What does the sentence "February is sunny and green, March is sunny and barren" mean?

This year, Tomb-Sweeping Day Gregorian calendar falls on April 4th and lunar calendar falls on February 23rd. According to the rural words, this year's lunar calendar passed Tomb-Sweeping Day in February. As the saying goes in rural areas, "February is sunny, and March is short of grass". Why does it have a greater impact on agricultural production when people visit Tomb-Sweeping Day in February than Tomb-Sweeping Day in March?

1. What's the difference between the Gregorian calendar and the Lunar calendar? To understand the meaning of the above rural words, we must first understand the difference between the solar calendar and the lunar calendar. According to the countryside, there are 24 solar terms in a year, and Tomb-Sweeping Day is one of them. The twenty-four solar terms are recorded according to the ecliptic of the sun, which is what people call auspicious days. It is the track of the sun running for one year with the earth as the reference object, that is, 24 solar terms. From the vernal equinox, every circle is 15 degrees.

The Gregorian calendar is the time for the earth to go around the sun once, that is, 365 days, which is based on the sun. The lunar calendar is a combination of the solar calendar and the lunar calendar, which is based on the orbit of the moon around the earth. The time of the lunar calendar is only 29 and a half days per month and only 354 days per year, so the solar calendar is 1 1 day more than the Gregorian calendar, and after three years, it is 65,438 days more. There is a saying in the lunar calendar called leap moon. If there is a leap month in the lunar calendar, the solar calendar has 13 months. This leap month is used to make up the time difference between the solar calendar and the lunar calendar, that is, the difference between the solar calendar and the lunar calendar.

2. What's the difference between the solar calendar and the lunar calendar in Tomb-Sweeping Day every year? According to the solar calendar, the time in Tomb-Sweeping Day is basically fixed, that is, from April 4th to April 6th every year. But the lunar calendar is very different, sometimes it is February and sometimes it is March. This year is February of the lunar calendar, which is the Tomb-Sweeping Day in Tomb-Sweeping Day.

In March and February, the sky is clear and green, and the grass is not born in March. How to understand it? Knowing the above two aspects, it is much easier to understand this rural proverb. If Tomb-Sweeping Day is in February of the lunar calendar, then beginning of spring must be before the Spring Festival. If beginning of spring is after the Spring Festival, then Tomb-Sweeping Day is in March of the lunar calendar.

Before the Spring Festival in beginning of spring, the temperature rises rapidly in spring and the cold time in winter is short. Grass seeds and eggs buried in the soil will not freeze to death. After beginning of spring, when the weather gets warmer, weeds will grow prematurely, so the weeds in the field are green.

If Tomb-Sweeping Day is in the third month of the lunar calendar, then beginning of spring is after the Spring Festival, which means that the winter is longer, and the grass seeds and eggs buried in the soil are frozen to death. After spring, weeds will grow slowly, so when you look at the fields, you can't see the green of weeds, so Qingming grass was not born in March, that's how it came from.

There is a great difference between Tomb-Sweeping Day in February and Tomb-Sweeping Day in March, especially for agricultural production, but through these rural proverbs, we can understand a problem, that is, the difference between the lunar calendar and the solar calendar, why Tomb-Sweeping Day in February and Tomb-Sweeping Day in March, what is the focus, and what is the impact on agricultural production? Do you think my understanding of this sentence is correct? Welcome to exchange and discuss in the comment area.

Generally speaking, there are 24 solar terms in a year, the time in the solar calendar is basically fixed every year, and the time in the lunar calendar changes greatly every year.

Tomb-Sweeping Day falls on April 5th or 6th of the Gregorian calendar, and the beginning of the third month of the lunar calendar occurs all year round. However, if there is a leap month in the lunar calendar, Tomb-Sweeping Day may be in early February of the lunar calendar. At this time, February in the lunar calendar is April in the solar calendar, and March in the solar calendar is May in the solar calendar, which is much warmer than February and March in normal years. So Qingming is in February, the fields are green, Qingming is in March, the earth is not rejuvenated, and the fields don't grow grass.

The ancient peasants' induction and summary of agricultural proverbs and common sayings all depend on long-term production and life practice, which is closely related to agricultural production and life.

Another year is clear, birds and flowers are fragrant, things are transformed, and the spring rain is like silk, so I don't feel sad!

202 1 here comes Tomb-Sweeping Day. This year's Tomb-Sweeping Day is on April 4th of Gregorian calendar and February 23rd of lunar calendar. The sun moves to the longitude of the Yellow River 15 degrees, and the Big Dipper moves to the second position.

Tomb-Sweeping Day is one of the twenty-four solar terms in China, and it is also the time for the transition of mid-spring and late spring. At this time, spring and Jingming spit out the old and absorb the new, full of spring, full of flowers and vitality, which is a good time to step on the spring.

