How to calculate the lunar calendar?

How to calculate the lunar calendar in China? rule

In the lunar calendar, a year is generally 12 months, and the number of days in a month depends on the orbit of the moon around the earth, which is 29 or 30 days; The leap year is 13 months; In China, the average year is 353 or 354 days; The leap year is 384 or 385 days, with an average of about 365.2422 days per year (that is, the earth goes around the sun once).

The lunar calendar can be inferred as follows: the day when the moon moves to the earth and the sun in a straight line is the beginning of each month, which is called the first day. The longest day in a year between China and Japan is the summer solstice, and the shortest is the winter solstice. According to these two points, the year is divided into 24 equal parts, and 24 solar terms are obtained. Usually, the month of the latest lunar new year (Spring Festival) is the first month. The Spring Festival is in Gregorian calendar 65438+1from October 20th to February 20th.

As a kind of lunar calendar, the number of days per month depends on the monthly profit and loss, and the time of one year is based on 12 months; In order to close the cycle of the earth around the sun, that is, the tropic year, one month is added at regular intervals, 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, a leap month repeats the same month after any month, and the repeated month is a leap month. For example, the leap month after April is called leap April.

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, which is mainly determined according to the coincidence with the 24 solar terms of the lunar calendar. Since the winter solstice, odd numbers are solar terms and even numbers are neutral. If it is the turn of the month, only the solar terms are not neutral, that is the leap month last month.

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

How is the lunar calendar calculated? The length of the lunar calendar is based on the first lunar month, with 30 days in the first lunar month and 29 days in the second lunar month, which complement each other and make the average length of calendar months close to the first lunar month. Lunar New Moon is the first day of the month-the first day of the month. Astronomically speaking, the so-called "new moon" has a definite moment, that is, the ecliptic of the moon is the same as that of the sun. The calculation of the ecliptic is very complicated, so I won't introduce it here. As for the basis for determining the name of the month in the lunar calendar, it is determined by "Zhongqi". That is, the month containing "rain" is January; February is a month with "vernal equinox"; March is the month of Grain Rain; April is a month with "small fullness"; May is the month of "summer solstice"; June is the month of "great summer heat"; July is the month of "summer heat"; August is the month of autumnal equinox; September is the month of "first frost"; 10 is the month of "light snow"; 1 1 month is the month of "winter solstice"; 1February is the month of heavy snow. (The month without neutral gas is regarded as the leap month of last month) The length of the calendar year of the lunar calendar is based on the tropic year, but the days in a tropic year are more than 12 moons and shorter than 13 moons. When ancient astronomers compiled the lunar calendar, in order to make any day in a month contain the meaning of the moon phase, that is, the first day is moonless night and the fifteenth day is full moon. There are seven leap years and each leap year has thirteen months. Why adopt the method of "seven leaps in nineteen years"? The average lunar month is 29.5306 days, and there are 12.368 lunar months in a tropical year. The progressive scores of the fractional part of 0.368 are 1/2, 1/3, 3/8, 4/1,7/68. Because 19 tropical years = 6939. 18 days, and 19 lunar years (plus 7 leap months) have 235 lunar months, which is equal to 6939.88+00 days, the two are almost the same. Seven leap months are inserted for nineteen years, and the insertion method is exquisite. The position of the lunar leap month is completely artificial from ancient times to the present, and the position of the leap month has been different in all previous dynasties. Before the Qin Dynasty, the leap month was placed at the end of a year and was called "March". The leap month in the early Han dynasty was placed after September, which was called "post-September". In the first year of Emperor Wu of the Han Dynasty, leap months were inserted in every month of the year. Later, it was stipulated that "the month without neutral gas was the leap month of the previous month", which is still in use today. Why are there no gas in some months? The average interval between solar terms and solar terms, or neutral gas and neutral gas is 30.4368 days (that is, 65.2422 days in a tropical year is divided into 12 days), while the average interval in a lunar month is 29.5306 days, so the date of solar terms or neutral gas in the lunar month is postponed month by month. At a certain time, the neutral gas is not in the middle of the month, but moves to the end of the month, and the next neutral gas moves to the beginning of the next month. As mentioned above, when the ancients compiled the lunar calendar, they took twelve China Qi as the symbol of twelve months, that is, the rain was the symbol of the first month, the vernal equinox was the symbol of February, and Grain Rain was the symbol of March ... The month without China Qi was regarded as a leap month, which made the calendar name correspond to China Qi one by one, thus maintaining the original symbol of China Qi. From the seventh leap of 19, the tropic year of 19 has 228 solar terms and 228 neutral qi, while the lunar calendar 19 has 235 new months. Obviously, there are seven months without solar terms and seven months without neutral atmosphere, so it is logical to designate the months without neutral atmosphere as leap months. The size of the lunar month is very irregular, sometimes two, three, four big months or two three small months are connected together, and the length of the calendar year varies greatly. The distribution dates of solar terms and gas in the lunar calendar are very unstable and vary greatly. In this way, the lunar calendar seems very complicated. In fact, the lunar calendar still has a certain cyclical law: because the number of days in the 19 tropic year is almost equal to that in the 19 lunar year, every 19 lunar year is almost the same. Every nineteen years, the Gregorian calendar day on the first day of each month in the same month of the lunar calendar is generally the same or different by one. & gt

