What March has a leap year! ? Determination of leap month in lunar calendar

Each month contains two solar terms. The working people in ancient times called the first solar term (beginning of spring, Jing Zhe, Qingming, Long Summer, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Cold Dew, beginning of winter, Heavy Snow and Slight Cold) "solar term". The last solar terms (rain, vernal equinox, Grain Rain, Xiaoman, Summer Solstice, Great Summer, Early Summer, Autumn Equinox, Early Frost, Light Snow, Winter Solstice and Great Cold) are called "Zhongqi". How to arrange the lunar leap month? In the history of our country, there have been different ways to deal with it. The leap month was placed at the end of the year in the Western Han Dynasty, and it was called "the last September" in the early Han Dynasty. After the Han Dynasty, the month without neutrality was designated as the leap month of the first lunar month, and this rule of placing leap has continued to this day.

Why is a lunar month not neutral? The results show that the average interval between two neutral gases is 365.2422÷ 12=30.4368 days, then 30 or 3 1 day. The earth's orbit around the sun is elliptical and moves slowly at the perihelion (vernal equinox and autumnal equinox), and the interval between the two solar terms can reach 3 1.45 days. On the other hand, the average lunar new moon is only 29.5306 days, including 29 days in the first lunar month and 30 days in the second lunar month. In this way, there will be such a situation: in some months (usually abortion), the last breath has passed at the beginning, and the next breath has not come at the end. For example, 200 1 (New Year's Eve) is May 21(April 29), and the first day of the next lunar month is May 23. However, this lunar month ends on June 20, and the summer solstice is June 2 1, so this lunar month is not "neutral", it falls in the fourth month of the lunar calendar. This year's vernal equinox is on March 20th (February 30th), the first day of the next lunar month is on March 2nd1,and ends on April18th, and the third day is in Grain Rain on April 20th. In this way, the month after February of this year's lunar calendar without "neutral gas" is designated as leap February. According to this leap law, it will leap in July 2006, May 2009, April 20 12, September 20 14, June 20 17 and April 2020.

As for the lunar month, this involves the solar terms. There are 24 solar terms in a year, which is just a traditional saying. In detail, it should be said that there are twelve solar terms and twelve neutral terms in a year. Which of the twelve qi belongs to which month is regular: rain is the qi of the first month; The vernal equinox is in mid-February; Grain Rain is the spirit of March; Xiaoman is the spirit of April; The solstice in summer is mid-air in May; The summer heat is in mid-June; Summer heat is the qi of July; The autumnal equinox is in mid-August; The first frost is the breath of September; Light snow is the neutral atmosphere in October; The winter solstice is 1 1 mid-month; It's freezing in mid-air in December.

As for which month the twelve solar terms are in, it is not necessarily so. A month in the lunar calendar averages a little more than 29 and a half days, but the average interval from one breath to the next is less than 30 and a half days. In this way, the monthly air in the lunar month will be delayed by 1 day. At a certain time, qi is not in the middle of the month but moved to the end of the month. If next month is a miscarriage, there will probably be no gas in this month, because the gas will be moved to the beginning of the third month. The middle month is not neutral, even if last month was a leap month. Take 1998 as an example: June 2 1 day in the solar calendar is May 27th of the lunar calendar, which is the summer solstice (mid-May); But July 23rd in the solar calendar is the first day of June in the lunar calendar, and this day is the summer heat (the qi of June). From June 24th to July 22nd of the Gregorian calendar (one month after the end of May of the lunar calendar), there is only one solar term, and this month is leap May. Therefore, leap month is determined by people according to certain laws, which is not mysterious.

In the China lunar calendar, a year with a leap month is called a leap year. The general year is 12 months, 354 or 355 days, and the leap year is 13 months, 383 or 384 days. As a kind of lunar calendar, the number of days in each month depends on the monthly loss, and the time of one year is based on 12 months. In order to close the earth's cycle around the sun, that is, the tropic year, one month is added every two to four years, and the added month is a leap month, so the leap year of the lunar calendar is 13 months.

There is no thirteenth month in the lunar calendar. According to the calendar rules, leap months are repeated from February to the same month after 10, and the repeated months are leap months. For example, the leap month after April is called leap April.

