Is there any difference between the beginning of autumn and the autumn equinox, and what is the diff

The differences between the autumnal equinox and the beginning of autumn are as follows:

1. The biggest difference between the beginning of autumn and the autumn equinox is the different time. The beginning of autumn is on August 6-9 every year, when the sun reaches 135 degrees of ecliptic longitude. The autumnal equinox is held from September 22 to 24 every year, when the sun reaches 180 degrees of ecliptic longitude.

2. The solar terms and climate are different, the beginning of autumn has arrived, but it is not that the autumn climate has arrived. Therefore, the beginning of autumn does not mean that the hot weather is over, and the weather is still very hot during early autumn. From the day of the autumnal equinox, the days gradually become shorter and the nights longer; The temperature difference between day and night will gradually increase, and the amplitude will be higher than 10; The temperature is dropping day by day, getting colder day by day, and gradually entering the deep autumn season.

1. The position of the sun is different.

The beginning of autumn is on August 7 or 8 of the Gregorian calendar every year, and the sun will turn to the position of 135 degrees of ecliptic longitude. The autumnal equinox is between September 22 and 24 of the Gregorian calendar, and the sun is at 180° ecliptic longitude.

2. The meaning is different.

The beginning of autumn means the official beginning of autumn. The autumnal equinox means to enter late autumn.

The beginning of autumn is the first solar term of autumn, and the beginning of autumn marks the official beginning of early autumn, when the temperature is about the same as in summer, and then the temperature will slowly drop, from hot to cool, from cool to cold, so the beginning of autumn belongs to a transitional season. The autumn equinox is the fourth solar term of autumn, and after the autumn equinox solar term, most parts of our country have entered late autumn.

3. The climatic characteristics are different.

The beginning of autumn is the dog days, the temperature is higher at this time, the heat is unbearable, the temperature is similar to summer, there is an "autumn tiger" after the beginning of autumn, the weather is still very hot at this time. At the time of the autumn equinox, it is already late autumn, and it is a good time for autumn to be high and refreshing. There is a saying that "an autumn rain and a cold" refers to the autumn equinox solar terms.

4. The position of the solar terms is different.

The beginning of autumn is the 13th of the 24 traditional solar terms in China. When it comes to the beginning of autumn, the leaves of the sycamore tree will begin to turn yellow and wither, so there is a saying that "the leaves of the sycamore fall and the world knows autumn". The autumn equinox is the 16th of the 24 traditional solar terms in China.

The autumnal equinox is the 30th day of autumn, and when the autumnal equinox day and night are equinoxes, each accounting for 12 hours, there is no polar day and polar night phenomenon in the world.

5. Other differences.

Three waits for the beginning of autumn: "One waits for the cool breeze to arrive; The second candidate is Bai Lusheng; Three chilling cicadas. "It means that the cool wind is coming, the white dew is beginning to fall, and the cicadas are beginning to chirp.

Three autumnal equinoxes: "One waits for the thunder to begin to end; secondly, stinging insect blank households; Three wait for the water to start drying. "It means that the thunder has begun to decrease, the dormant worms have begun to hide in their burrows, the rainfall has begun to decrease, and some swamps and puddles have begun to dry up.

The beginning of autumn and the autumnal equinox are not the same.

The beginning of autumn and the autumn equinox are two completely different solar terms, the only similarity is that they are the same autumn solar terms, each season has such two similar but different solar terms, the beginning of the spring solar term and the spring equinox solar term; the beginning of summer and the summer solstice solar terms in summer; the beginning of autumn and the autumn equinox; The beginning of winter solar terms and the winter solstice solar terms in winter.

To put it simply: there are "four stands" in a year - the beginning of spring, the beginning of summer, the beginning of autumn and the beginning of winter, which means the beginning of a quarter;

There are "two equinoxes" - spring equinoxes and autumn equinoxes, which can be understood as cutting the time of the year into two halves, and there is a saying that "the time is worth two equinoxes, and the day and night are equally divided". That is, every year on the day of the "spring equinox" or "autumn equinox", the day is as long as the night.

