What does beginning of autumn mean? What does beginning of autumn mean?

On August 7th or 8th every year, beginning of autumn is considered as the time when the sun reaches 135. Beginning of autumn's "stand" means the beginning, and "autumn" refers to the maturity of crops. Beginning of autumn means that summer will cool down and autumn will begin. This is a solar term that reflects the season.

According to "Twenty-four solar terms": "Autumn is also contending, and things gather here". Beginning of autumn not only indicates that hot summer is coming, but also autumn is coming. It also means that the vegetation begins to bear fruit and children, and the harvest season is here. At this time, early rice harvesting and late rice transplanting in Central China, autumn crops entered an important growth and development period.

The ancients regarded beginning of autumn as an important moment at the turn of summer and autumn, and always attached great importance to this solar term. According to records, the plane tree planted in the basin was moved into the temple by Li Qiuqiu Palace in the Song Dynasty. It's time for "beginning of autumn". Tai Shigong shouted, "Autumn is here." After the play, the phoenix tree dropped one or two leaves to express autumn.

Beginning of autumn has arrived, but not in autumn. The division of climatic seasons should be based on the "average climate temperature", that is, the local average temperature is below 22℃ for five consecutive days, which is the real autumn. China is a vast country. Although the climate varies from place to place, most of them have not yet entered the autumn climate, and the last days of the dog days are still the third day after beginning of autumn.

Especially in the south of China, this solar term is still a hot summer. At the same time, because the typhoon and rainy season are about to pass and the temperature is even hotter, TCM calls the period from beginning of autumn to the autumnal equinox "long summer".

Characteristics of beginning of autumn

Beginning of autumn means rain, storm, humidity, etc. At the turning point of the year, it tends to decline or decrease. Seasonal changes, rainfall, rainstorm, dry and wet changes in southern China are obvious; In the northern region, these changes are not obvious, but the temperature is obvious. After entering autumn, in nature, the qi of Yin and Yang began to change, everything began to grow from lush to mature, and the climate began to transition from rainy and humid in summer to dry and rainy in autumn. The beginning of autumn does not mean the end of hot weather. As the saying goes, "the summer heat is in dog days", according to the calculation method of "dog days", beginning of autumn is often in dog days until the summer heat, so the weather is still very hot in early autumn, and it will generally get cold after the Millennium solar terms. The watershed of summer heat is in autumn, not at the turn of summer and autumn. The climate in autumn is divided into two stages, the early autumn is sultry, and the climate tends to be dry and cool after the Mid-Autumn Festival. This is a season of alternating hot and cold.

Is it raining in early autumn?

Rain in early autumn is a natural phenomenon.

Rain in early autumn will quickly lower the temperature and take away the ground temperature by evaporating water. The rain in early autumn will affect the temperature throughout autumn. Therefore, in the era of small-scale peasant economy, people attached great importance to the solar terms in beginning of autumn, but now with scientific and technological means such as greenhouse vegetables, the impact of rain on crops in beginning of autumn is not so great. Therefore, the rain in beginning of autumn has become the basis for judging whether it will be cool in autumn.

How to determine beginning of autumn early and beginning of autumn late?

The ancients did not have a solar calendar, but only followed the lunar calendar. Generally speaking, beginning of autumn is at the turn of June and July in the lunar calendar, so beginning of autumn is earlier in June and later in July.

The period of "cool and hot" should refer to July of the lunar calendar, which is related to the ancient calendar of China. In ancient China, the moon was also recorded according to heavenly stems and earthly branches, and the solar terms became the starting and ending points of the month. Beginning of autumn corresponds to the beginning of the application of the moon, that is, the seventh month of the year. In addition, beginning of autumn usually appears at the turn of June and July in the lunar calendar, so people compare the relationship between cold and heat in July in the lunar calendar through the morning and evening in beginning of autumn.

Usually, the beginning of autumn time in the solar calendar is fixed every year, but it will be much worse in the lunar calendar sooner or later. If beginning of autumn is late, we have to calculate the past July of the lunar calendar. For example, this year's beginning of autumn falls on July 12 of the lunar calendar, which belongs to late autumn. When calculating whether the July of the lunar calendar is hot or not, we have to take into account the July of the lunar calendar that has passed before beginning of autumn, that is, July 27th to August 24th in the solar calendar (this corresponds to the month from July 1 day to 29th in the lunar calendar).

And this time is just the dog days, it is difficult to think about it.

If beginning of autumn is early, the situation is just the opposite.

The so-called early autumn, chilly, late autumn, hot cattle, is such a truth.
