The word “October” is used in literature not only as a temporal marker but also to evoke a particular atmosphere, often rich with historical and emotional significance. In historical narratives and diaries—such as those detailing explorations by Lewis and Clark [1, 2, 3, 4, 5, 6]—October precisely anchors events in time, lending authenticity and context to accounts of discovery and change. At the same time, authors use October’s autumnal imagery to create moods ranging from nostalgic and reflective to eerie and ominous, as seen in the works of Mary Shelley [7] and Bram Stoker [8, 9]. Even in more poetic or symbolic contexts, where the month is used for its seasonal connotations of transition and impermanence, writers like Walt Whitman [10, 11] and others [12, 13] draw upon October’s dual role as both literal and metaphorical signifier.