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 is the lunar calendar calculated?

The length of the calendar month in the lunar calendar is based on the first month of the lunar calendar, with 30 days in the first month and 29 days in the second month. The first lunar month and the second lunar month complement each other, making the average length of calendar months close to the first lunar month.

Lunar New Moon is the first day of the month-the first day of the month. Astronomically speaking, the so-called "new moon" has a definite moment, that is, the ecliptic of the moon is the same as that of the sun. (The calculation of the ecliptic of the Sun and Moon is very complicated, so I won't introduce it here. )

As for the basis for determining the name of the lunar month, it is determined by "Zhongqi". That is, the month containing "rain" is January; February is a month with "vernal equinox"; March is the month of Grain Rain; April is a month with "small fullness"; May is the month of "summer solstice"; June is the month of "great summer heat"; July is the month of "summer heat"; August is the month of autumnal equinox; September is the month of "first frost"; 10 is the month of "light snow"; 1 1 month is the month of "winter solstice"; 1February is the month of heavy snow. There is no month with neutral gas like last month's leap month.

The calendar year of the lunar calendar is based on the tropic year, but a tropic year is more than 12 months and less than 13 months. When ancient astronomers compiled the lunar calendar, in order to make any day in a month contain the meaning of the moon phase, that is, the first day is moonless night and the fifteenth day is full moon, with the moon as the main factor, taking into account the seasons. There are seven leap years and each leap year has thirteen months.

Why adopt the method of "seven leaps in nineteen years"? The average lunar month is 29.5306 days, and there are 12.368 lunar months in a tropical year. The progressive scores of the fractional part of 0.368 are 1/2, 1/3, 3/8, 4/1,7/68. Because 19 tropical years = 6939. 18 days, and 19 lunar years (plus 7 leap months) have 235 lunar months, which is equal to 6939.88+00 days, the two are almost the same.

Seven leap months are inserted for nineteen years, and the insertion method is exquisite. The position of the lunar leap month is completely artificial from ancient times to the present, and the position of the leap month has been different in all previous dynasties. Before the Qin Dynasty, the leap month was placed at the end of a year and was called "March". The leap month in the early Han dynasty was placed after September, which was called "post-September". In the first year of Emperor Wu of the Han Dynasty, leap months were inserted in every month of the year. Later, it was stipulated that "the month without neutral gas was the leap month of the previous month", which is still in use today.

Why are there no gas in some months? The average interval between solar terms and solar terms, or neutral gas and neutral gas is 30.4368 days (that is, 65.2422 days in a tropical year is divided into 12 days), while the average interval in a lunar month is 29.5306 days, so the date of solar terms or neutral gas in the lunar month is postponed month by month. At a certain time, the neutral gas is not in the middle of the month, but moves to the end of the month, and the next neutral gas moves to the beginning of the next month.

As mentioned above, when the ancients compiled the lunar calendar, they took twelve China Qi as the symbol of twelve months, that is, the rain was the symbol of the first month, the vernal equinox was the symbol of February, and Grain Rain was the symbol of March ... The month without China Qi was regarded as a leap month, which made the calendar name correspond to China Qi one by one, thus maintaining the original symbol of China Qi.

From the seventh leap of 19, the tropic year of 19 has 228 solar terms and 228 neutral qi, while the lunar calendar 19 has 235 new months. Obviously, there are seven months without solar terms and seven months without neutral atmosphere, so it is logical to designate the months without neutral atmosphere as leap months.

