Spring, also known as springtime, is one of the four temperate seasons, succeeding winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs.
April is the fourth month of the year in the Gregorian and Julian calendars. Its length is 30 days. April is commonly associated with the season of spring in the Northern Hemisphere, and autumn in the Southern Hemisphere, where it is the seasonal equivalent to October in the Northern Hemisphere and vice versa.
May is the fifth month of the year in the Julian and Gregorian calendars. Its length is 31 days. May is a month of spring in the Northern Hemisphere, and autumn in the Southern Hemisphere. Therefore, May in the Southern Hemisphere is the seasonal equivalent of November in the Northern Hemisphere and vice versa.
June—abbreviated Jun or Jun.—is the sixth month of the year in the Julian and Gregorian calendars—the latter the most widely used calendar in the world. June is 30 days long, and comes after May and before July.
