J.K. Rowling’s final main Harry Potter novel was published worldwide on 21 July 2007.
Harry Potter and the Deathly Hallows was released simultaneously in English-speaking markets at one minute past midnight local time. It concludes the seven-book story and follows Harry, Ron, and Hermione as they search for the remaining Horcruxes and confront Lord Voldemort.
The launch was one of the largest publishing events in modern history. Publishers used strict embargoes to protect the plot, while bookstores held midnight celebrations for readers. The novel sold millions of copies immediately and broke first-day sales records in several markets.
The date is distinct from the release dates of the films and from the publication dates of earlier books. Harry Potter and the Half-Blood Prince appeared in 2005, while the film adaptation of Deathly Hallows was divided into two parts released in 2010 and 2011.
