The origin of leap August
1995 belongs to the second year of the lunar calendar, with 13 months, that is, there is an extra leap August. At that time, there were some sayings circulating in the society, such as "Leap eight is unlucky", "Leap seven is not leap eight, and leap eight is killed with a knife", which obviously has no scientific basis. Then, why is there a leap month, and why is 1995 a leap August?
The calendar adopted in China is the perpetual calendar, commonly known as the solar calendar. The earth revolves around the sun for one year; The traditional lunar calendar in China, commonly known as the lunar calendar, takes the cycle of the moon as the unit for calculating time. The earth goes around the sun once, and the temperature changes once. So the solar calendar is 365 days a year, which is consistent with the change of hot and cold. The lunar calendar has 354 days a year, which is different from the solar calendar by 1 1 day, so it is adjusted by leap month. The error in 8 years is nearly a quarter, and the error in 16 is half a year. Setting leap month can not only accurately reflect the changes of cold and summer, but also ensure the relative stability of gas changes throughout the year.
According to the current lunar leap system, the August of the lunar calendar must include the autumnal equinox, and the September of the lunar calendar must include the first frost. If the leap August is not arranged, the first frost will appear on the first day of 10, and the vernal equinox, summer solstice, autumn equinox and winter solstice of 1996 will be pushed off. In order to avoid this situation, it is more appropriate to arrange a leap August in the lunar calendar 1995.
Leap August occurs once every 19 years, 1957, 1976, 1995 are leap August, and there will be another leap August on 20 14, 2033 and 2052. This is a reasonable arrangement in calendar calculation, and there is nothing mysterious.

What year is the birthday of people who leap in August of the lunar calendar? Great gods, help!

In the nineteenth year, the birthday of the lunar calendar has arrived, and the lunar calendar will be celebrated this year. Because I finally caught up,
How often does the lunar calendar run in August?

In what year does the next leap August appear?
Leap August occurs every 19 years. 1957, 1976, 1995 are leap August, and there will be another leap August in 2052. This is a reasonable arrangement in calendar calculation, and there is nothing mysterious.
In short, the leap month is only used to adjust the time difference between the lunar calendar and the solar calendar, which is convenient for human labor and production. Its appearance is the understanding and utilization of natural phenomena by human civilization, and has no internal connection with social phenomena and natural disasters. People should never be confused by the saying that there is a disaster in August.
Not every leap month appears once in 19, but once in 19 means that every 19 in the lunar calendar and the Gregorian calendar is the same. For example, before 19, the day in the solar calendar is X, and the day in the lunar calendar is Y, and this is still the case after19,65438+.
The following is the leap moon law
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.
