Who invented the "twenty-four solar terms" in the lunar calendar? Who invented leap year?

The twenty-four solar terms of the lunar calendar were invented by Zhuan Xu. Some people may not know the word Zhuan Xu. Turn means round head and fat brain, and turn means jewelry. Together, they are all Dai Yu's people.

Zhuan Xu (zhuān xū), an ancient tribal leader in China, is one of the "Five Emperors". His surname is Ji, Ming Lai, the grandson of the Yellow Emperor and the son of Changyi.

Zhuan Xu was born in Ruoshui, living in poverty, and later became a fief in Levin. Later proclaimed himself emperor. Abolish the system of bird officials and establish the system of five senses. Shao Hao's gossip calendar was abolished, and a more scientific and practical Zhuan Xu calendar was established according to the needs of agricultural production and life at that time.

The Zhuan Xu calendar began in Meng Chun, and the first day of the first month was beginning of spring. A year is divided into1February, with 30 days per month and 36 days per year1February. A year is divided into four seasons: spring, summer, autumn and winter. Each season is divided into three solar terms: Meng, Zhong and Ji. There are twelve solar terms in the four seasons. This is the embryonic form and foundation of the 24 solar terms.

The calendar in the early Han Dynasty basically followed the Zhuan Xu calendar, the Zhuan Xu calendar was a quarter calendar, and the length of the tropical year was 365 days and 1/4 days, and 19 years was 7 leap. During the reign of Emperor Wu of the Han Dynasty, Sima Qian and others were ordered to create the Han Calendar, and Deng Ping created the 8 1 point calendar, which was called taichu calendar in history.

At this time, the "twenty-four solar terms" were basically established. Liu An's Huai Nan Zi? Determining the standard of 24 solar terms in astronomical training is the running direction of Beidou. The operation of Beidou cooperates with the 28 th Academy to form a scientific calendar and astronomical system.

In 20 16, the "24 solar terms" declared by China was included in UNESCO's Representative List of Intangible Cultural Heritage of Humanity.

Leap year was founded in the ancient Emperor Yao, and the founder of accurate algorithm was Zu Chongzhi. The concept of leap year is recorded in history, which first appeared in Yu Shu Yaodian, "Set the leap month at four o'clock, and it will be an adult ceremony." Kong Chuan said, "When you are one year old, you will be twelve days, and before you are three years old, you will leap." It shows that there has been a more accurate method of leap moon in ancient times.

In ancient times, the calculation method of seven leap years in nineteen years in Chapter One was always used. In other words, seven of the nineteen years are thirteen months. This algorithm has been used for more than one thousand years. But this algorithm is not scientific, accurate and accurate enough. Zu Chongzhi put forward a new algorithm of 39 1 year 144 leap according to Yuan Jia calendar and ancient calendar and his own observation and experimental calculation.

Moreover, the calculation and use of "precession" and "intersection month" are put forward for the first time. Finally, the latest calendar, Daming Calendar, was produced.

According to legend, the twenty-four solar terms were invented by Zhuan Xu, the grandson of the Yellow Emperor, and the leap year was decided by Emperor Yao. The legend is not necessarily true. The ancients of our country concentrated all the good things on celebrities, which was easy to spread. The invention of the twenty-four solar terms was not completed in one day, nor should it be an individual achievement, but the crystallization of collective wisdom and the result of several generations' observation and practical research. The accurate calculation of leap year should be done by Zu Chong, an ancient scientist in China. There is no doubt that the twenty-four solar terms were invented by the working people in ancient China.

Since the birth of mankind, they have formed an indissoluble bond with the years. Everything is born with the years, and everything dies with the years. The history of calendar is also the history of human change. The scientific calendar shows that time is not mysterious. Leap at the right time, do things at the right time, do things at the right time, and follow the heaven. Ancient Chinese people observed astronomy and made calendars long ago, which can be traced back to the era of the Yellow Emperor. There are many legends about astronomical calendars, solar terms and leap years, and they are still myths, which can be believed but not completely believed. The solar calendar is from phenological calendar to astronomical calendar. Our country's calendar has experienced many changes and controversies. Among the pre-Qin calendars, there are hundreds of Xia, Shang and Zhou calendars, including the seasonal calendar and the ancient 60 thousand calendar. From the Han Dynasty to the Ming and Qing Dynasties, there were taichu calendar, Dayan, Twelve-Qi, Timing and Chongzhen calendars. Among the calendar disputes, there are disputes over taichu calendar, Daming calendar, imperial calendar, Dayan calendar, Chongzhen calendar and current constitutional calendar.