The size of the lunar month is very irregular, sometimes two, three, four big months or two three small months are connected together, and the length of the calendar year varies greatly. The distribution dates of solar terms and gas in the lunar calendar are very unstable and vary greatly. In this way, the lunar calendar seems very complicated. In fact, the lunar calendar still has a certain cyclical law: because the number of days in the 19 tropic year is almost equal to that in the 19 lunar year, every 19 lunar year is almost the same. Every nineteen years, the Gregorian calendar day on the first day of each month in the same month of the lunar calendar is generally the same or one day apart ... >>

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).

How to calculate the algorithm of lunar calendar? 5 points 1. Calculation of lunar rules;

The calculation of solar terms and the time of the first lunar month shall be based on East longitude 120 degrees and China Standard Time.

(Lunar calendar is based on Purple Mountain Observatory, Chinese Academy of Sciences)

Second, first of all, you need to know the following common terms:

Zodiac: it is the coordinate value used to determine the position of celestial bodies on the celestial sphere in the ecliptic coordinate system, which is divided into 360 degrees. In this system, the celestial sphere is divided into two hemispheres by the ecliptic plane. When the sun runs at 0 degrees of the ecliptic, it is the vernal equinox, when it runs at 90 degrees of the ecliptic, it is the summer equinox to the sun, when it runs at 180 degrees, it is the autumn equinox, and when it runs at 270 degrees, it is the winter equinox to the sun.

Shuori: The day when the moon moves between the earth and the sun is called Shuori.

Pingshuo: calculated by the average length of the moon, regardless of the inequality between the sun and the moon; Disadvantages: "The day containing the real" new moon "may sometimes appear on the last day of the previous month ("dark day ",29th or 30th), and sometimes on the second day of junior high school".

Deciding the new moon: the inequality between the sun and the moon is taken into account in the calculation, and the day of the real "new moon" is taken as the beginning of each month.

Homogeneous level: the uneven motion of the sun on the ecliptic is not considered in the calculation, and the first anniversary (tropic year) is divided into 24 solar terms, and the average number of days between the two solar terms is 15.22 days.

Fixed Qi: Considering the uneven movement of the sun on the ecliptic, the days between the two solar terms of fixed Qi are different, the short one is only 14 days, and the long one is 16 days.

Winter solstice: the day when the winter solstice is handed over is called winter solstice. The winter solstice must be in the second month: set the day of the winter solstice or the day before the winter solstice as the "starting point" of the first day of the second month (note: the starting point is different from fortune telling).

Jian Zheng: In the first month of the year, the establishment of the lunar calendar is "Xia Zheng": the first month of establishing the summer calendar [the second month is 1 1 month];

Andrew: The first month of the lunar calendar is ugly [February and December], and the Lu calendar is the same as the lunar calendar;

Zhou Zheng: The Zhou calendar (Zhou Dynasty calendar) was built in the first month [February is the first month];

Qin Zheng: The Zhuan Xu calendar in Qin Dynasty was established in the first month, and October in Shanghai is the first month of the year.

Solar terms: A year is divided into twelve solar terms and twelve atmospheric festivals, with a total of twenty-four solar terms. Before Li Shixian in the Qing Dynasty (A.D. 1645), Li Shixian in the Qing Dynasty (A.D. 1645) marked a fixed atmosphere.

Third, the calendar:

Pay attention to the difference between annotation and calculation. The algorithm of determining the moon's sky was produced in Sui and Tang Dynasties, but it was blocked by conservative forces at that time and did not complete the transformation from flat sky annotation to fixed sky annotation. For example, when the monk and his party revised the Dayan calendar, they advocated the annotation of the gas, but the court did not adopt his theory. Finally, the fixed space algorithm is only used to calculate the solar eclipse, five-star arrangement and solar eclipse forecast before the end of Ming Dynasty. At the end of the Ming Dynasty, the calendar of Chongzhen was finally established after fierce debate.

Calendar: it can be divided into solar calendar, lunar calendar and yin-yang calendar;

Gregorian calendar: A year is divided into 12 months, which has nothing to do with the movement of the moon. According to the date of the solar calendar, we can know that the four seasons change from cold to summer, and guide agriculture reasonably. Gregorian calendar (scientific name Gregory calendar) is a kind of solar calendar.

Lunar calendar (lunar calendar): one month is the full and short term of the moon (that is, the new moon equals 29.50588 days), and the product of 12 months is one year. The annual apparent motion law of the sun is completely ignored, so the date of the lunar calendar can't show the warmth and coldness of the four seasons. This calendar is of little practical value, except for * * *, which has been abandoned.

Lunar calendar: China lunar calendar belongs to this category. It takes the moon phase, that is, the change cycle of the moon, as the month length and the return year of the sun as the age. By setting leap months, the average calendar year adapts to the tropic year. According to the date of the lunar calendar, we can not only know the ebb and flow of tides, but also grasp the changes of seasons.