Tomb-Sweeping Day's biggest traditional custom in China is to sweep graves. Is to worship ancestors, or go to the grave to mourn ancestors. Mourning day, drizzle like tears; Pedestrians on the road want to die. Ask local people where to buy wine? The shepherd boy just laughed and didn't answer Xingshan Village. This poem describes three customs in Tomb-Sweeping Day.

According to the Gregorian calendar, the date in Tomb-Sweeping Day is mainly one of the three days from April 4th to April 6th, but according to the China lunar calendar, it is uncertain, either in February or March.

Here, everyone should understand what is the solar calendar and what is the lunar calendar. In this way, we can determine why the days in Tomb-Sweeping Day are fixed in the solar calendar instead of the lunar calendar.

Tomb-Sweeping Day is formulated according to the laws of the sun's movement, which is also a major basis for the formulation of the 24 solar terms. The solar calendar is based on the rotation law of the sun. Lunar calendar is a unique method to mark the year, day and time in China, which is mainly based on the rise and fall of the moon, that is, the law of the moon's orbit around the earth. Therefore, it is uncertain whether the date calculated by Tomb-Sweeping Day according to the China lunar calendar is in February or March of the lunar calendar.

As the saying goes in the countryside, "February is sunny and green, and March is sunny and barren!" This proverb means that in Tomb-Sweeping Day in February of the lunar calendar, when Tomb-Sweeping Day arrived, the vegetation had sprouted, and the earth was covered with a lush blue, full of vitality. That is, spring comes earlier.

For example, spring came earlier this year. Beginning of spring was on the 22nd day of the twelfth lunar month last year, and this year's Tomb-Sweeping Day is on the 23rd day of the second lunar month. The land is lush, and flowers are everywhere.

Once in Tomb-Sweeping Day, in the third month of the lunar calendar, Tomb-Sweeping Day arrived, but the vegetation hasn't grown yet, that is, the weather is still cold and it hasn't sprouted yet. The temperature rises relatively slowly. But it's not that the grass hasn't grown yet, but that the grass has grown smaller, and the earth can't see the lush appearance, and it's warm and cold at first.

This proverb is just another proverb in the countryside: "No flowers are seen in February, but flowers grow old in March!" " This means that if Tomb-Sweeping Day is in February of the lunar calendar, Tomb-Sweeping Day will never see flowers again. If Tomb-Sweeping Day arrives in Tomb-Sweeping Day in the third month of the lunar calendar, the flowers will almost fade. After all, Qingming has come, the sun has moved to the northern hemisphere, and the temperature is rising.

Generally speaking, this year's Tomb-Sweeping Day is a sea of budding flowers and plants, and the earth is now green. Mainly this year is a year without spring, that is, a year of widowhood. beginning of spring is in the twelfth month before the Spring Festival.

Of course, this year's La Nina phenomenon is more serious, which will make more rain in the north, which is more conducive to the growth of vegetation and the recovery of everything. The temperature rises faster, a spring rain, a warmth.

But we must prevent the phenomenon of late spring cold this year, because according to the forecast of meteorologists, the phenomenon of late spring cold this year is more serious. Especially cold air, from time to time south, even in northern China, there have been rain and snow in the last two days, falling frequently.

Tomb-Sweeping Day, together with China's Spring Festival, Mid-Autumn Festival and Dragon Boat Festival, are called the four traditional festivals in China. Almost all of these major festivals are directly related to ancestor worship, reunion or ancestor worship.

This year's Tomb-Sweeping Day is different from previous years. Because of the influence of COVID-19, some migrant workers didn't go home for the Spring Festival this year, and their holidays were pushed to Tomb-Sweeping Day. Therefore, the passenger flow in Tomb-Sweeping Day this year is relatively higher than in previous years, which is one of the reasons why Tomb-Sweeping Day has a three-day holiday this year.

The same agricultural proverbs as "Tomb-Sweeping Day is green in February, and the grass is barren in March" include "Flowers don't bloom in March, flowers bloom in February" and "Tomb-Sweeping Day is not in front in February, and Tomb-Sweeping Day is not behind in March". Many people are racking their brains to explain these problems. In fact, as an agricultural proverb, due to its geographical and historical limitations, it is difficult to interpret it comprehensively and correctly. For example, Tomb-Sweeping Day planted melons and beans before and after. Henan can, Hebei can't, and the northeast can't, because in spring, Henan is full of flowers, Hebei is warm and cold, and the northeast is still frozen.

Many agricultural proverbs are the products of ancient farming civilization.

It can even be said that it is the product of farming civilization in the Central Plains, so the scientific nature of agricultural proverbs has great limitations, and the interpretation of these agricultural proverbs must be based on regional positioning.

