"Wouldn't it be better, make you stronger, to have your soul in more pieces, I mean, for instance, isn't seven the most powerfully magical number, wouldn't seven--?"
Tom Riddle discusses the power of the number seven[src]

Bridget Wenlock

Seven was the most powerful magical number,[1] based on centuries of mythology, science, and mathematics, and therefore had a very important role in the wizarding world. Arithmancer Bridget Wenlock was the first to note this through a theorem which exposed the magical properties of the number seven.[2]

History

The Arithmancer, Bridget Wenlock (12021285) was the first witch to establish the magical properties of the number seven.[2] She wrote her ground-breaking theorem on the back of a sugar packet, using her usual invisible ink. She then proceeded to send her cousin a letter, forgot where she wrote the theorem, and thought it was on the envelope. She hunted down the envelope and intercepted it at her cousin's house, where she learned her mistake.[3]

Seven was the age by which most experts believed that magic would reveal itself in a wizard or witch.[4]

Behind the scenes

Dates

  • The first book was released in 1997, and the final book was released in 2007.
  • The epilogue itself is set in 2017.
  • 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.)
  • 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
  • The first film in the Fantastic Beasts and Where to Find Them trilogy is set 70 years before the Harry Potter series.

Miscellaneous

  • 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).
  • 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 Harry Potter and the Deathly Hallows, J.K. split the dedication in seven parts.
  • 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.
  • Seven is also a unique number, being the highest, single-digit prime number.
