Traditionally autumn is from September 21 and ends December 21. It is considered to start with the September equinox (21 to 24 September) and end with the winter solstice (21 or 22 December). Popular culture in the United States associates Labor Day, the first Monday in September. The sights, the smells and the feel of autumn are lovely. The changing leaves, the smell of woodsmoke, and the feeling of crip air and soft warm scarfs. Wrap up warm and spend an afternoon in the forest, enjoying the dazzling show that the autumn trees provide.
