The difference between lunar calendar and new calendar

How to distinguish the lunar calendar from the new calendar? What is the difference? The lunar calendar is not a lunar calendar. Simply put, although the lunar calendar is also based on the northern moon, it also needs to consider the movement of the sun and the changes of the four seasons. It's a lunar calendar, not a lunar calendar. Specifically, the lunar calendar is based on the northern moon (the cycle of the moon's profit and loss). The lunar calendar calculates the moon's profit and loss cycle as one month, 650. However, the moon has a full moon, which is 29 days, 12: 44: 3, which is more than 29 days and less than 30 days. For convenience, the lunar calendar divides months into two types: big month and small month. Every month is 30 days, every two months is 29 days, and a year is 354 days. In fact, the new moon is not exactly equal to the average of the big moon and the small moon-29 days and a half, but 44 minutes and 2.8 seconds more than 29 days and a half. So 12 moon is actually 8 hours, 48 minutes and 34 seconds longer than 354 days, and it will be 1 1 day in 30 years. Therefore, a leap year 1 1 will be inserted in the 30 years of the lunar calendar, and an extra day will be added in the 12 months of each leap year. The leap year in the lunar calendar is 355 days. So every 30 years, the lunar calendar has 19 354 days and 1 1 355 days, and the average length of a year is 354 days, 8 hours and 48 minutes. Its year is almost shorter than the tropical year 1 1 day. In three years, we lost more than a month, and 17 lost more than half a year. So with this length of time, the New Year doesn't have to be spent in winter, but it can be spent in spring, summer and autumn. Its only advantage is that the shape of the moon can be inferred from every date of the lunar 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. Now all the lunar calendars are said to have been used by our ancestors as early as the Xia Dynasty (BC17th century ago). So people also call it the summer calendar. 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 its black 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. In this way, there will be 33 extra days every three years, that is, one more 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.

What's the difference between the new calendar and the lunar calendar? The new calendar is also called the solar calendar.

The solar calendar, also called the Gregorian calendar, comes from the west. For example, when calculating the constellation, it is calculated according to the solar calendar (Gregorian calendar).

The lunar calendar, also called the lunar calendar, comes from China.

For example, the Mid-Autumn Festival on August 15th, Tomb-Sweeping Day, Chinese Valentine's Day and Spring Festival are all counted according to the lunar calendar. New Year's Day, Valentine's Day (2. 14), Christmas, National Day, Army Day and the birthday of the Party are all calculated according to the Gregorian calendar.

Their main difference is that the solar calendar is international, while the lunar calendar is unique to China.

The solar calendar takes one year for the earth to make a circle around the sun. ***365 days, 5 hours, 48 minutes and 46 minutes. An average year is only an integer of 365 days, not a mantissa. The solar calendar is divided into 12 months, 3 1 day for the big month, 30 days for the small month, and only 28 days in February. It is also stipulated that before July, a single month is a big month and a double month is a small month; After August, two months are big months and one month is small months. The remaining 5 hours, 48 minutes and 46 seconds each year, there is only one day in about four years, and this day is added in February of the fourth year. This year is called leap year, so February in leap year has 29 days.

In the lunar calendar, the moon is full and short for one month, ***29 and a half days. For the convenience of calculation, the big moon is customized for 30 days and the small moon is customized for 29 days. During the period of 65438+mid-February of a year, generally, large and small months are arranged alternately. There are about 365 days in the lunar calendar year, and there is no difference between a normal year and a leap year. The lunar calendar does not consider the movement of the earth around the sun, so the changes of the four seasons in the lunar calendar have no fixed time and cannot reflect the seasons, which is a great shortcoming. In order to overcome this shortcoming, people later decided on a new calendar, which is the so-called yin-yang desk calendar. The summer calendar (also called lunar calendar or lunar calendar) still in use in China is this kind of lunar calendar. Like the lunar calendar, it customizes a month according to the time when the moon wanes, that is, 30 days in the big month and 29 days in the small month, but it also adopts the method of adding leap months to make the average number of days in a year close to that in the solar calendar to adjust the four seasons. The lunar calendar has a leap month every two or three years.

The difference between lunar calendar and solar calendar is more popular: the solar calendar is the date of a month in the calendar. That is the calendar on which you go to school, work, etc.

