It is the first of four months to have a length of 30 days, and the second of five months to have a length of less than 31 days. April is commonly associated with the season of autumn in parts of the Southern Hemisphere, and spring in parts of the Northern Hemisphere, where it is the seasonal equivalent to October in the Southern Hemisphere and vice versa.
