Why is there a leap month in the lunar calendar? The leap month in the lunar calendar 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 the lunar year, with a length of 29.5306× 12=354.3546 days, which is 10.88 days less than the regression, and about 1 1 a month less than 0.9 1 day.

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

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

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, and 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 the first month of the lunar calendar of 29.5306 days, 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 is a new moon, the arrangement of large and small months is not fixed, but needs to be determined through strict observation and calculation. Therefore, it is common to be big or small for two consecutive months in the lunar calendar, even with rare exceptions. For example, March and April are small in 1990, while four consecutive months are big in September,1October,1month and1February.

So how often do you add leap months? The best way is to find the least common multiple of the number of days in tropical years and the number of days in lunar months: 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 find m and n directly, but we can find 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 19 tropic year must be added with 7 leap months.

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).

After seven leap months were added to the tropical year 19, the contradiction was 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 seven leap months, that is, the "19-year seven leap method", which well coordinates the tropic year and the lunar year, so that the Lunar New Year's Day (Spring Festival) 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, and the moon in the lunar calendar has distinct moon phase characteristics, which maintains the best characteristics of both the Gregorian calendar and the lunar calendar.

At present, the method of setting leap is between two winter solstice days. 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 the first month without "neutral spirit" appears, this month is a leap month, and its name is to add the word "leap" in front of the previous month.

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

Question 6: Birthday is in March. How many years does it happen? Birthday is in March, how many years? 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 per 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 in the same month from February to 10, and the repeated months are leap months. For example, the leap month after April is called leap April.

.

Lunar leap year leap month calculation, 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, 200 1, 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 degree with the 24 solar terms of the lunar calendar;

The number of leap months in the lunar calendar is the same as that in normal months, both of which are 29 or 30 days.

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

The following is a comparison table between Gregorian calendar 1982 and lunar leap year since 2042.

Calculation method of leap year: Divide by 4 but not by 100 or divide by 400 is leap year. According to the above calculation method of leap year and the conditions of leap March; There is no thirteenth month in the lunar calendar. According to the calendar rules, leap months are repeated in the same month from February to 10, and the repeated months are leap months. For example, the leap month after March is called leap March. )
