How to calculate the lunar year

How to calculate the date of the lunar calendar is a set of methods for calculating the date based on the operation of the ancient sun.

Generally, there will be a leap year every four years, that is, one more day every four years.

Knowledge about the lunar calendar

Lunar calendar (summer calendar, lunar calendar, ancient calendar, yellow calendar, old calendar)

The lunar calendar takes the time of the first month of the lunar calendar as the average time of the calendar month. This is the same as the pure lunar calendar, but the lunar calendar adopts the method of setting leap months and 24 solar terms, so that the average length of the calendar year is equal to the tropic year, which has the elements of the solar calendar, so it is better than the pure lunar calendar.

It is said that our ancestors used this calendar in all lunar calendars as early as the Xia Dynasty (before17th century BC). So people also call it the summer calendar. After liberation, it was still called the summer calendar. After 1970, it was renamed the China Lunar Calendar. As for the origin of the first place in the lunar calendar, it is probably because the country has been founded on agriculture since ancient times, so the calendar must serve agriculture.

The lunar calendar is based on the new moon. The time of the first lunar month is 29th 12 hours, 44 minutes and 3 seconds (that is, 29.5366 days), so the lunar calendar is also 30 days for the big month and 29 days for the small month, but it is not exactly the same as the pure lunar calendar, because the pure lunar calendar is arranged alternately with big and small months, and the size and month of the lunar calendar are determined by calculation.

The first day of each month in the lunar calendar happens to be a new moon (that is, when the moon is in the middle of the sun and the earth faces the earth with a dark half). Sometimes there may be two big months or two small months in a row. 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 of the lunar calendar.

The lunar calendar basically takes1February as a year, but the time of 12 lunar month is 354.3667 days, which is about 1 1 day different from the tropical year. This will add 33 days every three years, that is, an extra month.

In order to eliminate the extra days, one month is added every three years, which is the leap month of the lunar calendar. A year with a leap month is also called a leap year. Therefore, the lunar leap year has 13 months. As for the leap month, it is determined by the solar terms.

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 three 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.

Another name for lunar month

January: the first month, the second month, the month of Meng, the end of the month, beginning of spring and beginning of spring;

February: such as the moon, apricot moon, mid-spring and early spring;

March: Sick Month, Peach Month, Ji Chun, Bingyue, Sanchun, Yangchun and Late Spring;

April: Yuyue, Qinghe, Taoyue and Xia Meng;

May: Job Liu Yue, midsummer;

June: and month, lotus month, Xia Yue, late summer month;

July: Meet, Qiao Yue, Shuangyue, Qiu Meng and the same month;

August: Zhuangyue, Gui Yue, Mid-Autumn Festival, Mid-Autumn Festival;

September: autumn, auspicious sea and moon, gathering the moon;

October: Yangyue, Xiaoyangchun and Germination;

November: Gu Yue, Jiayue and Midwinter;

December: Tuyue, Twelfth Moon, Jiapingyue and Jidong.

The first ten days of a lunar month are customarily called the first day. For example, the second day of the first month of the lunar calendar is called the second day of the first month. Of course, it is also correct to say 65438+10.2.

The first month of the lunar calendar (the first month of the year) begins after 65438+1October 20th and before the end of February. For example, the first day of the first lunar month may be 65438+10.21,or it may be February 20; Conversely, the last day of the Lunar New Year is 65438+1from October 20th to the end of February.

How to calculate the day and month of the lunar calendar with heavenly stems? Chronology of ancient China. That is, Party A, Party B, Party C, Party D, Party E, Party B, Party G, Party A, Party B and Party B are ten, while Party A, Party B, Party C, Party B, Party C, Party D, Party B, Party B and Party B are twelve, and the branches are coordinated in sequence. Such as Jia Zi and Yi Chou, will return to Jia Zi after 60 years. It goes on and on. In China, the lunar calendar still uses the calendar year of cadres and branches.

