I don't know if you're asking about the solar calendar or the lunar calendar, so I'll just say it briefly.

Gregorian calendar 2011September 23rd is the autumnal equinox among the 24 solar terms this year. It is a year in which yin and yang are half, there is no extreme day and night, and the cold and summer are balanced.

20 1 1 September 23rd is the 266th day of the Gregorian calendar year (the 267th day of leap year), and there are 99 days before the end of the year. This day is the "Autumn Equinox". The autumnal equinox is one of the 24 solar terms, which falls on September 23rd or 24th of the solar calendar every year. On this day, the northern and southern hemispheres are as long as day and night.

In the lunar calendar, legend seems to be a full moon day after the Mid-Autumn Festival. This is not very clear. .
