How often does the lunar calendar produce leap months? Is there a pattern to which leap month?

The leap month of the lunar calendar is once in 3 years, twice in 5 years, and seven times in 19 years!

What month is the leap month in the lunar calendar? It is decided on the 24 solar terms of the year.

The Chinese lunar calendar divides the 24 solar terms into 12 solar terms and 12 middle terms.

The lunar calendar is based on the moon (lunar calendar), and the 12-month calendar has a total of about 354 days; Combined with the almanac (Gregorian calendar), the almanac is based on the cycle of the four seasons formed by the rotation of the earth. The monthly calendar is shorter than the annual calendar, with a difference of 11 days, so it is necessary to add 7 more leap months every 19 years to fill in the error. The decision to make a leap month in that month depends on the twenty-four solar terms, and the lunar month usually contains a solar term and a mid-term, such as the autumn equinox, etc., if a lunar month only has solar terms and no mid-terms, the calendar will add one more month to the month as a leap month.

Taking 2006 as an example, the seventh month of the lunar calendar happened to be a month with solar terms and no neutral terms, so the leap month was used to adjust the error.

The dates of the 24 solar terms in the lunar calendar are postponed month by month, so in some lunar months, the mid-air falls at the end of the month, and there is no mid-air in the next month.

Generally, every two years or so, there is a month without a mid-term month, which coincides with the year when a leap month is needed. Therefore, the lunar calendar stipulates that the month without Zhongqi is regarded as a leap month.

For example, the 29th day of the fourth lunar month in 2001 is the middle air small full, and the first day of the new year next month is the next summer solstice.

In other words, which month does not have a mid-air leap month, so there is no fixed rule for which month to leap. If you want to know which monthly run is the most popular, you have to count it yourself! But I can tell you which month has the least number of leaps:

That is the wax month, and there has not been a leap month in this month. However, it is estimated that the year 3358 will be the first time in history that there will be an unprecedented leap month! In other words, there will be two years that year!

But it's none of our business. Hehe.

The leap month of the lunar year is every two or three years, or more precisely, there are seven leap months in every 19 years on average.

The time is uncertain, sometimes once every two years, sometimes once every 3-4 years, irregular.

The lunar calendar is a lunisolar calendar: its years are divided into ordinary years and leap years. Twelve months in a normal year; Leap years are thirteen months. The months are divided into big months and small months.

There are thirty days in the big month and twenty-nine days in the small month.

Its average calendar month is equal to one synodic month. Which month of the year is older and which is smaller is determined by calculation.

Advantages of the lunar calendar:

1.The lunar calendar is a lunisolar calendar, which takes into account the relationship between the sun, the moon and the earth. The lunar calendar is a fixed calendar, which has the characteristics of an astronomical calendar, and can correspond well to various celestial phenomena, such as its solar terms strictly correspond to the height of the sun.

The calendar day corresponds more strictly to the phases of the moon.

The frequency of non-occurrence and occurrence of leap months correspond to the perihelion and aphelion of the Earth.

Other celestial phenomena such as sunrise and sunset, morning and dusk shadows, five-star orientation, solar and lunar eclipses, tides, etc., and even the calendar months roughly correspond to the height of the sun.

2.There are only 29 days and 30 days in the lunar calendar month, and they are stipulated by the fixed date, and the human factor is small, and it is not easy to change at will.

3.The beginning of the year has strong astronomical significance, and has the astronomical significance of the lunar month and the yang year.

There are seven leap months every 19 years in the lunar calendar. It depends on which year there is a leap month or which leap month it is.

Lunar leap months are generally held once every three years.

I can understand the leap month of the lunar calendar, the leap of the lunar calendar in the lunar calendar, there is a pattern. The lunar calendar used in China is not just a calendar, but a lunisolar calendar. The solar calendar is reflected in the 24 solar terms, and the lunar calendar is the lunar calendar, which reflects the changes in the phases of the moon.

The lunar calendar has no impact on agricultural production, and the solar term calendar is formulated according to the characteristics of the sun's operation law, the operation of the sun and the four seasons, there are different cold and summer, cold and hot differences, so the solar term calendar can guide agricultural production, and the lunar calendar should be used with the solar term calendar.