The lunar calendar is usually the first day of a month, or a calendar for calculating solar terms or traditional festivals.

How to distinguish Gregorian calendar, solar calendar, lunar calendar and lunar calendar? What is the lunar calendar like the lunar calendar? The full name is "Lunar Calendar". A kind of calendar. The lunar calendar used by China before the Revolution of 1911 was actually a combination of yin and yang. The characteristic of the lunar calendar is that the length of calendar months depends on the astronomical phenomena, and the average value is roughly equal to the first month of the lunar calendar, the 30th day of the lunar calendar and the 29th day of the lunar calendar. The length of the Gregorian calendar year is only an integer multiple of the Gregorian calendar month, which has nothing to do with the tropical year, and the Gregorian calendar month has nothing to do with the cold and heat of the four seasons.

Gregorian calendar: full name "Gregorian calendar". A kind of calendar. Its characteristics are: the length of the year is based on the astronomical phenomena, the average length is about equal to the tropic year, and the length of the month is artificially specified, which has nothing to do with the profit and loss of the moon phase. It is also artificial to divide a year into several months.

Lunar calendar: the old calendar of China (the lunar calendar). Twenty-four solar terms originated from the old calendar in China, which is of great significance to agricultural production, so the old calendar is often called "Lunar Calendar". Solar terms do indicate the time when the four seasons are hot and cold, but they are determined according to the position of the sun on the ecliptic, and should belong to the solar calendar in the yin-yang calendar. Therefore, the lunar calendar is the lunar calendar; As for the Gregorian calendar, it is actually the Gregorian calendar ~

What's the difference between the new calendar and the lunar calendar? The new calendar is the solar calendar.

Gregorian calendar is also called solar calendar, and summer calendar is also called lunar calendar (lunar calendar).

Its date: the former is measured by the earth's 360 degrees (one week) around the sun; The latter is based on the moon's 12 circle around the earth. The difference between the solar calendar and the lunar calendar is 7 months (lunar month) every 19 years.

In fact, our ancestors have long mastered the basic laws of the solar calendar and the lunar calendar. The twenty-four solar terms are astronomical benchmarks of the solar calendar. For example, the annual winter solstice falls on 65438+February 22nd. So we already have the experience of using the solar calendar.

So since our ancestors already knew the laws of the Gregorian calendar, why use the lunar calendar?

1, our female physiological cycle runs according to the moon;

2, the tidal cycle on the earth is according to the trajectory of the moon:

3, 19 plus 7 months is exactly the same as the two calendars;

4. Spring Festival is the biggest festival for China people, and it is also a festival of the lunar calendar.

…

Therefore, the dual calendar system in China should exist in the past, now and forever!

Our astronomical civilization should be developed in the past, present and future! Good luck! ! 1

What's the difference between the lunar calendar and the solar calendar? Calendar in China can be divided into three types: solar calendar, lunar calendar and yin-yang calendar. The solar calendar takes the annual apparent movement period of the sun (i.e. tropic year, equal to 365.2422 days) as a year, which is divided into 12 months, and has nothing to do with the movement of the moon. According to the grim date, we can know the changes of the four seasons from winter to summer, but it can't show the complete and short period of the moon, which is inconvenient for those who need to know the tidal changes according to the moon phases.

In the lunar calendar, the full moon (that is, the new moon, equal to 29.5306 days) is a month, 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, and now it has been abandoned except for the religion of * * *.

The lunar calendar is the China lunar calendar, which emphasizes the length of the solar calendar and avoids the shortness of the lunar calendar. The month of the lunar calendar is the month and the year of the solar calendar is the year, that is, the moon is the month and the tropic year is the average length of a year. Therefore, the lunar calendar is a solar calendar with lunar elements and a lunar calendar with solar elements. According to the date of the lunar calendar, we can not only know the ebb and flow of tides, but also basically grasp the changes of seasons. The lunar calendar is an original creation of our country, which shines with the wisdom of our ancestors.

The difference between the lunar calendar and the new calendar: June 3rd in the solar calendar is your birthday, and the lunar calendar birthday should be April 2nd1day.

The third day of June is your lunar birthday, and the Gregorian birthday on 20 10 is 14 July.

