The official first day of the astronomical fall in 2011 as mandated by the International Astronomical Union is September 23 for the northern hemisphere and March 20/21 (depending on the time zone) for the Southern Hemisphere.
The official first day of the climatological fall as mandated by the World Meteorological Organization is always September 1 local time for the northern hemisphere and March 1 local time for the southern hemisphere.
Canada and the USA customarily observe the astronomical fall while Australia and New Zealand observe the climatological fall. Preference for either of these methods varies in other western countries. Many east Asian countries use lunar dates to determine the beginning of fall and the other seasons.
In temperate climates, an ecological fall can be determined that starts when most birds begin their migrations to their wintering grounds or when the leaves of deciduous trees turn color and fall to the ground.
