What is a leap month?

What is leap month and what is its function? In the Gregorian calendar (Gregorian calendar), 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. 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. In the Gregorian calendar (Gregorian calendar), 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. 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.

What is a leap month? What are the flat and leap months in the solar calendar? It refers to February 29, once every four years, and the average month refers to February 28.

What does the lunar leap month mean? This means that there are two identical months in that year. For example, a year is a leap April, that is, there are two April in a year. However, there are two months in April of the lunar calendar that do not affect the lunar calendar, and the months of the lunar calendar are still counted as usual. .

What do leap years and leap months mean? There are 365 days, 5 hours, 48 minutes and 46 seconds in a year. However, the number of days in a year must be an integer, so a year is 365 days, and the remaining 5 hours, 48 minutes and 46 seconds accumulate to one day in April, so one day is added every four years, which is called "leap year". A year without leap days is called "average year", with 365 days in average year and 366 days in leap year.

However, after four years of leap, it's only 23: 00, 15 minutes and 4 seconds. Today is more than 44 minutes and 56 seconds, which adds up to 100 years, which is 17: 58 minutes and 24 seconds, which is about three quarters of a day. Therefore, a leap is wasted every hundred years, and it will not be wasted until the 400th year. If it is a leap every four years and every 400 years, it will take more than 2: 53 minutes and 20 seconds, and it will take eight 400 years, that is, 3200 years, to make up for the difference the next day.

The lunar calendar is based on the new moon. The time of the first month of the lunar calendar is 29. 5366 days, so the lunar calendar is also 30 days for the big month and 29 days for the small month. The size of the lunar calendar is determined by calculation, and sometimes there may be two big months or two consecutive small months. Because the first month of the lunar calendar is slightly longer than 29 and a half days, there are about 53 big months and 47 small months in every 100 calendar month. The lunar calendar basically takes 12 months as a year. But the time of 12 moon is 354. 3667 days, which is about 1 1 day different from the tropic year of the solar calendar, so there will be 33 days more every three years, that is, one month more. In order to eliminate the extra days, one month will be added every three years, which is the leap month of the lunar calendar. A year with a leap month is called a leap year, so the leap year of the lunar calendar has 13 months, and which month to run depends on the solar terms.

Which month of the lunar leap depends on the 24 solar terms in a year. The twenty-four solar terms of the China lunar calendar are divided into twelve solar terms and twelve solar terms. The twelve solar terms are: beginning of spring, Jingzhe, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Hanlu, beginning of winter, Heavy Snow and Slight Cold; The twelve kinds of qi are: rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, great summer heat, summer heat, autumn equinox, first frost, light snow, winter solstice and severe cold. The twenty-four solar terms of the lunar calendar are postponed month by month. So in some lunar months, the gas drops at the end of the month, and it will be out of gas next month. This coincides with the year when we need leap month. Therefore, it is stipulated in the lunar calendar that only neutral months are considered leap months, and the following months are called moist months. For example, in 2006, July 30th of the lunar calendar will be the Mid-Autumn Festival, so there will be no Mid-August Mid-Autumn Festival, so July is a leap year.

What does leap month mean? 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 only called leap year and leap month, and the solar calendar is also called the year of the rooster.

In the Gregorian calendar (Gregorian calendar), 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.

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.

