The autumn equinox is September, usually the 22nd or 23rd, in the Northern hemisphere. There are two equinox, the autumnal and vernal. They are referred to these name everywhere, in both the northern and southern hemispheres.

Different places have different definitions for when summer begins and ends. I go by the rule that summer begins at the moment of the summer solstice and ends at the moment of the autumnal equinox. In the northern hemisphere the date of the summer solstice ranges from June 19 to June 23, and the date of the autumnal equinox ranges from September 21 to September 24. In the southern hemisphere the date of the summer solstice ranges from December 20 to December 23, and the date of the autumnal equinox ranges from March 19 to March 22.
The vernal equinox is in March in the northern hemisphere and in September in the southern hemisphere.
It starts during the Autumnal equinox (22-23 September).
