Here are some indicators:
* Fashion and Technology: The series features elements like horse-drawn carriages, gaslights, and old-fashioned clothing, which suggests a time before widespread car usage and modern technology.
* Social Norms: The series portrays a more traditional social structure, with strict gender roles and a focus on family reputation, which aligns with the late 19th or early 20th century.
* Language and Writing Style: The language and writing style of the series, while playful and whimsical, also hints at a slightly older era.
While the exact year remains ambiguous, the overall context and setting point to a period between the late 1800s and the early 1900s.
