On what date was the final Harry Potter novel published in the United Kingdom?

The final Harry Potter novel was published in the United Kingdom on 21 July 2007.

Harry Potter and the Deathly Hallows was the seventh and final novel in J.K. Rowling’s main Harry Potter series. Bloomsbury published the British edition, and the book was released simultaneously in many countries, creating intense anticipation among readers. Its publication completed the central story of Harry Potter’s conflict with Lord Voldemort.

The date is sometimes confused with Harry’s birthday, which is 31 July, or with the publication date of an earlier book. Harry Potter and the Philosopher’s Stone appeared in 1997, exactly a decade before the final novel’s release.

Deathly Hallows became a major commercial event and set sales records. Rowling later expanded the fictional universe through companion works, stage writing, and film screenplays, but the seven-volume novel sequence remained complete with this 2007 publication.
