Association with the transition from warm to cold weather, and its related status as the season of the primary harvest, has dominated its themes and popular images. In the Southern Hemisphere the seasons are opposite and Autumn starts March 1st. Many cultures feature autumnal harvest festivals, often the most important on their calendars. There are also the many Indian festivals tied to harvest of autumnally ripe foods gathered in the wild, the Chinese Mid-Autumn or Moon festival, and many others. The predominant mood of these autumnal celebrations is a gladness for the fruits of the earth mixed with a certain melancholy linked to the imminent arrival of harsh weather.
Autumn in poetry has often been associated with melancholy. The possibilities of summer are gone, and the chill of winter is on the horizon. Skies turn grey, and many people turn inward, both physically and mentally.
Fashion is heavily influenced by the changing of seasons.
