If the tree leaves start turning yellow and falling as soon as September appears on the calendar, then the autumn season has officially begun. Autumn is the third season of the year, marking the transition from the warmth of summer to the cold of winter. Traditionally, autumn starts on September 1st and ends on November 30th. However, this year, the official astronomical start of autumn will be on September 22nd, which is the autumnal equinox—the day when day and night are approximately equal in length.
