On the day of winter solstice, the sun shines directly on the tropic of Capricorn, and on the second day of winter solstice, the sun will move northward. On that day in beginning of winter, the direct point of the sun was still moving southward day by day.

Beginning of winter and winter solstice have different climates.

As far as climate is concerned, beginning of winter was a symbol of China entering winter in ancient times. The winter solstice heralds the coldest time in winter, and it is also the first day of nine cold days. Traditionally, beginning of winter's status is not as high as the solstice in winter, and it is said that it is "as big as a year". The solstice of winter shows that the yin is the heaviest, but it also shows that the yang begins to be born, just like the dark moment before dawn. The winter solstice is also the start date of the calendar in China's traditional calendar (different from the beginning of the New Year).

In ancient times, solar terms were called "qi", and there were two qi in each month: the former was called "solar terms" and the latter was called "neutral qi". The monthly distribution of the 24 solar terms is shown in the following table, which is closely related to the arrangement of the lunar leap month. In the lunar calendar, beginning of spring is the first of the 24 solar terms. The names of the 24 solar terms are named according to the place pointed by Dougang and the natural climate and landscape at that time.

The so-called fighting means that the three stars of the Big Dipper, Kuixing, Xingxing and Yuxing, point to different directions and positions with the movement of celestial bodies, and the positions they refer to are the months they represent. For example, the first month is cloudy, the spoon refers to yin at dusk, refers to yin at midnight, and refers to yin during the day; February is the base, the Beidou at dusk refers to the base, the balance at midnight refers to the base, the chief refers to the base during the day, and so on.

The Significance of beginning of winter

At this time, the earth is located at declination-16 19', and the noon sun height in Beijing is only 33 47'. After beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon.

The significance of winter solstice

The solstice in winter, also known as the birth of the sun, is an important solar term in the China lunar calendar and a traditional festival of the Chinese nation. The winter solstice is commonly known as "Nine Days, Winter Festival", "Dragon Solstice Festival" and "Asian Year". As early as more than 2,500 years ago in the Spring and Autumn Period, China had observed the sun with the earth and determined the winter solstice, which was the earliest of the 24 solar terms.

It is worth noting that around the winter solstice, the earth is located near the perihelion, and its movement speed is slightly faster, which leads to that the time of the sun in the southern hemisphere is about 8 days shorter than that in the northern hemisphere, so the winter in the northern hemisphere is slightly shorter than that in summer.