The agricultural proverb "February is fine, March is barren" is based on the lunar calendar, and the festival days of the lunar calendar are very uncertain, so it is unscientific and unconvincing to say that the date of the lunar calendar cannot explain the exact location of 4: 08.

Whether the land is green or not depends on the solar terms, not February or March. The solar terms are based on the position of the ecliptic of the sun. Tomb-Sweeping Day is the first solar term in which the equatorial line of the sun directly returns to the north, and the azimuth of the ecliptic is 15 degrees. As the northern hemisphere slowly enters summer, the temperature will gradually rise, and the summer solstice solar terms will reach the Tropic of Cancer, then return to the Tropic of Cancer, and so on. Because the Gregorian calendar is based on the revolution of the earth around the sun, the Gregorian calendar can explain the position of the sun and the climate change most accurately.

In rural areas, it is often said that this winter is big, that is to say, this winter is long, because of the wrong concept caused by leap month. Jumping on the moon will cause the solar terms to move forward. For example, last year (leap April in 2020), the start time of the Winter Festival was half a month earlier than that of 20 19, and the Spring Festival was delayed by more than half a month, thus creating the illusion that winter is big. In fact, winter is still so big.

In leap February, 2023, Tomb-Sweeping Day was on the fifteenth day of leap, and decided to be "Wan Li with clear skies in February". If it's not a leap month, Tomb-Sweeping Day will be on March 14th, and "March will not last long" is also a joke.

Therefore, many agricultural proverbs are unscientific and narrow-minded, including the above words "Tomb-Sweeping Day can't open in March, Tomb-Sweeping Day can't open in February" and "Tomb-Sweeping Day is not in front in February, and Tomb-Sweeping Day is not behind in March". Many people take it for granted and make some meaningless interpretations.

The February and March mentioned here are both lunar calendar. Because there is a leap month in the uncertain time of the lunar calendar, that is to say, some years have thirteen months, so sometimes Wang Jianqing doesn't turn green until February and March. In fact, flowers bloom and fall basically according to the lunar calendar, so it is said that in the Qingming period (also on April 4 of the solar calendar), flowers bloom in February of the lunar calendar, not in March.

For example, 202 1, Tomb-Sweeping Day is on April 4th, and February 23rd of the lunar calendar. Recently, spring has blossomed everywhere. April 5, 2022, Tomb-Sweeping Day, March 6, the lunar calendar. At that time, I'm afraid the buds have already appeared and the spring branches have just sprouted. On April 5th, 2023, Tomb-Sweeping Day will leap into February 15. If there is no leap in February, the difference between the solar calendar and the lunar calendar is only 20 days. By the second half of 2024, the solar calendar and the lunar calendar will be almost the same day. This is why there is a leap month, that is, there is no leap month, and the flowering time of1February is wrong. Maybe Osmanthus fragrans will bloom in October or in January.

As the saying goes, "February is fine, March is short of grass", which is determined by the time difference between the lunar calendar and the solar calendar. The closer the leap year is, the later the flowers bloom, and vice versa.

It is a fairly stable and common thing when solar terms "cross", but the vast rural areas in China still follow the lunar calendar, which leads to a unique question: When does a solar term cross in the lunar calendar? This question is not clear. I've posted 10 or 20 posts in these three years alone.

It was not a big deal to "pay wages" one day, but once someone made a big fuss about it, it was linked to the year and personnel. To put it mildly, it is a rumor to mislead people. So it's clear.

The road to Jane, needless to say. This matter originally only needed one sentence: solar terms are things in the solar calendar, and the date of solar terms is subject to the solar calendar. It's that simple.

The problem is that there are still people in rural areas who like to talk about things with the imperial calendar, so they are entangled. This is about the "urgent March" of the two calendars. There are 365 days in the solar calendar and 354 days in the lunar calendar, so there is no way to "align". All over the world, mainly in the Middle East and Asia, have long found ways to avoid the two calendars being too staggered. At present, only a few places are still using two calendars to live their own lives at the same time. I don't care if you are in the first month or June. The way to align in most places is to "set a leap". In China, about two thousand years ago, there was a method of "seven leaps in nineteen years".

As soon as the leap is set, the positions of all solar terms in the lunar calendar will run everywhere, and there can be a difference of one month before and after-running around in a range is better than running in winter and summer. But people who don't understand are confused, and people who are good at showing off look for opportunities to talk. So there are many days to talk about all the year round: single spring, no spring, double spring, spring in a year ... and it can also be linked to the year. Once it is linked to the year, it can be linked to people: starving pigs and dogs, "widowed year" and "many graves" .....

To put it bluntly, nothing. It's just that some Zhuge Liang is spreading lies to mislead the people.
