Astronomically, it begins with the autumnal equinox (around September 23 in the Northern hemisphere, and March 21 in the southern hemisphere), and ends with the winter solstice (around December 21 in the Northern hemisphere and June 21 in the Southern hemisphere). However, meteorologists count the entire months of March, April and May in the Southern hemisphere, and September, October and November in the Northern hemisphere as autumn. An exception to these definitions is found in the Irish Calendar which still follows the Celtic cycle, where Autumn is counted as the whole months of August, September and October.

The exact date and time of the Autumn Equinox varies from year to year. This is when the sun moves into the astrological sign of Aries and daylight time equals that of darkness, (indicating the start of Autumn). Each year, the date/time moves progressively later in September until the year before leap-year is reached. On leap-year, it returns to an earlier date/time. This four-year cycle is then repeated. For 2006: 23rd Sept @ 04:03. Time is in UT (Universal Time); this used to be called Greenwich Mean Time or GMT.

To my mind, there are 4 seasons, so i divide the 12 months up to fit the seasons.
Spring = March, April and May
Summer = June, July and August
Autumn = September, October and November
Winter = December, January and February.
So to me it's Autumn now.

21st September is the Autumn Equinox. So I tend to see that as the first day of Autumn.
