What are the characteristics of the beginning of spring in February? What are the characteristics of

In ancient China, the fifteen days of the beginning of spring were divided into three phases: "one is for the east wind to thaw, the second is for the stinging insects to start vibrating, and the third is for the fish to bear the ice", which means that the east wind warms and the earth begins to thaw. Five days after the beginning of spring, the dormant insects slowly wake up in the hole, and after another five days, the ice in the river begins to melt, and the fish begin to swim to the surface of the water.

In Chinese climatology, the beginning of spring is often defined as the beginning of spring when the average daily temperature of every five days is stable at more than 10, which is inconsistent with the meaning of the beginning of spring in the middle and lower reaches of the Yellow River. In late February, only southern China really entered spring. However, this division method is more realistic.

After the beginning of spring, the temperature rises, and the busy season of spring ploughing begins in most parts of the country. The days are getting longer and the temperature is warmer.

As the beginning of spring, the beginning of spring vividly reflects the natural characteristics of the beginning of spring. At the beginning of spring, people clearly feel that the days are longer, the sun is much warmer, and the temperature, sunshine, and precipitation tend to rise or increase. The agricultural proverb says it well:

When the rain arrives in spring, get up early and go to bed late. Although the spring is getting warmer, it is still necessary to protect against cold and ice because the weather is still unpredictable.

From February to the beginning of spring, people clearly feel that the days are longer and the sun is warmer. Temperatures, sunshine, and rainfall are often at the turning point of the year, tending to rise or increase.

At first warm, the earth thawed, and everything recovered.

The characteristics of the beginning of spring: the wind and the sun are warm, the birds are singing and the flowers are fragrant, and the spring plowing and sowing are sowing. After the beginning of spring, the days are getting longer, which means that the coldest period has basically passed, the weather has begun to gradually warm, and everything has gradually recovered.

The solar terms of the beginning of spring.

Around February 4 every year, the sun reaches 315 degrees of ecliptic longitude and passes the spring solar term. "The beginning of spring" is a solar term that heralds the change of seasons. This solar term was established as early as the end of the Warring States period (about 239 BC).

"Lichun" is the first of the 24 solar terms. In ancient times, the ancients believed that spring began to be called "Lichun", summer began to be called "Lixia", autumn began to be called "Liqiu", and winter began to be called "Lidong". Its agricultural significance is "spring planting, summer growth, autumn harvest, and winter storage".

Spring, summer, autumn and winter, led by spring. The six solar terms in spring, "the beginning of spring" comes first, marking the arrival of spring and the beginning of the four seasons, which is an ancient saying.

In fact, strictly speaking, it is the other way around: the Spring Festival is before the beginning of spring, and the time is after the beginning of spring. How is this different from the title?

The point is that on the lunar calendar, the beginning of spring is fixed. It is the rotation of the earth to the beginning of spring (in ancient times, it was believed that the sun reached the beginning of spring, but it was actually the same). And the Spring Festival date is based on the beginning of spring.

According to the calendar, the first day of the first month closest to the beginning of spring is the first day of the first month. We know that a synodic month has days. Therefore, the Spring Festival may be within 15 days before the beginning of spring (15 days may be full and only a little more than 14 days), and it can never be 16 days; It may also be within 15 days of the beginning of spring.

The beginning of spring is one of the 24 solar terms of the lunar calendar, in a sense, the 24 solar terms are basically stable and unchanged on the solar calendar, a song slips smoothly "every 621 in the first half of the year, and 823 in the second half of the year, the date is generally fixed, and sometimes it is one or two days apart." In other words, the 24 solar terms are determined by the movement of the sun.

The Spring Festival is determined by the operation of the moon, the solar calendar is generally 365 days a year, the lunar calendar is 360 days a year, in order to catch up with the difference, a leap month is added every few years, that is to say, the lunar calendar has thirteen moons for a complete year, so as to balance the difference between yin and yang, sometimes the beginning of spring before the Spring Festival, but most of the Spring Festival after the beginning of spring, but when the Spring Festival before and after the beginning of spring but most of them are February 4, the Spring Festival is not according to the solar calendar, because it is the lunar calendar, so sometimes the beginning of spring is a long time after the Spring Festival.

According to the calendar. The day of the beginning of spring is fixed relative to the solar calendar, and the error around February 5 is only 1 day. And the Spring Festival is the first day of the first lunar month.

According to the lunar calendar, the moon phase must be "Shuo" on the first day of the lunar calendar. There is a day between the two "Shuo". It is stipulated that the "Shuo" near the beginning of spring is the first month.

Therefore, the beginning of spring is almost in the middle of the two new days. The Spring Festival is far away from the beginning of spring; The beginning of spring is very close to the new day (sometimes it coincides), and the Spring Festival is close to the beginning of spring. Even sometimes on the same day.

February is mid-spring. February is the second month of spring, and because it is in the "middle" of spring, it is called "mid-spring". There are many other names for February, such as Flower Moon, Liyue, Apricot Moon, Zhongyue, Hearty Moon, Zhongyang, Jiazhong, Dazhuang, Maoyue, etc.

February is the season of spring flowers, which is why people have come up with so many intoxicating names for February (the latter three are from the rhythm, hexagram and earthly branches, respectively).