The origin of the twenty-four solar terms, I am sure, began in the Spring and Autumn Period and was established in the Qin and Han Dynasties. It should not be just an invention of one person, but a summary of collective experience and wisdom. The leap year calculation is more accurate, thanks to Zu Chongzhi's correctness. The 24 solar terms are gradually improved, first half, then four, and so on. It was first determined by Tugui's solar shadow method. Today, the oldest "Zhougong Station" is still preserved in Jiao Da, Songshan, Henan, which is the best evidence.

The 24 solar terms are not the invention of someone, but the crystallization of the historical experience and wisdom of our working people, which should be said to be China's intangible cultural heritage. Twenty-four solar terms originated in the Yellow River Basin. After continuous improvement and perfection, in 104 BC, Deng Ping formulated the taichu calendar, and formally set 24 solar terms in the calendar.

Similarly, leap year was not invented by someone, but was set up to make up for the time difference between the number of days in a year caused by man-made calendar regulations and the actual period of revolution of the earth. The year to make up for the time difference is leap year.

The twenty-four solar terms and leap year are both part of the ancient calendar of our country, which is what we usually call the lunar calendar.

Who invented the "twenty-four solar terms" in the lunar calendar? Who invented leap year?

Twenty-four solar terms and leap month were gradually founded by the working people in ancient China in the practice of agricultural production. No one has studied and invented them, but they are the crystallization of the wisdom of the ancient working people in China.

The 24 Solar Terms

At the earliest time, the year was divided into spring and autumn, and in the Zhou Dynasty, it was further divided into spring, summer, autumn and winter. About 2500 years ago, during the Spring and Autumn Period and the Warring States Period, there were four solar terms: the second solstice (winter solstice, summer solstice) and the second vernal equinox (vernal equinox, autumn equinox). Later, after continuous supplement and improvement, the Western Han Dynasty had 24 solar terms.

Twenty-four solar terms play an important role in China calendar. According to the solar calendar, the 24 solar terms are arranged as follows:

February: beginning of spring, it rains;

March: fright, vernal equinox;

April: Qingming, Grain Rain;

May: long summer, small full;

June: awn seeds, summer solstice;

July: Little Summer, Big Department;

August: beginning of autumn, long summer;

September: white dew, autumn equinox;

October: cold dew, first frost;

1 1 month: xiaoxue, beginning of winter;

1February: heavy snow, winter solstice;

January: slight cold, severe cold.

The 24 solar terms are closely related to agricultural production. As can be seen from the names of the 24 solar terms:

The word "Li" written by beginning of spring, Chang Xia, beginning of autumn and beginning of winter indicates the coming of spring, summer, autumn and winter.

The word "solstice" in summer and winter indicates that summer and winter have arrived;

The word "fen" in the vernal equinox and the autumnal equinox means equal distribution. These two days are equal day and night, just in the middle of summer solstice and winter solstice;

Rain means it begins to rain, and the rain gradually increases;

Sting means that the weather gets warmer, and spring thunder begins to sound, awakening insects hibernating underground;

Qingming means sunny weather and everything breeds;

Grain Rain marks the increase of rainfall and the vigorous growth of grain;

Xiaoman said that summer crops such as wheat are about to mature;

The awn seed is the mature period of awned crops such as wheat, and it is also the rush maturity period of late-maturing crops.

Slight summer heat and great summer heat are the hottest seasons in a year, and the so-called "three volts" is this period;

The word "early" in the department means termination, indicating that the summer day has passed and the temperature has begun to drop;

White dew means that the temperature drops and dew appears;

Cold dew refers to the cold weather and cold dew;

The first frost, began to frost;

Light snow, heavy snow, it begins to snow until the snow forms;

Slight cold and severe cold are the coldest seasons in a year, and people usually use "nine" to indicate the degree of cold in this period.

In order to facilitate memory, the masses also made it into songs and spread it widely:

Spring rain shakes the valley in spring, summer is full of mountains and summer is hot, autumn dew is cold and frost, winter snow is cold and cold.

Leap moon-the leap moon in the lunar calendar

The ancient calendar in China was not a pure lunar calendar, but a yin-yang calendar.