The chronology of the dry branch sprouted in the Western Han Dynasty, began with Wang Mang, and prevailed in the late Eastern Han Dynasty. In the second year of Emperor Yuanhe of the Han and Yuan Dynasties (AD 85), the court ordered the nationwide implementation of the chronicle of cadres. Some people think that China used dry branches to record the years before Emperor Wu of the Han Dynasty. However, this is the Gregorian calendar year of the Prince, which is based on the Gregorian calendar year of the Prince, and the branch represents twelve days (the ecliptic is divided into twelve equal parts). Jupiter 1 1.862 revolves around the sky once a week, so it takes about 86 years for Tai Sui to pass through an old age, which is the so-called "Chen Chao". In the Calendar of Zhuan Xu, the first year of Tai Chu (BC 104) of Emperor Wu of the Western Han Dynasty was the prince of Bingzi, and taichu calendar changed it to Ding Chou by surpassing Chen. At the end of the Han Dynasty, Liu Xin changed the first year of Taishu to Bingzi, and the second year of Taishi (the first 95 years) from Yiyou to Bingxu. Scholars who returned to the eastern Han dynasty did not use the super-Chen method. So from the second year, the chronology of the prince and the chronology of the main branch are the same. However, according to legend, the chronology expressed by heavenly stems and earthly branches began in the period of the Yellow Emperor, and 60 pieces of Jiazi table were found in Shang Dynasty archaeology in Yin Ruins.

1. The meaning of trunk and branch: trunk and branch are the general names of heavenly stems and earthly branches.

Dry refers to heaven, * * * with 10 symbol:

1 2 3 4 5 6 7 8 9 10

Methyl ethyl propyl butyl hexyl heptyl octyl non decyl

Refers to the earth, * * * with 12 symbol:

1 2 3 4 5 6 7 8 9 10 1 1 12

The child is ugly, and the mother hasn't applied this afternoon.

2. The combination of stem and branch is used for dating. That is to say, the ten-day stem and the twelve-day branch are combined to form the stem and branch for dating. According to this arrangement method, 60 branches can be formed after six rounds of arrangement 10 symbols and five rounds of arrangement 12 symbols for ground branches on the same day. If it continues to be discharged, it will return to its original state again and again, which is what the folks call "sixty years of turning to Jiazi".

[Edit this paragraph] Understand the "Twelve Branches" in combination with the actual situation

1. Match twelve animals with twelve earthly branches to form the Year of the Zodiac. (See the picture below) If the year of the main branch contains the word "zi", it is the year of the rat, and all the people born in this year are "rats"; The Year of the Ox is a year of ugliness, and all the people born in this year belong to the ox. And so on. (as shown in the following table)

How to calculate the month of the lunar year? The lunar calendar is based on the laws of the moon's movement: the moon's orbit is called the white road, and both the white road and the ecliptic are two great circles on the celestial body, which intersect at five degrees and nine minutes. The moon goes around the earth once, and it appears on the ecliptic twice, with a calendar of 7 hours and 43 minutes 1 1.5 seconds on the 27th, which is the time required for the moon to go around once, and is called "sidereal moon". Only when the moon revolves around the earth, the position of the earth also changes. The forward count is more than 27 degrees, and the moon runs 13 degrees 15 minutes every day, so it takes 12: 44: 2.8 to return to the moon on the 29th, which is called "the first moon", and it is called the moon according to customs, which means the first moon.

The lunar calendar is based on the changes of the moon's profit and loss. The period of a lunar month is twenty-nine or thirty days, and the length of a year is only an integer multiple of the month, which has nothing to do with the tropic year. The moon in the lunar calendar refers to the period of about 29.5 solar days required for the moon to make a circle around the earth. Associated with the appearance of the moon, it can show the changes of the moon round after round. The month has nothing to do with the four seasons. Greek calendar and hijri calendar belong to this kind of calendar. It is impossible to have a "double spring" or a "blind year" in a year.

The lunar calendar is based on the law of the earth's movement: the earth revolves around the sun once, that is, the moon revolves around the earth for twelve weeks and one-third of a week, and the number of months in a year can't be odd zero, so there are only 354 days in twelve months of a year, which is about 1 1 day compared with the real year, totaling three years and 33 days. So there must be a leap month every three years and stay for three days. Leap month is a month without festivals, leap year is a leap year, and leap year has thirteen months. A month is a leap month, and the name of the month depends on the name of the previous month. For example, the previous month is August and the leap month is leap August. The average year is twelve months. There are 12 months in the lunar calendar, 354 or 355 days in the whole year, 13 months in leap years and 383 or 384 days in leap years.

Because the number of days in a month cannot be odd zero, a month in the lunar calendar is the 29th or 30th. Every month is headed by the day of the first day, that is, the first day. Every year, the new moon near beginning of spring is the beginning of the year.

