Of all the ancient calendars in the world, how many years is this year.

Our motherland is always in the past. The lunar has always been counted, mainly because the gravitational pull of the moon has almost affected some of nature...

Western countries use the solar calendar. It is the earth on the ecliptic plane. Count for each lap. If you really count the records. Of course, you have to start with.

After having a word. It should have been more than 7,000 years now...

The lunar year is 12 or 13 months, the number of days in each month is 29 or 30 days according to the moon's orbit around the earth, 13 months in leap years, 353 or 354 days in a normal year and 384 or 385 days in leap years, with an average of about days (i.e., the time it takes for the earth to circle the sun) in a meso-year.

The lunar calendar basically has a cycle of 19 years, which corresponds to the same time in the Gregorian calendar. For example, May 27, 2001, May 27, 1982 and May 27, 1963 in the Gregorian calendar are all the fifth days of the fourth month of the leap month.

The month to which the leap month is added is inferred from the rules of the lunar calendar, and is mainly determined according to the correspondence with the 24 solar terms of the lunar calendar. Since the beginning of the winter solstice, every singular number is the solar term, and the even number of the reed is the middle air, such as the turn of a month only the solar term and no middle air, that is, the leap month of the previous month. The number of leap months in the lunar calendar is the same as the number of days in a normal month, which is 29 or 30 days.

The first year of the Chinese lunar calendar is generally 12 months, and the number of days in each month depends on the cycle of the moon around the earth, which is 29 or 30 days in Laochang. Among them, the month with the leap year is 13 months, with 384 or 385 days.

At the same time, in order to avoid the months of the solar calendar and the months of the lunar calendar getting bigger and bigger, leap months are used to make up for it. In 19 years, there are 7 leap month years. Generally, it is the beginning of spring before the Spring Festival of the lunar calendar, and there is no leap month in the second year. After the Spring Festival and the beginning of spring, there will be a leap month this year.

In general, the Chinese lunar calendar generally has 354 or 355 days in a year, and in years with leap years, it is 384 or 385 days.

a year in the Chinese lunar calendar;

In a normal year, it is about 350 days;

A leap year is about 380 days.

This is mainly because the lunar calendar itself is an artificially regulated calendar, and there is also the concept of leap months, so the time of the lunar calendar itself belongs to a big cycle, and at the same time it is not the same as each other.

Whenever we talk about calendars, we first distinguish between the solar and lunar calendars, which are what we often refer to as the lunar calendar. In ancient society, people at that time used the lunar calendar to calculate time, and we can also understand the calculation method of the lunar calendar as our traditional culture.

Many important festivals themselves will also be counted in the lunar calendar. <>

The lunar calendar and the solar calendar themselves have this certain difference.

Traditional Chinese calendar.

There is a calendar called the lunar calendar, which in China is called the lunar calendar. The lunar calendar is a new calendar created by our ancestors in order to meet the long-term and complex needs of human production, life and development. The solar calendar is a Western-style democratic calendar, which was developed by the ancient Greeks.

and other countries. The solar calendar is a new type of lunar calendar formed and developed by the Chinese according to the idea of yin and yang opposition, which is a leap month method formulated and implemented according to the law of the sun's operation. <>

The lunar calendar itself will have this certain difference in the length of the month and the length of the date.

You can try to understand it this way, because our farmers themselves belong to the artificial normative calendar, and the length of the months of each month is different. If we only have the lunar calendar in one year, the lunar calendar will basically not change much. But if we stretch the timeline to three or even 10 years, we will find that the time difference between the lunar calendars is very large, and even some months will reach a difference of about a month.

In this case, of course, there may be a direct confusion between the concepts of the lunar calendar and the solar calendar, and at the same time, the ability to misunderstand the solar calendar will also be misunderstood. <>

In addition, because the lunar calendar itself is a calendar calculated by the change in the height of the sun, there will be a certain difference in this calculation method, so this difference may also lead to a certain error in the distinction between the lunar calendar and the solar calendar, and the length of this error will produce a certain difference according to the specific situation of each year.

It is because the autobiographical speed of the earth around the sun is also different, resulting in the number of days in each year, but in order to take a whole number, the number of days in the lunar calendar is different.

We know that in fact, we are not in leap years, and the number of days in leap years and ordinary years is not the same, and the speed of the earth's rotation also varies, so a year is not exactly 365 days. As a result, the number of days in the lunar calendar is different each year.

