But honor the complexity. When someone says “autumn,” they might mean the astronomical transition from equinox to solstice, the ancient harvest months of August through October, or the crisp, ephemeral feeling of a single October afternoon. The true months of autumn are not just marks on a page—they are the weeks when the light slants gold, the air smells of smoke and damp earth, and the world prepares for a long quiet. And that feeling can begin in late August and linger into early December, regardless of what any calendar insists.
The Celtic calendar, which heavily influences modern Neopagan celebrations like Mabon and Samhain, divided the year into two primary seasons (summer and winter), with autumn as a transitional period. However, the traditional Gaelic festival of Lughnasadh (August 1) marked the beginning of the harvest season, and Samhain (November 1) marked the end of harvest and the start of winter. Under this lens, “autumn” as a distinct season spanned August, September, and October —with August being the early harvest, September the main harvest, and October the final gathering before the dark half of the year. what months are autumn
In traditional East Asian culture, the year is divided into 24 solar terms. Autumn begins with Lìqiū (“Start of Autumn”), which usually falls around August 7 or 8 , and ends with Shuāngjiàng (“Hoar Frost Descends”) in late October, leading into Lìdōng (“Start of Winter”) around November 7. Thus, in the Chinese system, autumn effectively occupies August, September, and October —a full month earlier than the meteorological definition. But honor the complexity