Chinese people have long observed the movement of the sun and the moon, and created the solar calendar and the lunar calendar, and they are also used together。Now it is accurately known that a solar return year is 365 days, 5 hours, 48 minutes and 46 seconds, the calendar, the day is the base unit, and the calendar day must be rounded, so the solar calendar year takes 365 days in the ordinary year, and the rest is not counted, and then the leap back one day after four years, there are leap days, into 366 days, and the year with leap days is called leap years. The solar calendar is a leap year, according to the solar calendar, leap years are also regular, basically every four years, can be divided by 4 as a leap year.

The year 2020 is divisible by 4, so it is a leap year, according to this law, 2024, 2028, etc., basically all years divisible by 4 are leap years.

The moon is full and missing cycle time is 29 days 12 hours 44 minutes 3 seconds, the calendar day is rounded, take the month 30 days, the month is 29 days, a year of December, that is, 354 or 355 days, the number of days and the solar calendar year difference of 11 days, and the lunisolar calendar to use, in order not to lose the season too far, to make up for the difference between the year and the day, so to short the long, the lunar calendar set leap month to accommodate。It has been calculated that after setting 7 leap months in 19 years, the maximum approximate overlap between the number of days in the lunar year and the number of days in the solar year can be equal, and the difference is only one day. So the 19-year 7-leap method was adopted.

The law of leap months in the lunar calendar is 7 leaps in 19 years. As for the leap month, it depends on the solar terms. The law is that there is no mid-air in leap months.

The month of no leap, one festival and one air in January, is the month of leap, only the festival has no air. In the leap April of this year, I only see the mango seed festival, but I don't see the summer solstice, and the summer solstice is on the first day of the fifth month.

The 24 solar terms are formulated according to the characteristics of the sun's operation, and the characteristics of its festival month are that the winter festival month is relatively short, less than 30 days, and the summer festival month is relatively long, more than 30 days。It is noon before March, and there are the most leap months, especially in May, which occurs once in ten years on average, which is the law of leap months in the lunar calendar.

The leap month of the lunar calendar is calculated according to the law of movement of the earth, and a leap month will be set every three years, and an average of 19 years needs to use the month period four, so as to ensure that yin and yang match each other, I don't understand the leap month of the lunar calendar, I think he is more complicated.

I think the leap month is a phenomenon in the lunar calendar, a leap month, then the lunar calendar of the year will have 13 months, this year is called a leap year, if it is a leap month, then there will be 384 days in a year; I can understand the leap month of the lunar calendar.

The law of leap months in the lunar calendar is that there must be a leap month in four years, a leap month in two years, and a second leap month in nineteen years. I can understand the leap month of the lunar calendar.

Once every 4 years, the understandable lunar calendar, in life there will be once every few years, which is very normal, there is a month in the leap month year will appear twice.

Many people will wonder why there is a leap month in the lunar calendar, so the author will talk about the reason why there is a leap month in the lunar calendar; From ancient times to the present, according to the ancestral tradition, the year is divided into 12 months, and the lunar year is composed of 12 synodic months, so in the lunar calendar, the length of a synodic month is a day, to ensure that the first day of the month is the first day of the new year must be a new day, so there is a big month and a small month, the big month is 31 days, and the small month is 29, in addition, we are talking about 365 days a year, and the accurate number in essence should be a year, so that the actual number of days after 4 years is nearly one day less than the actual year, Then, in order to make up for this gap, the legislation provided for a four-year leap period.

Leap month is also a special phenomenon in the lunar calendar, in the lunar calendar the big month is 30 days, the small month is 29 days, so that a year is a total of 12 months, a total of 354 days, in order to meet the 24 solar terms, and began to recalculate, the lunar calendar is less than the solar calendar 11 days a year, at the beginning of the ancestors every three years plus a month called the leap month, but found that this is not accurate enough. It was changed to add two leap months every 5 years, so that it was found that there were three or four more days than the actual one, and finally, after repeated observation of the celestial phenomena and the actual results, the calculation determined the 19-year 7-leap method, that is, 7 leap months between 19 years, this algorithm is more accurate. Among them, the Chinese scientist Zu Chongzhi creatively also proposed 144 leap months in 391 years, which is more accurate, but it is difficult to calculate.

It can be seen that the lunar calendar is sometimes 12 months, sometimes 13 months, which has strict scientific laws, which deal with the solar terms, so for example, the month containing rain is January, and you also have the month of the spring equinox as February, and so on.