The main reason why the number of lunar days is different every year may be that there is a great difference with the date changes and calculation methods of each year, so this situation will occur, but it can also be seen that the rigor of China's lunar calendar.

There are 365 days, and the 365 days of a year will not change according to the solar calendar, but will only be fast and slow.

The oldest calendar in China was introduced during the Yuan DynastyTiming calendar, used for a total of 364 years, this calendar was analyzed according to data after a long period of observation by ancient astronomers.

It was calculated nearly 300 years earlier than the Western calendar that was also accurate in terms of accuracy. Let's take a look at the ancient calendar.

The time calendar was officially implemented in 1281, and the Jin State was used at the beginning of the Yuan Dynasty.

This calendar lacks scientific basis, the observational data are not accurate, and with the accumulation of time, the recorded time error is getting larger and larger, therefore, Kublai Khan.

He ordered the revision of the new calendar, he convened a large number of ancient astronomers to carry out a comprehensive restoration and rectification of the existing astronomical observation instruments in the country, and then spent many years to collect astronomical data from all over the country, and finally revised the chronological calendar under the precise calculation of many astronomers.

The chronological calendar appeared more than 300 years earlier than the Western calendar with the same accuracy, which means that China's astronomy was in a leading position in the world at that time. This large-scale calculation activity preserved a lot of astronomical data for the Yuan Dynasty, which was also of great help to the study of other knowledge. With the Ming Dynasty, Zheng He went to the West.

The development of activities and the introduction of the calendar to other countries have also played a certain positive role in promoting the development of the modern calendar.

The main compilers of the calendar were Xu Heng and Guo Shoujing.

Wang Xun. They are not only outstanding astronomers and mathematicians in ancient China, but also representatives of Chinese literati. They studied and researched for decades, and in addition to the time-honored calendar, Xu Heng also formulated the official system of the Yuan Dynasty, and Guo Shoujing was also responsible for the construction of the Grand Canal.

Wang Sui created the calendar rate calculation method, and they all made great contributions to the development of ancient countries in China.

The oldest calendar used in China is the chronological calendar. At the beginning of the Ming Dynasty, the time grant lasted for 364 years, so Chang Ranzi said that the "Time Granting Calendar" was the longest calendar in the history of our country. In addition to the advent of the calendar to guide agricultural production, it was also used by the ancients to keep time.

The oldest calendar used in ancient China was the Shixian calendar, which was enacted at the end of the Ming Dynasty, so the period is still relatively old.

The chronological calendar, which took a total of 364 years, is a long time to use.

A total of 354 or 355 days in 12 months of the year.

The lunisolar calendar is the lunar calendar of our country, which promotes the length of the solar calendar to avoid the shortness of the lunar calendar, determines the "month" according to the waxing and waning cycle of the moon, and takes the time when the earth revolves around the sun, that is, a return year, as the average length of the year. The lunar calendar stipulates that the big month is 30 days, the small month is 29 days, and the 12 months of the year are 354 or 355 days, which is about 11 days less than the return year, and it is less than 1 month in 3 years.

Over time, there will be a phenomenon of timing and time disorders. For example, the Spring Festival in 2002 falls on February 12 of the solar calendar, which is the cold winter season; In 2003, the Spring Festival was held on February 1 of the solar calendar, 11 days earlier than the previous year, in order to solve this problem, the lunar calendar adopted the "19 years and 7 leaps" method, that is, 12 ordinary years in the 19 lunar years, 12 months per year; For the other seven years, one month is added each year to 13 months, and this additional month is called a "leap month."

The use of "19 years and 7 leaps" in the lunar calendar is not to avoid the confusion of the time sequence caused by the lunar calendar and the Gregorian calendar. It is the adjustment of the lunar calendar (lunisolar calendar) itself to its solar part and lunar part out of sync, and after adding 7 leap months in the 19th year of the lunar calendar, it roughly ensures that the average length of a year in the 19th year of the lunar calendar is about 365 and 1 4 days.

Therefore, if there is no leap month in the lunar calendar of the previous year, then the Spring Festival of the next year will be about 11 days earlier than the previous year; If there was a leap month in the lunar calendar of the previous year, the Spring Festival of the next year will be about 19 days later than the previous year. Therefore, the solar calendar date of the Spring Festival is not fixed.

