Which years have leap months, and which months? There is a leap month in May this year, and there should be a leap month every three years.

Please accept it, thank you!

There is a leap month every year. What months are it usually? There is not a leap month every year, but only once every three years.

Is 20 16 a leap month or a lunar calendar? Leap in August? 1998? Leap in May? 200 1? Leap in April? 2004? February leap

2006? Leap in July? 2009? Leap in May? 20 12? Leap in April? 20 14? Leap in September? 20 17? Leap in June? 2020? Leap in April? 2023? February leap

2025? Leap in June? 2028? Leap in May? 203 1? Leap in March? 2033? Leap in winter? 2036? Leap in June? 2039? Leap in May? 2042? February leap

So 20 16 is not a leap month, and 20 17 is a leap month.

Does the lunar calendar have a leap month every year? In the Gregorian calendar year, a year with leap days is called leap year, which is generally 365 days and 366 days. Because the earth's cycle around the sun is 365 days, 5 hours, 48 minutes and 46 seconds (365,438+09 days), which is the tropic year, the Gregorian calendar sets a year as 365 days. The remaining time is about one day in four years, plus February, so the normal year is 365 days, February is 28 days, leap year is 366 days, and February is 29 days. So every 400 years, there are 97 leap years, with one day added at the end of February and 366 days in leap years. Calculation method of leap year: the number of years in the calendar year can be divisible by four, which is a leap year; Divided by 100 but not divided by 400 is an average year; Leap years can be divisible by 100 or 400. For example, 2000 is a leap year, and 1900 is not.

The following is an example of calculating leap years in Gregorian calendar:

S = InputBox (please enter year:)

N = value

If n Mod 400 = 0 or (n Mod 4 = 0 and n Mod 100 0), then

MsgBox s+ is a leap year!

If ... it will be over.

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, 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.

How to calculate and know which year there is a leap month and which month is a leap year in the western calendar

A year with leap days in the solar calendar is called a leap year, and vice versa, it is 365 days in a normal year and 366 days in a leap year. In the Gregorian calendar year, February in a normal year is 28 days, and February in a leap year is 29 days. February 29th of a flat month in a leap year is a leap day.

Reasons for increasing leap days

At present, the Gregorian calendar takes the tropical year as the benchmark, and a tropical year is about 365.4220 days. Because the average calendar year is only 365 days, it will accumulate 0.24220*4=0.9688 days after four years, which is about equal to one day, so a leap day is added every four years to offset this 0.9688 days.

& gt03

Calculation method of leap year:

In the Gregorian calendar, most years divisible by 4 are leap years; A year divisible by 100 but not by 400 is not a leap year; Not a leap year divisible by 3200; For example, 1900 is a normal year, 2000 is a leap year and 3200 is not a leap year.

Leap year in China lunar calendar

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.

& gt05

The law that leap years follow: leap every four years, not leap in a hundred years, and leap again in four hundred years.

Leap year is a year with leap day in Gregorian calendar or summer calendar, and also a year with leap month in China lunar calendar.

There can't be two leap months in the lunar calendar year. According to the laws of the solar calendar and the lunar calendar, it is impossible to have two leap months in a lunar year unless the calendar you see is wrong.

Reason: It is impossible to have 14 new moons between two winter solstice days.

When will there be a leap month Calculation method of leap month

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 make up the lunar year, with a length of 29.5306× 12=354.3672 days, which is 10.88 days less than the regression, and about1/kloc-0 per month less than 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+38+08 (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.

In the China lunar calendar, 24 solar terms are divided into 12 solar terms and 12 neutral terms.

The date of the twenty-four solar terms of the lunar calendar is postponed month by month, so in some lunar months, the gas falls at the end of the month, and it will be out of gas next month.

Generally, there will be a month without gas every two years, which coincides with the year when leap months are needed. Therefore, the lunar calendar stipulates that non-neutral months are leap months.

For example, April 29th of the 200 1 lunar calendar is full of breath, and the first day of every other month is the next summer solstice. If there is no gas this month, it will be a leap month, after April, so it is called leap April. ...& gt& gt
