It happens tomorrow: On the first day of fall – the autumnal equinox — day and night are each about 12 hours long (with the actual time of equal day and night, in the Northern Hemisphere, occurring a few days after the autumnal equinox). The Sun crosses the celestial equator going southward; it rises exactly due east and sets exactly due west. (SOURCE: almanac.com)

Wikianswers.com says, “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 customarily observe the climatological fall. Preference varies in other western countries. Many east Asian countries use lunar dates to determine fall and the other seasons.”

All of the above verbiage is just another way of telling us that WINTER IS HEADING THIS WAY!
