Harry Potter was born on July 31, 1980.
J.K. Rowling was born on July 31, 1965.
The match is deliberate, and it is one of several pieces of her life she slipped into the boy who lived.
The date: July 31
Rowling was born at Cottage Hospital in Yate, Gloucestershire. (Some profiles, including a CBS News timeline, place her birth in nearby Chipping Sodbury, but Yate is the correct town)
Harry is 15 years younger.
In the first book, he turns 11 at midnight on July 31, 1991, the night Hagrid breaks down the door of the hut on the rock and hands him a squashed chocolate birthday cake.

Rowling gave Harry her birthday on purpose. Education World reported Rowling saying she had become so close to Harry that she let him have her birthday.
CBC described it as a connection the author made sure of.
Other parts of Rowling inside the books
The birthday is one of several personal touches. Hermione is the most famous.
Rowling has said the bookish know-it-all is loosely based on her: “She’s a caricature of me when I was eleven.”
Her pen name has a family story as well. Rowling has no middle name, and when her publisher asked for 2 initials, she explained in 2001:
“I gave myself my favourite grandmother’s name as a middle name.”
That name was Kathleen.
The Hogwarts Express comes from her parents.
Peter and Anne Rowling met on a train out of King’s Cross in 1964. This is why Harry had to leave for school from that station.
July has another important date for her.

Her daughter Jessica was born on July 27, 1993, 4 days before Rowling’s own birthday.
She told CBC in 2000 that the happiest moment of her life was “having my daughter handed to me in the hospital.”
Harry’s birthdays in the books
Rowling used the date again and again.
Harry’s birthdays are almost always miserable at the start and better by the end.
His 12th birthday is spent hiding in his room while the Dursleys host a dinner for a client.
Dobby shows up on his bed and ruins the evening with a pudding.
His 13th, in Prisoner of Azkaban, is the first time he gets real presents by owl.

Ron sends a Pocket Sneakoscope from Egypt, Hermione a broomstick servicing kit, and Hagrid the Monster Book of Monsters, which tries to bite him.
At 14, Dudley is on a strict diet and the whole house suffers. Harry’s friends rescue him by owl post with birthday cakes.
His 17th, in Deathly Hallows, is the one that counts in wizard law.
He comes of age, the Trace on him ends, the Weasleys give him a watch, and Minister for Magic Rufus Scrimgeour arrives with Dumbledore’s will.
Born as the seventh month dies
The date matters to the plot. The prophecy about the boy who will defeat Voldemort says he will be born “as the seventh month dies.”
2 boys fit.
Neville Longbottom was born on July 30, 1980, a day earlier.
Voldemort chose Harry, and that choice is what made Harry the Chosen One.

It’s one of the cleverest uses of a birthday I know in children’s fiction, and it all hangs on Rowling’s real date.
Richard Griffiths, which played Uncle Vernon in all 8 films, was born on July 31, by coincidence.
The script book of Harry Potter and the Cursed Child came out on July 31, 2016, the date fans call Harry’s birthday and Rowling’s at once.
Daniel Radcliffe missed the club by a week: he was born on July 23, 1989.
When Rowling turned 50 in 2015, she told the Today show she would celebrate with family and friends. Harry turned 35 that day, a less dramatic party than his 11th.
So the answer to the question is short. Harry has Rowling’s birthday because she wanted him to and she used it more than any other date in the 7 books.
It’s in the first chapter Hagrid appears and in the prophecy that drives the whole saga, which makes July 31 a less random choice than a reader thinks on the first pass.