There are "two solstices" - summer solstice, "winter solstice". It can also be understood as cutting the time of the year in half. On the day of the "summer solstice" of the year, the day is the longest and the night is the shortest; On the day of the "winter solstice", the day is the shortest and the night is the longest.

Oops, the autumnal equinox doesn't mean that the autumn is halfway over!!1

These are the two solar terms: the beginning of autumn is the beginning of autumn.

The autumnal equinox is the equinox of day and night. It means that the day is as long as the night, and after this day, the night is longer than the day, which is often said to be the beginning of the day.

The beginning of autumn is the beginning of autumn!

The autumnal equinox means that autumn is halfway over!

Two solar terms!

The beginning of autumn is the beginning of autumn, and the days gradually become shorter, and when the days are shortened to the same as the night, this day is the autumn equinox, I don't know if this is right.

Beginning of Autumn: The beginning of autumn.

Autumnal equinox: The equinox of day and night on this day.

Two solar terms!

Autumn equinox or the beginning of autumn, which is the real autumn? Don't be stupid.

The biggest difference between the autumnal equinox and the beginning of autumn is that they are different solar terms. The beginning of autumn is the coming of autumn, and the autumn equinox is the halfway of autumn.

The beginning of autumn is the traditional Chinese 24 solar terms, the morning and evening are cool and the noon is hot, the crops are ripe, the autumn equinox is astronomical, the sun shines directly on the equator, and the day and night time are equal.

In ancient times, the year was divided into four seasons, and each quarter was divided into three parts: Meng, Zhong and Ji, and the second month in the three autumns was called Mid-Autumn, so the Mid-Autumn Festival was also called "Mid-Autumn". The autumnal equinox is halfway through autumn. The beginning of autumn is the beginning of autumn.

The autumn equinox, the 16th of the 24 solar terms in the lunar calendar, is generally held on September 22 or 23 every year. The climate in the south begins with this solar term before autumn. First, the sun reaches 180 degrees of ecliptic longitude on this day and hits the earth's equator, so the day is divided into 24 hours and night, 12 hours each; The global phenomenon of infinite diurnal and nocturnal.

After the autumnal equinox, the polar night range near the North Pole becomes larger, and the polar day range near the South Pole increases.

The beginning of autumn is the 13th of the 24 solar terms, and the beginning of autumn occurs in August or 9 every year. "Autumn" means that the summer has gone to cool down, which means the beginning of autumn. At the beginning of autumn, the sycamore tree must begin to lose its leaves, so there is an idiom of "falling a leaf and knowing autumn".

From a literal point of view, the character "autumn" is composed of the word grass and fire, which means that the grain is ripe. The beginning of autumn is the first solar term of autumn, and autumn is a transitional season from hot to cool, and then from cool to cold.

To put it simply:

There are "four li" in a year - the beginning of spring, the beginning of summer, the beginning of autumn and the beginning of winter, which means the beginning of a season;

There are "two equinoxes" - spring equinoxes and autumn equinoxes, which can be understood as cutting the time of the year into two halves, and there is a saying that "the time is worth two equinoxes, and the day and night are equally divided". That is, every year on the day of the "spring equinox" or "autumn equinox", the day is as long as the night.

There are "two solstices" - summer solstice, "winter solstice". It can also be understood as cutting the time of the year in half. On the day of the "summer solstice" of the year, the day is the longest and the night is the shortest; On the day of the "winter solstice", the day is the shortest and the night is the longest.

The beginning of autumn is the beginning of autumn! The beginning of autumn means that summer is about to pass, autumn is coming, and the beginning of autumn is a transitional solar term when the weather changes from hot to cool, and then from cool to cold.

The beginning of autumn is also known as the autumn season, the general trend is that the weather gradually becomes cooler, due to the different climates throughout the country, the beginning of autumn time is also inconsistent, after the beginning of autumn, the early rice harvest in the central region of our country, late rice transplanting, the autumn crops enter an important period of growth and development, autumn means that the summer goes to cool, autumn begins, the ancients regard the beginning of autumn as an important moment at the turn of summer and autumn, and have always attached great importance to this solar term.

In ancient China, the beginning of autumn was divided into three phases: one waited for the cool breeze to arrive, the second waited for the white dew, and the third waited for the cold cicadas.