To sum up, a leap month is a phenomenon in the lunar calendar, a leap month is a month, the lunar calendar has 13 months in that year, and if it is a leap year, it is a phenomenon in the solar calendar, fixed in February with one more day than the usual year.

It is understood that the reason for the leap month in the lunar calendar is a phenomenon in the lunar calendar, and the so-called leap month is based on the 24 solar terms.

China is an ancient cultural country with a history of 5,000 years, in our country there are a lot of excellent traditional culture is worth inheriting, you can also see that the ancients in our country are very wise, many times their ideas are very advanced to the present, they have also brought us a lot of excellent historical achievements, so that we modern people can sit back and enjoy it. China has its own way of calculating the days is our lunar calendar, which is different from the Gregorian calendar.

We know that in a certain year of the lunar calendar, there may be a leap month, and the moon means that there is one more month, in the calculation of the lunar calendar, there are 13 months in this year, that is, in ancient China, the way to calculate the days, that is, the way of yin and yang, yin represents the moon, yang represents the sun, they are there a certain difference, if you want to make the lunar calendar days and the solar calendar days perfectly opposite, you must produce a leap month, so when you reach the return year, there will be a leap month. According to our ordinary understanding, in fact, the occurrence of leap months is actually to reconcile the gap between the lunar and solar calendars, so that their contradictions begin to disappear.

We must know that the moon is actually a phenomenon in the way the lunar calendar calculates the days, and the lunar calendar mainly calculates the days by observing the changes of the moon, so we can see that the moon is cloudy and sunny, which means that we also have certain twists and turns in the time of the year. There are 24 solar terms in a year, and if you want to be completely opposite to the days of the lunar calendar and the days of the solar calendar in this year, it is actually very impossible, but if you want to achieve a unity and reduce this contradiction, then you must run the moon.

The lunar calendar, which is widely circulated in China, is mainly based on the amount of time the moon orbits the earth. And take into account the relationship between the earth and the sun. The lunar months are calculated by the time it takes for the Moon to make one revolution around the Earth.

The moon orbits the earth for a little more than 29 days, so the lunar months are 30 days for the big month and 29 days for the minor month. In this way, the lunar year is only 354 or 355 days. The Gregorian calendar, on the other hand, is calculated based on the time it takes for the Earth to revolve around the Sun, and it takes a little more than 365 days for the Earth to revolve around the Sun.

In this way, the lunar calendar lasts more than 11 days less than the solar calendar.

Leap years are created to compensate for the difference between the number of days of the year and the actual orbital cycle of the earth caused by the man-made calendar.

A leap month is a way of placing an intercalary in the calendar. In Asia (especially in China), a leap month refers to a month that increases every leap year in the lunar calendar (in order to reconcile the contradiction between the return year and the lunar year, and to prevent the lunar year from being out of touch with the return year and the four seasons, 1 leap is placed every 2 to 3 years, and 7 leap years are placed in 19 years).

The time is uncertain, sometimes once every two years, sometimes once every 3-4 years, irregular.

The lunar calendar is a lunisolar calendar: its years are divided into ordinary years and leap years. Twelve months in a normal year; Leap years are thirteen months.

Months are divided into major months and minor months, with the major month having 30 days and the minor month having 29 days, and its average calendar month is equal to one synodic month. Which month of the year is older and which is smaller is determined by calculation.

1. Leap month: 1 leap month every 2 to 3 years.

The so-called leap month is an extra month in the year, which is to coordinate the contradiction between the return year and the Han calendar year, and to prevent the Han calendar year from being out of touch with the return year and the four seasons, and to place a leap month every 2 to 3 years. In other words, the new calendar will have 13 months in the year, and the calendar that has been modified to favor agricultural activities is the lunar calendar. Leap months were created to reconcile the contradictions between the lunar and solar calendars.

The lunar calendar has an average of only about 354 days in a year, which is 11 days less than the Earth's orbital cycle. This is reflected in the situation in ancient times, the most direct is that the year is over, and the four seasons are not yet finished. Ancient China was an agrarian society, and subsequent changes directly guided agricultural affairs.

In order to align the calendar with the cycle of the four seasons, the ancients decided to artificially increase the length of the year, so they set leap months on the basis of the lunar calendar.

2. In the lunar calendar, the leap month appears after which month is called the leap month, for example, the leap month in 2017 appeared after the sixth month of the lunar calendar, so it is called leap June.
