The Harry Potter Wizarding Almanac is an illustrated reference companion to J.K. Rowling's seven-book Harry Potter series. Rather than following a narrative arc, the book is organized thematically into seven main sections, plus a wizarding timeline and appendices. It compiles factual details, character profiles, maps, diagrams, lists, and direct quotations from the novels to serve as a comprehensive guide to the fictional wizarding world. Seven illustrators contribute artwork throughout, each bringing a distinct visual style.
The book opens with an illustrated timeline spanning roughly a thousand years, from the founding of Hogwarts School of Witchcraft and Wizardry through the major events of Harry Potter's life up to 1998. Quotations from characters including Harry's classmate Hermione Granger, Headmaster Albus Dumbledore, and Rubeus Hagrid, the school's Keeper of Keys and Grounds, frame the chronology.
The first section, "The Witches and Wizards Who Lived," introduces the series' major characters through detailed profile pages. Harry Potter's entry lists his biographical data (born July 31, 1980), his home at Number four, Privet Drive, his holly-and-phoenix-feather wand, his stag Patronus (a magical guardian in animal form), and his many titles, including "The Boy Who Lived" and "The Chosen One." His family members are identified, from his wizard parents James and Lily Potter to his non-magical (Muggle) relatives the Dursleys. The section reproduces Harry's Hogwarts acceptance letter and the required first-year equipment list, and relationship diagrams map the bonds between characters across his life. Profiles follow for Harry's best friend Ron Weasley, with his many nicknames and hand-me-downs; Hermione, whose extensive rule-breaking is meticulously cataloged; and Luna Lovegood, a student in Ravenclaw (one of the school's four houses) who believes in fantastical creatures such as Crumple-Horned Snorkacks. Additional profiles cover fellow Gryffindor Neville Longbottom, Hagrid, Dumbledore, Harry's Slytherin rival Draco Malfoy, Hogwarts professor Severus Snape, and Lord Voldemort, the dark wizard who killed Harry's parents and is his primary antagonist, whose birth name is printed as Tom Harvoro Riddle.
The second section, "Sports, People, and Everything Wizarding," surveys daily life in the magical world. It explains the Statute of Secrecy, enforced since 1692 by the International Confederation of Warlocks (a global wizarding governing body), which requires the magical community to remain hidden from Muggles through both practical and magical concealment methods. The section covers wizarding communication, from owl post and fireplace conversations via Floo powder to Patronus messengers and the Protean Charm (which makes separate objects mirror each other's changes). Modes of magical travel receive extensive treatment: broomstick models, the Floo Network, Portkeys (everyday objects bewitched to transport wizards), Apparition (instantaneous self-transport), the Knight Bus, the Hogwarts Express, and unusual options such as flying cars, dragons, and Thestrals (skeletal winged horses visible only to those who have witnessed death). The section catalogs wizarding food, clothing, celebrations, sayings, and superstitions. A thorough treatment of Quidditch explains the sport's rules, including the Seeker's role in catching the Golden Snitch (a small, fast-flying ball worth 150 points), and traces its history from origins on Queerditch Marsh to the 1994 World Cup final between Ireland and Bulgaria.
The third section, "Spellbinding Spaces and Peculiar Places," maps and describes key locations. An illustrated map of Britain shows Hogwarts in Scotland, Hogsmeade (Britain's only entirely non-Muggle settlement), and London landmarks including the Leaky Cauldron, Diagon Alley, the Ministry of Magic, and St. Mungo's Hospital. Individual shops receive detailed treatment, including the Apothecary, Ollivanders wand shop (operating since 382 BC), and Weasleys' Wizard Wheezes, a joke shop run by Ron's twin brothers Fred and George. Number twelve, Grimmauld Place is described as the ancestral home of the Black family and headquarters of the Order of the Phoenix, Dumbledore's organization formed to fight Voldemort. The house is hidden by a Fidelius Charm, a spell that conceals a secret within a single person. The Burrow, the Weasley family home, is profiled with its enchanted family clock and garden requiring regular de-gnoming.
