Seven is the most powerful magical number, based on centuries of mythology, science, and mathematics, and therefore has 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.
The Arithmancer, Bridget Wenlock (1202–1285) was the first witch to establish the magical properties of the number seven. 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.

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.)
