Dear 2ccw-ga,
I assume you mean the autumnal equinox.
This year it was on September 22, at 22:23 Greenwich Mean Time.

These pages will give you some additional information.
?In astronomy, the autumnal equinox (fall equinox, September equinox,
or southward equinox) signals the beginning of autumn in the northern
hemisphere: the moment when the sun appears to cross the celestial
equator, heading southward; the equinox occurs around September
22?September 24, varying slightly each year according to the 4-year
cycle of leap years in the Gregorian Calendar.?
