-old figure. The actor is also roughly the same age as the character in the Harry Potter books and films, starting in 1980, when Harry Potter was born.
Dumbledore formed the Order of the Phoenix against Voldemort and his Death Eaters in the First Wizarding War in 1970, so he was already 89 years old. By the time Harry Potter was born, Dumbledore was either 89 or 88, depending on the month of the old wizard's birthday, as Harry was born on July 31, 1980.
Richard Harris played Dumbledore in the first two films, but he died before the third, so the role was taken up by Michael Gambon. Gambon was 64 years old when he first played the character in Harry Potter and the Prisoner of Azkaban, while Harris was 71 when Harry Potter and the Philosopher's/Sorcerer's Stone was released.
Albus Dumbledore died at the age of 115, after being killed at the top of the Astronomy Tower in Harry Potter and the Half-Blood Prince. He lived a long life, defeating many dark wizards and collecting all of the Deathly Hallows. He also managed to be the Headmaster of Hogwarts for roughly 30 years, teaching many pupils across two different disciplines.
Dumbledore was an old man during all of Harry Potter. You have to wonder how long he would have lived if he hadn't been killed by Snape, or if he hadn't already died from attempting to wielding the Resurrection Stone, which Voldemort had cursed. Nonetheless, he did have a wonderful, although fictional life, one that might have been as long as his beard.
