When was 'the northern lights' by Phillip Pullman set?

"The Northern Lights," also known as "Northern Lights" in some regions and "The Golden Compass" in others, is set in a parallel universe that resembles our own but features distinct differences, such as the presence of daemons—animal companions that represent a person's soul. The story doesn't specify an exact time period, but it draws inspiration from early 20th-century Europe, particularly in its cultural and societal elements. The setting combines fantastical elements with a Victorian-like atmosphere, creating a richly detailed world that feels both familiar and otherworldly.