On the basis of the lunar birthday, the Gregorian birthday is different every year.

The difference between the lunar calendar and the lunar calendar is the lunar calendar, the solar calendar and the combined calendar of yin and yang.

Human life and production are always inseparable from time and space. How to remember, express clearly to others or even accurately record an event or phenomenon requires a fixed method, which is the problem of Gregorian year, Gregorian month, Gregorian day and Gregorian calendar.

It is easy to observe a day consisting of sunrise, sunset and day-night cycle. The longer the moon, the longer the month and the longer the year. After long-term observation, it is found that the full period and short period of the moon (the first month of the lunar calendar) are about 30 or 29 days, and the seasonal period (the tropic year) is about 365 or 366 days. If we don't follow these standards, but take the orientation of the sun and the moon in the stellar background of the celestial sphere as the standard, then in astronomy, there are also sidereal months (shorter than the moon) and sidereal years (slightly older than the regression). Others include the near-point month and the intersection month, so I won't talk about it here.

Year, month and day are endless cycles. Originally, there was no beginning or end, but for convenience, people always designated a beginning. Different nationalities, different regions and different times have different regulations, so the problem of mutual conversion between the beginning of the year and the beginning of the month arises.

There are several ways to calculate the beginning of a day, such as dawn, pingdan, sunset and midnight.

There are several ways to calculate the beginning of a month, such as starting from the full moon and starting from the appearance of the new moon.

At the beginning of a year, there are many calculation methods, such as winter solstice, vernal equinox, and other signs.

The most troublesome problem is that a new moon is not exactly thirty days, but a little over twenty-nine and a half days. But in real life, we can't divide a day into two halves, so that the upper part belongs to last month and the lower part of the same day belongs to the next month. That's too inconvenient. If 365 days of a year are defined as 12 months ***354 days, there is still 1 1 day left. There is no common multiple between 29.5309 days of the moon and 365.2422 days of the Tropic of Cancer, so a cycle cannot be formed. What should we do?

It is precisely because of the different ways to deal with these problems that various calendars have appeared in the world. To sum up, there are only three kinds: lunar calendar, solar calendar and combined calendar of yin and yang. The first two only care about one end, and the third is to take care of both ends.

Let's talk about the lunar calendar first. Simply put, it is based on the cycle of the moon. The so-called "simplicity" means only caring about the moon, regardless of seasonal changes such as climate change caused by the relationship between the sun and the earth. The moon is also called "lunar calendar", so this calendar is called "lunar calendar" for short. When the moon and the sun are just on both sides of the earth, the soft moonlight shines on the sleeping earth all night. The most round moment of the moon is called "full moon", also called "looking". Because the moon is always in motion; Therefore, strictly speaking, the real "lookout" is only a very short moment. For an instant, ordinary people can't observe such subtle changes. Usually, the whole day including the real "lookout" is called "lookout" day, or simply "lookout", which is the most obvious astronomical phenomenon that can be easily observed. On the contrary, when the moon is between the sun and the earth, people can't see any images of the moon at all. This day is called "New Moon". Astronomy refers to the moment when the longitude of the ecliptic of the moon coincides with the longitude of the ecliptic of the sun. Astronomers call the period of moon phase change, that is, the length of time from new moon to new moon or from looking to looking, "Shuowangyue", and the Tibetan calendar is called tshes-zla, which can also be translated as "lunar month". Many years' observation shows that the length of Wang Shuo's moon is not fixed, and its average length is 29 days 12 hours and 44 minutes, that is, 29.5306 days, which is very important data for making calendars and must be firmly remembered. It can be roughly recorded as 29 and a half days.

? The most typical lunar calendar is the "monthly calendar" in the * * * calendar (different from the "palace calendar" used in agriculture), which was called "* * * calendar" in ancient China. It always takes 12 lunar months as a year, with an average of 29.5 days per month, and 12 ***354 days. At the end of leap year, 355 days plus 10 days, and there is no leap month.

? In addition, we know that human life and production, especially in temperate regions of the earth, are closely related to the climate change of warm spring, hot summer, cool autumn and cold winter. This year consists of four seasons: spring, summer, autumn and winter. It is called "tropic year", that is, the cycle of the sun from highest to lowest, and then from lowest to highest ... >>
