Are the lunar calendar and the lunar calendar the same thing? Are the lunar calendar and the lunar calendar the same date?

Introduction: It is often said that the lunar calendar is the lunar calendar, but some people say it is different. So who is right? Are the lunar calendar and the lunar calendar the same thing? Are the lunar calendar and the lunar calendar the same date? Lunar calendar and lunar calendar are two concepts, which can be said to have certain differences, but they are not exactly the same. The following is my introduction to the lunar calendar and the lunar calendar. Interested friends have a look.

Are the lunar calendar and the lunar calendar the same thing?

The lunar calendar is not a lunar calendar. It is also called lunar calendar, lunar calendar, ancient calendar, Han calendar, yellow calendar, summer calendar and old calendar. There are still differences in the calculation methods between the lunar calendar and the lunar calendar.

Although the lunar calendar is called "lunar calendar" in rural areas, it is not a pure lunar calendar. It is a mixed calendar of "lunar calendar" and "dry calendar" (24 solar terms), which is what we call "yin and yang combined calendar" The lunar calendar takes into account the relationship between the sun, the moon and the earth! Therefore, the lunar calendar is not a "pure lunar calendar", the 24 solar terms are dry calendars, the solar calendar is a combination of yin and yang, the Gregorian calendar is a Gregorian calendar, and the AD is a calendar starting with the birth of Jesus.

The lunar calendar is mainly based on the calendar in which the earth revolves around the earth for one month, that is to say, according to the plastic moon. The lunar calendar is also called "Li Yin"! With the continuous development of the calendar, it was not until the appearance of the twenty-four solar terms that the lunar calendar was formed, that is, the "Han calendar"! But China is currently using the "Yin and Yang Calendar".

In China, the lunar calendar was basically used in ancient times, because it is easier to observe the plastic moon corresponding to the "tropic year"! As we all know, according to the solar calendar, the earth's orbit around the sun is 365 days, while according to the plastic moon, it is roughly 354 days a year. So there is a leap month.

The lunar calendar determines the moon according to the law of its movement: the orbit of the moon is called the white road, and both the white road and the ecliptic are two great circles on the celestial body, which intersect at five degrees and nine minutes. The moon goes around the earth and appears on the ecliptic twice, which lasts for 7 hours and 43 minutes 1 1.5 seconds on the 27th, and is called "Stellar Moon". Only when the moon revolves around the earth, the position of the earth also changes. The forward count is more than 27 degrees, and the moon runs 13 degrees 15 minutes every day, so it takes 12: 44: 2.8 to return to the moon on the 29th, which is called "the first moon", and it is called the moon according to customs, which means the first moon.

Strictly speaking, the traditional calendar in our country should not be called lunar calendar, it is a lunar calendar. Now it is called "Lunar Calendar", which is the result of the so-called "four old" during the Cultural Revolution. In fact, this name is also very inappropriate. Its seasonal date can wander for as long as a month, which is not very suitable for agricultural production. To be exact, it should be called "Han Li". This title is based on the rules of the Han Calendar proposed by Emperor Wu of the Han Dynasty and the title of this calendar in the Imperial System of Emperor Kangxi of the Qing Dynasty. This calendar has been called "Han Calendar" since ancient times.

Are the lunar calendar and the lunar calendar the same date?

Generally speaking, it's the same. "For example, today is the third day of the lunar calendar, is it also the third day of the lunar calendar?" Correct.

Deep discussion: the lunar calendar is based on the cycle of the moon (that is, the moon). Because the ancients called the moon the lunar calendar, it is also called the lunar calendar, which is a pure lunar calendar. In China, the term "lunar calendar" is used, and most people call it "lunar calendar", which is wrong. The lunar calendar is not a pure lunar calendar, but a "yin and yang calendar". The lunar calendar takes the full and short periods of the moon as one month, and 12 months as one year. However, the moon has a full moon, which is 29 days, 12: 44: 3, which is more than 29 days and less than 30 days. For convenience, the lunar calendar divides months into two types: big month and small month. 30 days in a single month, 29 days in a double month, a total of 354 days in a year.

In fact, the new moon is not exactly equal to the average of the big moon and the small moon-29 days and a half, but 44 minutes and 2.8 seconds more than 29 days and a half. So 12 moon is actually 8 hours, 48 minutes and 34 seconds longer than 354 days, and it will be 1 1 day in 30 years. Therefore, a leap year 1 1 will be inserted in the 30 years of the lunar calendar, and an extra day will be added in the 12 months of each leap year. The leap year in the lunar calendar is 355 days. So every 30 years, the lunar calendar has 19 354 days and 1 1 355 days, and the average length of a year is 354 days, 8 hours and 48 minutes. Its year is almost shorter than the tropical year 1 1 day. In three years, we lost more than a month, and 17 lost more than half a year. So with this length of time, the New Year doesn't have to be spent in winter, but it can be spent in spring, summer and autumn. Its only advantage is that the shape of the moon can be known on every date of the lunar calendar. As a calendar, the lunar calendar is not in harmony with agricultural production and people's daily life, so in today's world, except for a few Islamic countries that are still in use for religious reasons, other countries have generally abandoned it.

The lunar calendar takes the time of the first month of the lunar calendar as the average time of the calendar month. This is the same as the pure lunar calendar, but the lunar calendar adopts the method of setting leap months and 24 solar terms, so that the average length of the calendar year is equal to the tropic year, which has the elements of the solar calendar, so it is better than the pure lunar calendar. It is said that our ancestors used this calendar in all lunar calendars as early as the Xia Dynasty (before17th century BC). So people also call it the summer calendar. After liberation, it was still called the summer calendar. After 1970, it was renamed as the "Lunar Calendar" in China. As for the origin of the name "lunar calendar", it is probably because the country has been founded on agriculture since ancient times, so the calendar must serve agriculture. The lunar calendar is based on the new moon. The time of the first lunar month is 29th 12 hours, 44 minutes and 3 seconds (that is, 29.5366 days), so the lunar calendar is also 30 days for the big month and 29 days for the small month, but it is not exactly the same as the pure lunar calendar, because the pure lunar calendar is arranged alternately with big and small months, and the size and month of the lunar calendar are determined by calculation. The first day of each month in the lunar calendar happens to be a "new moon" (that is, the moon is in the middle of the sun and the earth faces the earth with half of the darkness). Sometimes there may be two big months or two small months in a row. Because the first month of the lunar calendar is slightly longer than 29 and a half days, there are about 53 big months and 47 small months in every 100 calendar month of the lunar calendar.

The lunar calendar basically takes1February as a year, but the time of 12 lunar month is 354.3667 days, which is about 1 1 day different from the tropical year. In this way, there will be 33 extra days every three years, that is, one more month. In order to eliminate the extra days, one month is added every three years, which is the leap month of the lunar calendar. A year with a leap month is also called a leap year. Therefore, the lunar leap year has 13 months. As for the leap month, it is determined by the solar terms. China calendar has a long history. "History? Yao Dian has "What is the fate, Qin Ruohao's sky, calendar like the sun, the moon and the stars, respecting the people", "The stars and birds are in the sun, Yin Zhongchun; The sun is always shining for midsummer; In the night, the stars are empty and cloudy; It is recorded that the short star in the middle of winter has six days in 360 years, and the leap month will set the age at four o'clock. Although Shangshu was entrusted by later generations, it was not enough to prove that the length of each tropical year was 366 days at that time, but for agricultural activities, "year" was the most important cycle. This is what people in primitive society got from production practice. The calendar of our country adopts the method of counting branches. Before the Eastern Han Dynasty, only days were recorded, and years were recorded after the thirty years of Jianwu (54).