In the lunar calendar, the normal years are 12 months, 6 big months, 30 days each month, 6 small months, 29 days each month, and 354.355 days throughout the year. The length of the first month of the lunar calendar is 29.5306 days, and the difference between the number of days in the whole year and the solar year is about 10 and 2 1 day. So we should make a leap, that is, after the middle of the Spring and Autumn Period, three years and one month, five years and two months, 19 years and seven months. Every leap year, one month is called "leap month", and the next month is called "leap month".

The ancients attached great importance to setting leap, which can make the average length of the calendar year equal to about one solar year, which is roughly consistent with the natural season. Therefore, Shangshu Yaodian said that "the leap month is fixed at four o'clock".

According to the existing literature, the leap month was set in the Yin and Zhou Dynasties, usually at the end of the year, called "March". At that time, leap was not customized, and sometimes there were two months in a year, so there would be "April" in the Spring and Autumn Period. From the Qin Dynasty to the early Han Dynasty, after September, the twilight had set in the west, which was called "the last September". For example, Biography of Historical Records of Lv Hou said: "After September, twilight has arrived in Chang 'an. In the early generation, October was the beginning of the year and September was the end of the year, so the leap month was placed at the end of the year. There were also intermediate leaps in ancient times, such as March and June. When you jump without jumping, it is called "missing jump"

Thanks for reading! I am "when culture has wings"!

The twenty-four solar terms in ancient times are the crystallization of China people's wisdom, which guides the traditional agricultural production and daily life. In the field of international meteorology, the twenty-four solar terms are known as "the fifth invention of China" and were listed in the representative catalogue of "Intangible Cultural Heritage of Humanity" in 20 16.

"The statement of' the fifth great invention' has scientific basis. Because the' 24 solar terms' are not only the intangible cultural heritage of mankind, but also the precious scientific heritage created by the ancestors of the Chinese nation in thousands of years of agricultural production practice. From the climatological point of view, the twenty-four solar terms are the laws of seasonal and climatic changes gradually recognized by the people of China in the long-term production practice, which embodies the scientific attitude and correct views and methods of China people towards nature.

"Twenty-four solar terms" originated in the Yellow River valley, and divided a year into beginning of spring, Changchun, beginning of autumn and beginning of winter. To reflect the changes of season, temperature, rainfall and phenology. This reflects the simple cognition of China ancients on climate. During the farming period, farmers in China always depend on the "24 solar terms" to arrange their life and production. This scientific understanding then spread to overseas continents, affecting the whole world.

"From the point of view of modern meteorology, the formation of climate is mainly influenced by solar radiation, earth movement and atmospheric circulation. Although the' Twenty-four solar terms' are not explained from these angles, they also reflect the ancient people's understanding of China's climate from natural phenomena, and objectively reflect the unique climate characteristics of China, such as distinct seasons.

The book Summer is the earliest symbolic text to record the changes of solar terms and phenology in China, and the recorded contents and observation results are the basis for the formation of the "Twenty-four solar terms" later. The ancients regarded five days as the sky, three times as the sky, six times as the sky, four times as the age, and seventy-two times as the sky. The essence of climate is the mutual movement between the earth and the sun, and it is the organic combination of phenology and meteorology in the process of agricultural production practice.

In China, the system of "24 solar terms" has been gradually improved. As early as the Spring and Autumn Period and the Warring States Period, China was able to measure the length of the shadow of the sun at noon with a soil gauge (a pole was erected on the plane); At the end of the Warring States Period, Lu's Spring and Autumn Annals clearly mentioned four solar terms: winter, summer, vernal equinox and autumnal equinox. In a year, the shortest day of the noon soil return shadow is the summer solstice, the longest day is the winter solstice, and the shadow with moderate length is the vernal equinox or autumn equinox. There is a complete record of "Twenty-four solar terms" in Huainanzi edited by Liu An in the Western Han Dynasty. This paper introduces the calculation method and related contents of solar terms in detail, and discusses the generation of natural phenomena such as the sun, the moon, the wind, thunder and lightning and their influence on human and social life order and agricultural production.

It is particularly noteworthy that the Taosi Ancient Observatory was formed at the end of primitive society in 2 100 BC, nearly 500 years earlier than the Stonehenge Observatory recognized in the world (BC 1680). With the discovery of the ancient observatory of Taosi Temple in Xiangfen, Shanxi Province, the records in Shangshu Yaodian are further confirmed, indicating that China people observed meteorology 500 years earlier than the west.

