The entire "Harry Potter" series is set from 1991 to 1998 aside from the opening chapter of the first book, which takes place on 1 November 1981, and the epilogue of the seventh book, which takes place on 1 September 2017. At various points throughout the Harry Potter timeline, flashbacks and flash-forwards depict the 1920s, the 1930s, the 1940s, the 1970s, the 1980s, the 2010s, and the 2020s. The depiction of the Wizarding World is centred on magic, which not only imbues objects such as wands, but is portrayed as an inborn ability. It is also centred on the separation of the wizarding world from the non-wizarding (Muggle) world. Despite being an inherent talent, magic is honed through study of various branches of magic and practical training into a skill.