The fourth and largest section, "An Invitation to Hogwarts," provides a comprehensive guide to the school. It describes the Sorting Hat (bewitched by the four founders to contain their collective intelligence and assign students to houses), profiles each house with its values and common room, and details the school year calendar. The Hogwarts ghosts are profiled, including Nearly Headless Nick and Peeves the poltergeist, whose 1876 standoff with the school ended only after he negotiated additional privileges. The section covers Dumbledore's office with its Pensieve (a stone basin for viewing stored memories), the House Cup point system, the Marauder's Map (an enchanted parchment showing every person and passage in Hogwarts), professors and their subjects, and student organizations. A subsection traces the formation of Dumbledore's Army (DA), a secret student defense group organized in 1995 after Ministry-appointed professor Dolores Umbridge refuses to teach practical defense magic. Twenty-eight students meet secretly in the Room of Requirement, a magical chamber that appears only when a student needs it, using Hermione's Protean Charm-enchanted coins for covert communication. A catalog of magical mishaps rounds out the section.
The fifth section, "Spells, Charms, and Unforgivable Curses," covers wandlore, spellcasting, and specific branches of magic. It explains how each wand's character depends on its wood, core, length, and flexibility. Incantations are listed with their effects, and subjects such as Divination, Transfiguration, and Potions are treated in detail, including brewing instructions with annotations attributed to the Half-Blood Prince, the mysterious former owner of a marked-up potions textbook. The section explains the three Unforgivable Curses (Imperius, Cruciatus, and the Killing Curse Avada Kedavra), the Patronus Charm with each character's animal form cataloged, werewolves and their management with Wolfsbane Potion, and Time-Turners (devices that allow the wearer to travel back in time). It also covers the Mirror of Erised (which shows the viewer's deepest desire), Occlumency (magical defense against mental intrusion), Legilimency (the extraction of feelings and memories from another's mind), and the Death Eaters (Voldemort's followers), who are united under the Dark Mark, their skull-and-snake brand and sky symbol. Catalogs of Fred and George Weasley's pranks and portable magical objects complete the section.
The sixth section, "Ministering Magic and Inspiring Institutions," surveys the Ministry of Magic (established 1707), mapping its departments floor by floor through the Department of Mysteries, where researchers study magic's greatest secrets in chambers including the Hall of Prophecy. St. Mungo's Hospital, Gringotts Wizarding Bank (run by goblins, with its currency system of Knuts, Sickles, and Galleons), and the prison of Azkaban (guarded by Dementors, spectral creatures that feed on human happiness) are each profiled. The Order of the Phoenix is described with its membership and Patronus-based communication system.
The seventh section, "Beasts, Beings, and Botanicals," surveys the magical natural world. Wizarding pets are profiled, from Harry's owl Hedwig to Dumbledore's phoenix Fawkes. Household pests include Cornish pixies, gnomes, Doxies (venomous fairy-like creatures), and Boggarts (shape-shifters that take the form of a viewer's greatest fear). Ten dragon breeds are described with their habitats and behaviors. Care of Magical Creatures lessons cover Hippogriff etiquette (Hippogriffs are magical creatures that are part eagle and part horse) and the Blast-Ended Skrewt project, which involves raising dangerous hybrid creatures with explosive rear ends. Hagrid's personal pets, including the three-headed dog Fluffy, the dragon Norbert, the hippogriff Buckbeak, and Aragog (a giant Acromantula, or enormous talking spider), are profiled. The Forbidden Forest and its inhabitants are illustrated, and Herbology covers magical plants from Mandrakes to Venomous Tentacula. A world map shows the global distribution of fantastic beasts.
The appendices compile every named character from all seven novels, a complete list of Ministers of Magic from 1707 to the present, the full lyrics to "Weasley Is Our King," a catalog tracing the significance of the colors green and purple through the series, a price list of wizarding goods and services, and a year-by-year chronicle of notable owl deliveries.
