Seven is an important number in the Harry Potter universe. It is the number of books in the series, the number of movies, and the number of Horcruxes that Harry Potter had to destroy. It is also the age at which a wizarding child discovers their magical abilities.
The number seven is symbolic of completion and perfection in the Harry Potter series. It is the number of Horcruxes that Harry Potter had to destroy in order to defeat Lord Voldemort. The seventh Horcrux was actually Harry himself, which is why he had to sacrifice himself in order to defeat Voldemort.
The number seven is also associated with Hogwarts. Before children go to the wizarding school, it is believed that they will discover their magical abilities at the age of seven. This is why Harry Potter received his Hogwarts letter on his eleventh birthday, as he had already been aware of his magical abilities for four years.
