What day is September 23rd?

September 23rd is the autumnal equinox in China's traditional solar terms.

The autumnal equinox is the middle of autumn, and it is also the time when day and night are equally divided and yin and yang are balanced. On the day of the autumnal equinox, the sun shines directly on the equator of the earth, and the northern hemisphere begins to enter autumn and the southern hemisphere begins to enter spring.

At this time, the weather gradually turned cold, the temperature dropped, the temperature difference between day and night increased, and plants began to sleep. People will also make corresponding adjustments, such as adjusting diet and sleep. The autumnal equinox is also a solar term before the Double Ninth Festival. In ancient times, there were traditional customs such as climbing mountains to enjoy the scenery, enjoying chrysanthemums and inserting dogwood.

The autumnal equinox not only occupies an important position in the traditional culture of the Chinese nation, but also is listed as the intangible cultural heritage of the world. On this day, many areas will hold autumn celebrations, such as autumn outing, chrysanthemum appreciation and catching autumn flavor, to express people's gratitude to nature.

The characteristics of rapid cooling in autumn make "Sanqiu solar terms for health" particularly tense in the busy autumn harvest, autumn ploughing and autumn planting. The autumnal equinox is a good time to harvest cotton and tobacco leaves from green to yellow. Winter wheat has been planted in North China, and the Yangtze River basin and vast areas in the south are busy harvesting late rice and ploughing the land to prepare for rape sowing.

Drought and lack of rainfall or continuous rainfall in autumn equinox are the main unfavorable factors affecting the normal operation of Sanqiu, especially the continuous rainfall will make the upcoming crops lodging, mildewing or sprouting, resulting in serious losses.

"Sanqiu" is a great help, and the word "early" is the key. Timely harvest of crops in autumn can avoid the harm of first frost and continuous rain, and timely sowing of crops in winter can make full use of heat resources before winter, cultivate strong seedlings to survive the winter safely, and lay the foundation for high yield in the coming year.
