On the Chinese lunar calendar, “Autumn Equinox” is the beginning of autumn and this day is just at the middle point between “Autumn Begins” to “Hoar-Frost Falls”.It arrives on September 22 to September 23 each year when the sun reaches the celestial longitude of 180 degrees.

在中国农历的节气中，秋分意味着秋天的正式开始，这也是正处于立秋和霜降之间，每年秋分是在9月22-23日之间，太阳达到天文经度180度。Equinox这次词源自于拉丁语意思是白天与夜晚等长，而秋分这一天也是昼夜等长的一天。之后白昼变短，黑夜变长。

It is a good season to enjoy sweet-scented osmanthus full blossom around Autumn Equinox. At this time, it is hot in the day and cool in the night in South China, so people have to wear light clothing when it is hot, and put on more clothes when it is getting cooler. This period is named as "Gui hua zheng" in Chinese, which means osmanthus mugginess.