Calculation of leap month in lunar leap year, three-year leap, five-year leap, 19 leap; The lunar calendar basically takes 19 as a cycle, corresponding to the same time in the Gregorian calendar. For example, on May 27th of Gregorian calendar 200 1 year, ... >>

The year of leap March in the lunar calendar is between 1949 and 2050, and the years of leap March are: 1955, 1966, 1993, 203 1 and 2050.

Calculation of leap month in lunar leap year, three-year leap, five-year leap, 19 leap; The lunar calendar basically takes 19 as a cycle, corresponding to the same time in the Gregorian calendar. For example, in the Gregorian calendar, May 27th, 2006, 5438+0, May 27th 1982 and May 27th 1963 are the fifth day of leap April.

The month of the leap month is inferred according to the laws of the lunar calendar, mainly according to the coincidence with the 24 solar terms of the lunar calendar;

The number of leap months in the lunar calendar is 29 or 30 days, just like normal months.

The so-called "leap" in the lunar calendar is just called leap year and leap month, and there are also leap years in the solar calendar.

Why is there a leap month in the lunar calendar? The lunar leap month is to coordinate the contradiction between the tropic year and the lunar year.

What is the contradiction between the tropic year and the lunar year? Remember first: the total length of the tropic year is 365.2422 days, and the length of the first lunar month is 29.5306 days.

12 lunar months constitute lunar years, with a length of 29.5306× 12=354.3546 days, which is 10.88 days less than the regression and about 1/kloc-0 less than the monthly 0.9 1 day.

Accordingly, if the Spring Festival in one year of the lunar calendar is a snowy winter, the Spring Festival in the next year will be 1 1 day earlier than the season, and 16 Lunar New Year will appear in the hot summer.

If the lunar year consists of thirteen lunar months, the length is 29.5306× 13=383.8978 days, which is more than the tropic year 18 days.

If the calendar is made according to the above regulations, there will be a strange phenomenon that the weather is inconsistent with the calendar and the time order is disordered and reversed-this is contradiction.

In order to overcome this shortcoming, our ancestors found the method of "leap month" on the basis of astronomical observation, ensuring that the first month to March is spring, April to June is summer, July to September is autumn, and October to December is winter, while ensuring that the first year of the lunar calendar is in late winter and early spring.

The mid-year month of the lunar calendar is based on the length of 29.5306 days in the first lunar month, so the big month is 30 days and the small month is 29 days. In order to ensure that the first day of each month (the first day) must be a new moon, the arrangement of large and small months is not fixed and needs to be determined through strict observation and calculation. Therefore, it is very common to be big or small for two consecutive months in the lunar calendar, and even there are rare exceptions, such as 1990 in which March and April are small, and 9, 10,1,1February are big for four consecutive months.

So how often do you add leap months? The best way is to find the least common multiple of the number of days in the tropical year and the number of days in the lunar month: we hope that the number of days in m tropical years is equal to the number of days in n lunar months, that is, there should be an equation:

m×365.2422=n×29.5306

In this equation, we can't directly find out m and n, but we can find out their proportions:

The approximate value of this ratio is:

In these fractions, the numerator represents the number of tropical years and the denominator represents the number of moons. For example, the sixth score means that seven leap months must be added to 19 tropical year.

Comparison of the results of adding 7 leap months in 19 tropical year;

19 tropical year =19× 365.2422 = 6939.438+018 (days)

A lunar month has 29.5306 days, and 235 lunar months = 235× 29.5306 = 6939+38 days.

19 tropic year plus 7 leap months, the contradiction is eliminated: 6939.438+00-6939.18 = 0.0892 (days)-that is, more than 2 hours and 9 minutes, which is accurate enough.

Therefore, the lunar calendar adopts the method of 19 plus 7 leap months, that is, the "19 7 leap month method", which well coordinates the return year and the lunar year, so that the New Year's Day (Spring Festival) of the lunar calendar is always kept in the late winter and early spring. The ancients called 235 new moons "leap weeks".

The method of placing leap in the lunar calendar can make the average length of the lunar year close to the tropic year. The moon in the lunar calendar has distinct moon phase characteristics, which keeps the best characteristics of both the solar calendar and the lunar calendar.

At present, the method of setting leap is between two winter solstice. If it is only 12 months, it is not a leap; if it is 13 months, it is a leap. The leap month begins on the "winter solstice". When there is no "neutral spirit" in the first month, this month is a leap month, and its name is to add the word "leap" before the previous month.

What month is the lunar leap month? It depends on the 24 solar terms in a year.