So why design a leap year?

According to research, it was the first time that the Egyptian Empire added a similar concept of "leap year" to the calendar of 365 days a year. They want to use the solar calendar and make sure that the calendar is not out of touch with the seasons.

Later, Julius Caesar of the Roman Republic created a calendar of 12 months and 365 days a year according to the Egyptian calendar. Prior to this, people mainly used a calendar of 355 days a year, with one month inserted every two years. Although this calendar prevailed for some time, with the research finding that a year is actually about 365.24 days, Caesar invented the method of revising leap years every four years, so he was called "the father of leap years".

Under the Gregorian calendar and leap year system, the calendars of most countries in the modern world are in sync with the seasonal cycle.

For centuries, human beings have been trying to synchronize civil calendars, religious calendars and agricultural calendars with the solar year. Finally, people solved this problem by adding "leap year". However, this is only temporary, and this problem will appear again in 3300 years.

Leap year comes as scheduled: this Saturday, that is, February 29, is leap day. This strange phenomenon in the calendar occurs (almost) every four years.

For centuries, people have been trying to synchronize calendars with natural years, but unfortunately, it backfired and caused a lot of confusion. It was not until the leap year appeared that the lost time was made up.

This is because the earth's revolution around the sun is not 365 days, but 365+09 days.

Tropical year-the actual number of days of one revolution of the earth (approximate value)

But who wants to celebrate the New Year on 365+09 days?

So we removed the odd part and unified the year into 365 days. But what's the score? 0.242 19 days is about 5.8 hours. In other words, we lose 5.8 hours a year.

Where has all the time gone? This is the answer.

However, people have long understood that time equals money. So in 45 AD, the Roman dictator Julius Caesar came up with a solution to the loss of 5.8 hours a year:

"Let's just spend three years, not counting the extra 5.8 hours. In the fourth year, we added up these useless time and arranged a whole day in February. "

In this way, leap year and leap month appeared!

Although Caesar came up with this idea by patting his head, don't say that he made sense.

If we always ignore less than 5.8 hours a year, after 100 years, there will be a difference of 25 days between our "Gregorian year" and "real year" (or tropical year)! In other words, every century we will be less than nearly 1 month.

Ancient calendar experts in China have always used 19 years as the unit of leap year calculation, which is called "one chapter", and each chapter has seven leap years. In other words, after nineteen years, seven years is thirteen months. This leap method has been used for more than 1000 years, but it is not thorough and accurate enough.

In 4 12 A.D., Zhao Zuo of Beiliang wrote Yuan Li, which broke the limitation of the annual chapter and stipulated that 22 1 leap month should be inserted in the middle of 600 years. Unfortunately, Zhao Xu's reform did not attract people's attention at that time. For example, when He Chengtian, a famous calendar mathematician, made Li Yuanjia in 443 AD, he still used the ancient method of seven jumps in nineteen years.

Zu Chongzhi used Zhao Kuo's advanced theory for reference, and combined with his own observation, he thought that there were too many leap numbers of seven leap years in nineteen years, one day less every two hundred years, while the leap numbers of two hundred and twenty-one leap years in Zhao Kuo were too sparse and inaccurate. So he proposed a new leap method of 39 1 year 144 leaps, which was the most accurate at that time.

In addition to reforming the leap method, Zu Chongzhi's other great achievement in calendar research is the first application of "precession".

Zu Chongzhi's third contribution to calendar research is that he can find out the days in the calendar, which is usually called "crossing the moon".

Based on the above research results, Zu Chongzhi finally succeeded in making the most scientific and progressive calendar at that time-Daming Calendar. This is the genius of Zu Chongzhi's scientific research and his most outstanding contribution to the astronomical calendar.

2020 is really a special year, with leap years and leap months. I hope everything will get better in this particularly long year.

The "twenty-four solar terms" of the lunar calendar is a unique seasonal division in China, which played a key guiding role in agricultural production in ancient China.

Why do China have 24 solar terms? Chinese civilization is an agricultural civilization, and the sowing, field management and harvesting of crops must not go against the farming season, that is, they must be carried out at the right time to have a good harvest. So why didn't other ancient civilizations in the world, which were dominated by agriculture, produce twenty-four solar terms?