How to calculate the lunar leap year? A leap year in the lunar calendar is a year that includes leap months.

As we know, the total length of a tropical year is 365.2422 days, while the length of a lunar month is 29.5306 days, and the length of twelve lunar months is 29.5306× 12=354.3546 days, which is about ten days. If we don't make up for it, the Spring Festival may arrive in summer in a few years.

In order to coordinate the contradiction between the tropic year and the lunar year, our ancestors found out the method of adding seven leap months in 19, that is, "seven leap months in nineteen years", which coordinated the tropic year and the lunar year well, and kept the New Year's Day (Spring Festival) of the lunar calendar at the end of winter and the beginning of spring. 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.

The twenty-four solar terms of the China lunar calendar are divided into twelve solar terms and twelve neutral terms, among which odd-numbered solar terms (such as beginning of spring) are called solar terms and even-numbered solar terms (such as rain) are called neutral terms.

The lunar calendar takes the moon as the cycle (lunar calendar), and the December calendar is about 354 days. Combined with the almanac (solar calendar), the almanac is compiled according to the four-season cycle formed by the revolution of the earth. The monthly calendar is shorter than the annual calendar by 1 1 day. Therefore, it is necessary to add 7 leap months every 19 years to make up for the error. Deciding which month is a leap month depends on 24 solar terms. Lunar months usually include a solar term and a neutral atmosphere, such as the autumnal equinox. If a lunar month has only solar terms and no neutral atmosphere, one more month will be added to the calendar as a leap month. Taking 2006 as an example, July of the lunar calendar happened to be a month with solar terms but no neutral atmosphere, so there was an adjustment error in July.

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. Naturally, that month was a leap year. ...

How to calculate the annual Chinese New Year? The lunar calendar in our country is the lunar calendar. Is to consider the movement of the sun and the moon at the same time. Among them, 24 solar terms return completely according to the sun. Therefore, the solar calendar date of each solar term is basically certain, while the lunar calendar date is far apart. But the lunar calendar is based on the monthly moon profit and loss. As we all know, the first day is always a new moon, looking forward to the fifteenth.

In the Chinese lunar calendar, the beginning of a year is actually a household registration. When we say "Xu Bing Year" and "Jiazi Year", we should start from beginning of spring. This is the calculation of "time horoscope". Many people in China don't know this. But beginning of spring has nothing to do with the moon phase. The lunar month must start from the first day, that is, from the new moon. Therefore, the new moon closest to beginning of spring is considered as the first day of the first month, that is, the Spring Festival. But this day is sometimes before beginning of spring and sometimes after beginning of spring. This is why there are often leap months in the lunar calendar.

How to calculate the date of the lunar calendar according to the date of the solar calendar: As mentioned earlier, the date of the lunar calendar is based on the full moon, with each new moon as the first day, the full moon is 15 (the 16th month) and the dark month is 29 (the 30th month). However, at present, the date of the solar calendar is usually used to express the time. If you want to convert the date of the solar calendar into the date of the lunar calendar, you can use the following two methods: one is to search the newly edited perpetual calendar, for example, what is the date of the lunar calendar on June 8, 1984? Open the perpetual calendar, 10 June is the eleventh lunar month, so it is inferred that June 8 is the ninth day of the ninth lunar month. Secondly, we can use the formula to calculate the lunar calendar date:

Suppose: the number of AD years-1977 (or1901) = 4q+r.

Then: Lunar date =14q+10.6 (r+1)+date ordinal of the year-29.5n.

(Note: Q, R and N in the formula are all natural numbers. R how to calculate the lunar calendar? How many days are there in a year? Because the new moon is easier to observe than the tropic of cancer, almost all ancient calendars are lunar calendars. Because the earth's orbit around the sun is 365 days, and the lunar December is only about 354 days, the ancients solved this problem by adding leap months. The calendar of our country has been a kind of yin-yang calendar since ancient times. Because the first day of each month is a new moon and the fifteenth day is a full moon, it is easy to identify and use, so it is usually called the lunar calendar. Leaping month is a way of calendar leap. In Asia (especially in China), the lunar leap month refers to the month added in each leap year of 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 set 7 leap 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). Lunar leap month is a month that increases 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 is May (June 23rd, 2009-July 2nd, 20091), and the upcoming leap month of 20 12 is April (20 12).
