When was First Day of Fall in 2009?

First Day of Fall in 2009 was on Tuesday, the 22nd of September (22/9/2009).

How are First Day of Fall dates determined?

On the equinoxes the Sun shines directly on the equator and the length of day and night is nearly equal - but not quite. The Autumnal or September Equinox is when the Sun crosses the celestial equator, moving from north to south. This date is considered to be the first day of Fall for countries in the Northern Hemisphere.
