March 21 and September 23 are the approximate dates of the vernal and autumnal equinoxes which are considered to be the beginnings respectively of the astronomical spring and autumn seasons. The astronomical seasons are heavily promoted by the mass media, but are no more "official" than any other method of reckoning seasonal change. The World Meteorological Organization designates March 1 and September 1 respectively as the first days of the climatological spring and autumn seasons. Ecologically, spring begins locally with the start of the growing season which in temperate climates can be as early as February or as late as May depending on latitude and topography. The ecological autumn season begins locally when the leaves of deciduous trees turn colour and fall to the ground.