The lunar year is 354 days, which is calculated according to the month when the moon orbits the earth. The lunar year is sometimes 12 months and sometimes 13 months. The year with a leap month is 13 months.

The solar calendar (365 days a year) has more than 11 days per year than the lunar calendar (354 days a year), and in order to avoid the months of the solar calendar and the lunar calendar getting bigger and bigger, leap months are used to make up for it.

There are 7 leap months in 19 years. Generally, it is the beginning of spring before the Spring Festival of the lunar calendar, and there is no leap month in the second year. After the Spring Festival and the beginning of spring, there will be a leap month this year.

The months of the year in the solar calendar are 31 days and 30 days. February is generally 28 days. February 4 has a 29-day day.

The number of days in a lunar year is not fixed, there are only about 354-355 days in the twelve lunar months of a year, and the length of the calendar month of the lunar calendar is based on the synodic month, with 30 days for the big month and 29 days for the small month, and the big month and the small month make up for each other, making the average length of the calendar month close to the synodic month.

The lunar calendar does not consider the movement of the earth around the sun, so that the change of the four seasons has no fixed time on the lunar calendar, and the solar year is fixed at 365 days or 366 days, the lunar year is sometimes different from the solar year in the number of days by one month, in order to coordinate the number of days between the lunar year and the solar year, so that the total number of lunar moon phase days corresponds to the total number of days in the solar return year.

The lunar calendar is one of the traditional Chinese calendars, and many traditional festivals in China are set by the lunar calendar, such as the Spring Festival, Lantern Festival, Mid-Autumn Festival, Double Ninth Festival, etc.

There are 365 days in a common year, 366 days in a leap year, and the year in a leap year can be divisible by 4, such as 2004, 2008, etc., and everything else that is not divisible by 4 is a common year. The difference is that there are 28 days in February in a normal year and 29 days in February in a leap year.

It is usually said that there are 365 days in a normal year and 366 days in a leap year.

According to the ancient Chinese calendar, a year starts from the beginning of spring, according to 24 festivals, 10 belong to 2 sections, 12 qi. The beginning of spring is the beginning of the Yin month, the sting is the beginning of the Mao month, and the Qingming is the beginning of the Chen month......The twelve feasts are the beginning of the twelve months. The local time of each year is determined by the summer day, and the year is divided into twelve parts, (divided into twelve parts).

The time of a year is 365 days, 6 hours, 9 minutes, and seconds, about a day. The time of each month is one-twelfth. According to the monthly calendar, the moon orbits the earth for one month, and the moon orbits the earth for 27 days, 7 hours, 43 minutes and seconds.

Gregorian calendar 365 days in a common year and 366 days in a leap year.

In the lunar calendar, a year is generally 12 months, the number of days in a month is 29 or 30 days according to the moon's orbit cycle around the earth, 13 months in leap years, 353 or 354 days in a normal year in the Chinese lunar calendar, 384 or 385 days in a leap year, and an average of about one day per year (that is, the time it takes for the sun to orbit the earth).

Oh, that's really good.

Come laugh on the lunar calendar.

There are three days in a normal year from 12 months:

Five big months and seven small months are 353 days (e.g., 1965), six big months and six small months are 354 days (e.g., 2005), seven big months and five small months are 3 days (e.g., 2003), and there are three days in the thirteen months of a leap year, (there are leap months, i.e., one more month) six big months and seven small months are 383 days (e.g., 1993), and seven big months and six small months are 384 days (e.g., 2004 Jiashen year), Eight big months, five small months, 385 days (e.g. 2006).

A common year is 10 to 13 days less than a Gregorian year, and a leap year is 17 to 20 days longer than a Gregorian year.

The Gregorian calendar has a leap year, and the lunar calendar has a leap month Leap year is a phenomenon in the solar calendar, fixed in February, one day more than the usual year, 29 days; Leap months are in the lunar calendar.

A phenomenon, leap month, that year has 13 months in the lunar calendar, that year is called a leap month year. The leap year is 384 days. Unlike the Gregorian calendar, the leap month of the lunar calendar is always set in February; There are also solar terms, which are not generally fixed like the Gregorian calendar, and its calculation is more complicated, and the number of days in a common year and a leap year differs by many days, so the use of the Gregorian calendar is more common and convenient than the lunar calendar.

If you look up the book "Perpetual Calendar", you can clearly know which year of the lunar calendar is a leap year and which month is a leap year.