Almanac: A publication that records calendars and other related information, such as yellow calendars and perpetual calendars. Electronic almanac is the product of scientific and technological development and a new carrier.

Fourth, the lunar rules.

The ancient definition of Japan is that the earth rotates once a day. When the sun is farthest from the horizon, it is equivalent to 23:00~ 1:00 Beijing time. But in the lunar calendar, a day begins at Zizheng (0:00) instead of Zizhu (23:00).

Monthly policy and final rule: the new moon is the starting point of each month (the first day); From the first day of the first month to the second day of the first month, there are as many days as there are in this month. The big moon has 30 days and the small moon has 29 days; Pingshuo was used before the second year of Wude in Tang Dynasty (AD 6 19), and Dingshuo was used after the second year of Wude (AD 6 19).

Year strategy and leap rule: the winter solstice must be in the next month (1 1 month), if there are1month from the previous winter to the sun and moon (1month) to the next winter to the sun and moon ... >>

Want to know how to calculate the lunar calendar 1 solar calendar? There is no calculation method, so it can only be arranged day by day. Because the lunar calendar is not as fixed as the solar calendar, the solar calendar is 1, 3, 5, 7, 8, 10, 12 and so on. It often has a wet month, and this wet month is not fixed, so there is no calculation method

2. The moon in the Yellow Emperor's Canon is the three seas of the lunar calendar.

3. The current solar calendar is the Gregorian calendar, which is also translated into the national calendar, the frontal calendar, the solar calendar and the Gregorian calendar, and is called the AD. Julian calendar was reformed by Italian doctor and philosopher aloysius Lilius and promulgated by Pope Gregory XIII in 1582.

How to calculate the lunar calendar and solar calendar? 10 method for calculating the Gregorian calendar date: 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 fifteen (the big moon is sixteen) and the dark moon is twenty-nine (the big moon is thirty). 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: In the formula, q, r and n are all natural numbers. How can the Gregorian calendar year of R be regarded as the Gregorian calendar year of heavenly stems and earthly branches? Each earthly branch corresponds to 24 solar terms from a certain solar term (non-neutral) to the next solar term, and the starting period is determined by the node time, not from the first day to the end of a certain lunar month. Many almanac shows that a lunar month corresponds to a branch, which is only approximate but not complete. In case of a or one's own year, the first month is roughly C Yin; B or Geng Year, the first month is roughly Wuyin; The first month of year C or Xin is roughly Geng Yin, the first month of Ding Nian or Ren Year is roughly Ren Yin, and the first month of year E or decyl is roughly Jia Yin. The first month is calculated according to the main branch, and other months are calculated according to the main branch. A cycle of 60 months and 5 years; Reuse after a cycle, cycle after cycle, cycle. In the 29th year of Jianwu (A.D. 53), the month from winter to the sun and the moon (the month from heavy snow to slight cold, similar to November of the lunar calendar) is the "Jiaziyue". There is a song to prove it: the first year of A is C, and the first year of B is E; Bing Xin must find Geng, and Ding is downstream; What's more, there is no way to find it, and it is not bad to pursue good news. The following table lists the corresponding solar terms, neutral atmosphere, approximate lunar month, approximate solar month, and monthly trunk branches composed of annual trunk and monthly trunk: the solar terms of monthly trunk are similar to those of lunar month A or B or C or D or E or E in beginning of spring-the first day of February, March, March, April, fifth month, fourth month, fourth month and fourth month. The fourth month, Grain Rain, Changxia, March, April, Chen Wuyue, Chen Geng Month, Renchenyue, Chen Jiayue, Chen Bingyue, Mitsuki, Changxia-Mangzhong Xiaoman April, May, Keith Month, New April, Gui April, Ye Si Month, April May Day, May Day, No Month, Slight Summer. —— Bailuyuan was appointed as Shen Yue in July and August, Shen Jiayue in Shen Bingyue in Wu Shenyue in Geng Shenyue in You Yue Bailu —— Cold Dew in Autumn Equinox in August and September, Gui You in Yi You Yue Ding You Yue Ji You Yue Xin has moonlight and cold dew —— beginning of winter first frost in September 65438+ October Xu Jiayue in Bing Wu Xue Yue Geng Xu Yue Ren Luo Ding Hai in Ji Hai in Xinhai, Yue Gui Hai in the month of heavy snow in November —— slight cold winter to November 65438.