How to calculate leap month is a way to set leap in calendar. In Asia (especially in China), leap month refers to one month added every leap year in the lunar calendar (in order to coordinate the contradiction between the tropic year and the lunar year and prevent the lunar year from being out of touch with the tropic year and the four seasons, 1 leap and 19 leap are set every two to three years). Sometimes, a leap month also refers to a month that includes a leap day in a leap year (especially in February of a leap year in the Gregorian calendar). A leap month is an additional month in every leap year. In the lunar calendar, the length of the first lunar month (29.5306 days) is the average of one month, which is 65438+February in the whole year, which is about 10 and 2 1 hour different from the tropic year (365.2422 days), so it is leap in turn, one month in three years, two months in five years and seven months in nineteen years. A leap month is called "leap month" after a certain month. For example, the last leap month in 2009 was May (June 23rd, 2009-July 2nd, 20091), and the upcoming leap month of 20 12 was April (20 12). What we usually call "leap year" is actually a rough figure. Then there are 365 days in a year, which is O.2422 days different from the actual year, so four years later, it is nearly one day less than the actual year. In order to make up for this difference, the calendar stipulates that four years is a leap year, that is, a year divisible by four is a leap year, and additionally stipulates that every century year (a year with two zeros at the end) must be divisible by 400 to be a leap year. For example, 1996 is a leap year, and 2000 is also a leap year, but 1700 is not. The leap year in the solar calendar has 29 days in February, the leap day is February 29 and the leap year in the solar calendar has 366 days. That is to say, February of leap year in the solar calendar is not called leap February, and leap month is unique to the lunar calendar. Now let's talk about "leap month". Leap moon refers to a phenomenon in the lunar calendar. The lunar calendar arranges the big moon and the small moon, that is, the moon, according to the full and short moon. The length of a moon is 29.5306 days, which is the cycle of the moon's profit and loss. According to the lunar calendar, there are 30 days for the big moon and 29 days for the small moon, and a year is 12 months * * 354 days. Lunar month has no seasonal significance, so its length is 29.5306× 12=354.3672 days, which is less than 365.2422 days in the tropic year (that is, near 1 1 day) 10.88 days, and 0.9/kloc per month. The difference between solar calendar year and year is 1 1 day. Only after 17 will the date of the lunar calendar be reversed in the same season. For example, a year's New Year is spent in the snow, and a new year comes after 17. The use of such a calendar naturally cannot meet the needs of agricultural production, so the lunar calendar in China has been in parallel with the 24 solar terms since the Qin and Han Dynasties, and the 24 solar terms are used to guide agricultural production. Many people misunderstand the lunar calendar in China and often confuse it with the lunar calendar. There are three calendars in the world: one is the solar calendar, in which the time for the earth to go around the sun is one year, and the number of months and days in a year can be specified artificially; One is the lunar calendar, in which the time for the moon to circle the earth is one month, and only a few months in a year can be designated artificially; The third is the yin-yang calendar, that is, the average time for the moon to orbit the earth is January, but by setting leap months, the average number of days in a year is equal to the average time for the earth to orbit the sun, such as the lunar calendar and Tibetan calendar in China. Therefore, the lunar calendar in China is not a lunar calendar, but a combination of yin and yang. The lunar and solar elements in the lunar calendar have their own uses. The lunar calendar can indicate the moon's profit and loss, and can also predict the tides. The solar calendar is more useful. Twenty-four solar terms are a great invention in ancient China. It shows the position of the earth in orbit, reflects the annual apparent movement of the sun, and is most suitable for guiding agricultural activities. Therefore, the traditional lunar calendar in China is called the lunar calendar. Therefore, the lunar calendar is different from the lunar calendar, and it is not appropriate to call the lunar calendar the lunar calendar. The sun and the moon are calendars that people hang in the sky. Year after year, the earth revolves around the sun, and everything on the earth lives and multiplies in the cycle of the sun and the moon. 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 the contradiction. In order to overcome this shortcoming, we ... >>

China Lunar Leap Month: Which month is the leap month? Leap year, leap April, leap May and leap June are the most, leap September and leap October are the least, and leap November, leap December and leap January will not appear (here are a bunch of guys, this sentence is the key point)

What is a leap month? If we calculate every few years according to our existing 365 days in a year, there will actually be a few more days in a year, but these extra days are not average, so we have no choice but to add up the extra days in a year and make up a whole month at a certain time. This is a leap month.

The purpose of leap month is to avoid the strange phenomenon that the time is inconsistent with the calendar and the time sequence is disordered and reversed. On the basis of astronomical observation, our ancestors found out the method of "leap month", 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 at the same time ensuring that the first year of the lunar calendar is in late winter and early spring (all above refer to lunar season).

It's like the number in our division can't be divisible, but there is a remainder. A few more remainders can form an integer, just like a leap month. There is a leap month every four years.