This is because the climate of ancient civilizations such as ancient Egypt, ancient Babylon and ancient India is warm and humid, and there is no severe cold in winter, so the planting time of crops will not be too limited. Unlike China, China has a continental climate with cold winters. Therefore, spring sowing and autumn harvest must be carried out in strict accordance with the solar terms, otherwise the hard work of one year will be in vain.

However, such an important invention is not the work of one person. It was slowly summed up by the ancient ancestors of China after a long time and practice. Like wooden houses and pottery making, it is also the product of collective wisdom.

How are the 24 solar terms divided? China used the lunar calendar in ancient times, but the 24 solar terms followed the solar calendar. For example, the annual vernal equinox and autumnal equinox are fixed dates. Why? This is because the lunar calendar has little influence on agricultural production, and only according to the solar calendar, that is, the height of the sun, can agricultural production be guided.

So the ancients divided the year in the solar calendar into 24 equal parts on average, and each equal part was defined as a solar term. The ancients didn't know that the earth revolves around the sun today, so they divided the solar terms according to the orientation change of the Big Dipper.

The specific names of the 24 solar terms are as follows:

Beginning of spring, rain, fright, vernal equinox.

Qingming, Grain Rain, Changxia, Xiaoman.

Ear seed, summer solstice, slight summer heat, great summer heat

Beginning of autumn, Chushu, Bailu, Autumnal Equinox.

Cold dew, first frost, beginning of winter, light snow.

Heavy snow, winter solstice, slight cold, severe cold

When the ancients carried out agricultural production according to the solar terms, they summed up many tricks, such as "sowing in Qingming, transplanting rice in Grain Rain", "planting rice with a shovel, not harvesting cotton on the summer solstice" and "ploughing the land in a thousand years, turning the land in the autumn equinox", which formed valuable experiences and passed down from generation to generation in ancient times.

How did leap year come about? First of all, leap year was not invented by one person. Even if some people think it is necessary to stipulate leap year in history, it has long been lost in the torrent of history.

The leap year in the modern sense is to make up for the error of the solar calendar. Because the period of the earth's revolution around the sun is 365 days at 5: 48: 46, which is 365 days in a year, the extra time every four years adds up to about one day, so every four years, one more day is added in this year.

However, leap years in ancient China did not have such regulations.

In ancient China, according to the lunar calendar, there were 12 months every year, and each month had 30 days, which was more than 5 days different from the solar calendar, so one month was added every 2 to 4 years, and the added month was called leap month. The leap month is added to the year, which needs to be judged by referring to the 24 solar terms. A year with a leap month is called a leap year.

Similarly, the leap year in ancient China was not attributed to anyone, but was based on the long-term observation of ordinary people and then decided by the state.

The legend of the origin of the lunar calendar can be traced back to the Yellow Dynasty to the Xia Dynasty. According to the orbit of the sun, a year is divided into 24 solar terms, about 366 days, also known as the summer calendar, the dry calendar, the lunar calendar and the solar calendar. . In the Spring and Autumn Period, based on the orbit of the moon, the new moon looks like January, with twelve months in a year, which are called lunar calendar, lunar calendar and lunar calendar respectively. Month and day are calculated by numbers (year or year number), and a year is about 354 days. .

China calendar is actually a combination of solar calendar and lunar calendar. Every lunar month with only a few lifeless days must be repeated, which is called Runyue. A year with Runyue has about 383 days. (The calendar in China is called Runyue, not Runnian. )

The solar terms in A.D. and the Gregorian calendar (Gregorian calendar, new calendar) are based on the orbit of the sun, so the duration is the closest. China was the western calendar introduced after the Revolution of 1911, and it was not until the founding of People's Republic of China (PRC) that the name of the Republic of China was stopped. They are all used with the China lunar calendar.

Twenty-four solar terms were summed up by the ancient people's practice of "harmony between heaven and earth" and "moving light and positioning, treating people with integrity" (note: Huangdi Neijing), combined with long-term production, astronomy and meteorology.

The twenty-four solar terms represent the position (ecliptic) that the earth reaches when it orbits the sun. The circumference of the ecliptic is 360 degrees. Every year on March 2 1 day in the solar calendar, the sun passes through the vernal equinox, and the longitude of the ecliptic is 0. After that, the longitude will gradually increase along the ecliptic, and one lap will be one year.

