Resources to celebrate Harry Potter Book Day, 9 October 2025

Friends and Foes is the theme for Harry Potter Book Day on Thursday 9 October, and Bloomsbury has created a range of downloadable resources to help you celebrate!

Harry Potter Book Day is a special annual event that brings together fans around the globe in a celebration of the iconic book series with events, parties and other festivities.

You can register for a free event kit which is jam-packed with creative and fun decoration, costume, activity and game ideas that celebrate the deep friendships and explore the dark feuds in the Harry Potter books. You can use the event kit - or create your own magical activities for the day!

Whether you are a bookshop, library, school or group of friends who want to celebrate, the event kit has activities for readers of all ages, and is suitable for all readers, from lifelong superfans to young readers just beginning their Harry Potter journey. The kit also includes special activities and guidance for schools.

The wizarding world is full of opportunities to make the greatest of friends, including our favourite trio Harry, Ron and Hermione, and face down the deadliest foes (stay away Death Eaters!) The event kit is packed full of creative and exciting activities that celebrate the deep friendships and explore the dark feuds in the Harry Potter books.  Find out more at the Bloomsbury website.
