"...isn't seven the most powerfully magical number, wouldn't seven-?"
Tom Riddle discusses the power of the number seven[src]
Seven is the most powerful magical number,[1] based on centuries of mythology, science, and mathematics.

Bridget Wenlock.

Wizarding community

The Arithmancer Bridget Wenlock (12021285) was the first witch to establish the magical properties of the number seven.[2]

Seven is the age by which most experts believe that magic will reveal itself in a wizard or witch.[3] In the life of the Hogwarts School of Witchcraft and Wizardry community, it is the number of years students must attend Hogwarts before graduating. There were seven chambers protecting the Philosopher's Stone. Lord Voldemort was such a believer in the magical properties of the number seven that he intended to split his soul into seven portions by creating six Horcruxes. Ironically, he instead succeeded in creating seven Horcruxes, thus splitting his soul eight ways - however, by pure chance, only six of his Horcruxes ever existed at one time (as the Diary was destroyed before Nagini became a Horcrux); regardless, this did not provide him with any significant magical protection as he believed the number would. Harry Potter and Neville Longbottom were born in July, the seventh month of the year; this made them both potential subjects of a prophecy. Arthur and Molly Weasley had seven children; Ginny Weasley is the seventh of them, and the only daughter. There are also seven players on a standard Quidditch team, with seven also being the number on Harry Potter's Quidditch uniform. During the Battle of the Seven Potters, six others took Polyjuice Potion in order to take on Harry's appearance as a diversion, thus there were seven Potters.

(Note that Harry was in the hospital wing for the Gryffindor vs. Ravenclaw match in his first year. Quidditch was cancelled before Gryffindor could play Hufflepuff or Ravenclaw due to the basilisk attacks in Harry's second year. Harry fell off his broom due to because of dementors and Cedric Diggory got the Snitch in Harry's third year match of Gryffindor vs. Hufflepuff. There were no Hogwarts Quidditch matches in Harry's fourth year because Hogwarts was hosting the Triwizard Tournament. Harry earned a "lifelong" ban from Quidditch after beating up Draco Malfoy, and therefore, Ginny Weasley played Seeker in the Gryffindor matches against Hufflepuff and Ravenclaw. During Gryffindor's match against Hufflepuff in Harry's sixth year, the reserve Keeper, Cormac McLaggen, knocked Harry unconscious with a misaimed Bludger before Harry could get the Snitch, and Harry was put in detention by Professor Snape during the final match against Ravenclaw. Harry did not return to Hogwarts for his seventh year, and therefore could not play Seeker.)

Behind the scenes

  • There are seven books in the Harry Potter series, and eight movies.
  • The first book was released in 1997, and the final book was released in 2007.
  • There are seventeen chapters in the first book.
  • If you count the epilogue, there are thirty-seven chapters in the seventh book.
  • The epilogue itself is set in 2017.
  • The first years enter the castle in the seventh chapter of the first book.
  • Many fans expected Harry Potter and the Deathly Hallows (the seventh book) to be released on 07/07/2007, which also happened to be a Saturday, the day upon which Harry Potter books had previously been released. However, it was released on July 21st of that year instead, two weeks later. It is thought that the more 'magical' date was rejected due to it also being the second anniversary of the 7/7 London Bombings in 2005. (21 is still a multiple of 7 though.)
  • The number on the back of Harry Potter's Quidditch robes in the films is seven (this could be a reference to the fact that usually the best player/captain in a football team, has the number 7 shirt).
  • Chapter four of Harry Potter and the Deathly Hallows is entitled "The Seven Potters".
  • In Deathly Hallows Part 1  Daniel Radcliffe played seven roles - Harry, Ron, Hermione, Fred, George, Mundungus, and Fleur during the Battle of the Seven Potters.
  • In the films, Voldemort is played by seven actors: Richard Bremmer, Ian Hart, Christian Coulson, Ralph Fiennes, Hero Fiennes-Tiffin, Frank Dillane and by Michael Berendt although the latter's scenes were cut and never seen.[4]
  • J. K. Rowling stated in interview that she chose to write seven books in total because she spent seven years in secondary school. Also, she wanted Harry to come of age at seventeen because it "just seems a good number for a wizard to come of age."
  • In the seventh Harry Potter book, J.K. split the dedication in seven parts.
  • J. K. Rowling stated in interview that the "big seven" in the Harry Potter series are: Harry Potter (Daniel Radcliffe), Hermione Granger (Emma Watson), Ron Weasley (Rupert Grint), Ginny Weasley (Bonnie Wright), Neville Longbottom (Matt Lewis), Luna Lovegood (Evanna Lynch), and Draco Malfoy (Tom Felton).[5]
  • There were seven clues and seven opportunities to sign up and register for the Pottermore beta. The first clue was on 31 July 2011 (Harry's birthday) and the final was 6 August 2011. A clue was released each day and each clue was from a book in the series corresponding to the day. For example, day one's clue was from Philosopher's Stone and the final clue was from Deathly Hallows.
  • On 7 August, the Harry Potter series won seven awards at the 2011 Teen Choice Awards for Deathly Hallows: Part 1 and Part 2.
  • The Battle of Hogwarts in on 2 May, the 2nd day of the 5th month. 2+5=7
  • If the letters of the alphabet were turned into numbers (A=1, B=2, etc...), the letters in the name Harry would equal 70.
  • Nicolas Flamel is seven years older than his wife.
  • During Harry's hearing in the Ministry (in 1995), Dumbledore states that clause 7 of the Decree for Reasonable Restriction of Underage Sorcery allows the use of magic in life-threatening situations.
  • In Harry's copy of Fantastic Beasts and Where to Find Them, he wrote in the Pixie section for the classification, "or XXXXXXX if you're Lockhart." He actually mentions seven X's.
  • The first film in the Fantastic Beasts and Where to Find Them trilogy is set 70 years before the Harry Potter series.