Every 15 degrees is a solar term, so there are two solar terms every month, December 24 solar terms, and six solar terms every season. Ancient solar terms were called "Qi", and each month contained two Qi, the former was called "Solar Term" and the latter was called "Zhong Qi".

The twenty-four solar terms accurately point out the climate changes throughout the year and directly serve agriculture, astronomy, geography and medical care, which is the most distinctive feature of our calendar and is not found in other countries in the world.

Twenty-four solar term song

The spring rain surprised the spring and the valley.

Summer is full, summer is full, and summer is hot.

Autumn dew and autumn frost.

It snows in winter, it snows in winter, and it's a little cold in winter.

There are no changes in two festivals every month.

A day or two at most.

From 62 1 in the first half of the year

Come in the second half.

The date of the twenty-four solar terms of the lunar calendar is postponed month by month, so in some lunar months, the gas falls at the end of the month, and it will be out of gas next month. Generally, every two years or so, there will be a month without neutral atmosphere, which coincides with the year when leap months need to be added. There is a saying that "jump at both ends every three years, and don't jump at both ends every three years". Therefore, the lunar calendar stipulates that non-neutral months are leap months, and the following months are called leap months. If there is no gas in April 2020, it will be April after April.

This is a very interesting question and a good one.

Your question is actually two, solar terms and leap years.

Let's talk about the first one, "Who invented the twenty-four solar terms in the lunar calendar". Here, I want to point out your two mistakes: first, the lunar calendar is not correct. China's calendar is divided into solar calendar and lunar calendar, and it is a combination of yin and yang. The lunar calendar is not a standard reference. Generally speaking, the lunar calendar is the lunar calendar, which is the fifteenth day of the first month. It takes the moon as the background, reflecting rain or shine. The solar calendar is based on the sun, and the 24 solar terms are not lunar calendar but solar calendar.

Twenty-four solar terms are the twenty-four solar terms of the earth's revolution around the sun in a tropical year, which change all year round, spring, summer, autumn and winter. This is the solar calendar, not the lunar calendar. According to legend, it was discovered (not invented) by the Yellow Emperor, but actually earlier.

Yan nian or solar calendar. One tropical year is 365.25 days, four tropical years are one full day, Yan year is 366 days, and every four years.

Yan nian is not an invention, but a discovery, which was before the Yellow Emperor, at least 5,000 years ago.

The twenty-four solar terms of the China lunar calendar were definitely not invented by an ancient man. They have long observed the relationship between astronomical phenomena and the sun in farming season, and summed up the 24 solar terms.

In ancient times, people all over the world initially measured time according to the full moon and the full moon, 355 days a year, 12 months in * * *.

The ancient economy was mainly agriculture and animal husbandry, all of which depended on the weather for food. It is found that the growth of crops and grass has nothing to do with the movement of the moon, but is directly related to the movement of the sun. So the solar calendar was invented. The original calendar was abandoned and only used by sailors.

The ancients in China first used the lunar calendar to measure time, which China called the lunar calendar. It was also found that the lunar calendar did not conform to the agricultural season, and the solar calendar was invented, with 365 days a year. At that time, the Gregorian calendar did not use decimal notation, but used the 60-decimal notation, but the Gregorian calendar divided 365 days a year into 24 solar terms. Each solar term corresponds to the farming season and guides farming. So the 24 solar terms are solar calendars, not lunar calendars.

China is the most traditional, unlike the ancient Egyptians and Greeks who abolished the lunar calendar. Invented the solar calendar or reluctant to abandon the lunar calendar, come up with a compromise. Time is still calculated according to the lunar calendar. A certain day refers to the lunar calendar, and the 24 solar terms are opposite to the solar calendar. This kind of lunar calendar is called lunar calendar, but it is actually solar calendar.

There are 365 days in the solar calendar and 355 days in the lunar calendar, which is less than 10 days per year. The ancients were very wise and reluctant to use lunar and solar calendars. What shall we do? So I came up with three years and more than one month, which is the reason of leap year. Jumping on the moon has nothing to do with good or bad luck. Don't be fooled by Master X and fortune tellers.

The current lunar calendar is an improved version after the Republic of China, with the solar calendar as the main body and February as a year. But the timing method of the 24 solar terms and the lunar calendar is retained.

The lunar calendar is useless except for recording major festivals and can be completely abandoned.
