How to distinguish the lunar calendar from the solar calendar?

Many people don't know how to distinguish the solar calendar from the lunar calendar in their lives, and they don't know what this means. I feel very puzzled. Let's take a look at how the lunar calendar distinguishes the relevant materials of the lunar calendar. Let's have a look.

How to distinguish 1 Lunar calendar and solar calendar are the same meaning, while Gregorian calendar and Gregorian calendar are the same meaning. The differences are as follows:

First, the time is different.

1, lunar calendar: the lunar calendar takes the moon's orbit around the earth as a cycle, 1 month ≈30.4369 days, 30 days for the big month and 29 days for the small month. By adding leap months, the average number of days in each year is close to the solar calendar, so as to adjust the four seasons. There is a leap month in the summer calendar about every two or three years.

2. Gregorian calendar: The earth's cycle around the sun is 1 year ≈ 365.2422 days. A year is divided into 12 months, big month 3 1 day, small month 30 days, and February only has 28 days. The mantissa of four years has accumulated to *** 1 day, and it was added in February of the fourth year, and there were 29 days in February this year.

Second, the calculation method is different.

1, Lunar Calendar: Astronomically, it mainly refers to a calendar arranged according to the phases of the moon, which is calculated by the moon circling the earth once (based on the sun, the actual moon runs more than once).

2. Gregorian calendar: the month and date of Gregorian calendar are very consistent with the position of the sun on the ecliptic. According to the date of the Gregorian calendar, we can clearly see the changes of cold and warm seasons in a year; But every month, you can't see the new moon, the new moon, the new moon.

Third, the sources are different.

1, Lunar calendar: Lunar calendar is the law of celestial movement observed by ancient Chinese. In ancient times, the era of dry branches was adopted. According to Wan Mingying, a historian of Ming Dynasty, it was invented when the dry branches were determined to be emperors according to the clear records in the ancient documents of China, and it was recorded in detail in his book "Three Rings". The invention of trunks and branches marked the emergence of the most primitive calendar, which was used to calculate the age by numbers.

2. Gregorian calendar: The earliest source of Gregorian calendar can be traced back to the Gregorian calendar of ancient Egypt. The Nile is the lifeblood of Egypt, and it is precisely because of the need to calculate the flood cycle of the Nile that astronomy and solar calendar in ancient Egypt came into being.

Seven thousand years ago, they observed that after Sirius rose at the same time as the sun for the first time, the Nile began to flood in fifty or sixty days, so they took this day as the beginning of the year and calculated that it was July of 19. The first year was set at 360 days, and later it was changed to 365 days. This is the first solar calendar in the world.

How to distinguish the lunar calendar from the lunar calendar? After the Revolution of 1911, China began to introduce the western Gregorian calendar, commonly known as "solar calendar" and "new calendar", whose names correspond to the original calendar of China. After the founding of New China, the Gregorian calendar was officially adopted.

The lunar calendar is also called the lunar calendar, which is mainly based on the law that the moon revolves around the earth.

A month in the lunar calendar is called a "new moon". The first day of each month is a new moon, and the fifteenth day is a new moon. The "new moon" is the average period of the moon's profit and loss. The so-called "full moon and sunny" means this.

Many people think that the lunar calendar is the lunar calendar, but there are still differences between the two. In fact, the ancient calendar is a kind of lunar calendar, mainly based on the lunar calendar (the moon), but it also takes into account the law of the sun's activities (the 24 solar terms), so it should be in a strict sense. The unique 24 solar terms in China calendar are an important reference for agricultural production, so people also call the lunar calendar "lunar calendar".

The lunar calendar is based on the laws of the moon and the solar calendar is based on the laws of the sun. Because the cycles of the sun and the moon can't match, this leads to a difference of about eleven days between the lunar calendar and the solar calendar every year.

If we follow the lunar calendar completely, the Spring Festival will be celebrated in summer in less than fifteen years.

But this did not happen, because there is a great invention in China's calendar called "leap setting method". Every 19 years, seven leap months are set, and the year with leap months is 383 days or 384 days, which is called leap year. For example, 20 16 and 2020 are leap years.

Traditional festivals in China are all set according to the lunar calendar.

Nowadays, people belonging to the Han cultural circle still celebrate the Spring Festival, Lantern Festival, Tomb-Sweeping Day, Dragon Boat Festival, Mid-Autumn Festival and other festivals every year.

It uses leap method to fill the time difference between the lunar calendar and the solar calendar, and uses the laws of the solar calendar to formulate the 24 solar terms for arranging farming.

In the time series of the lunar calendar, people's lives are more harmonious and consistent, and spring ploughing and autumn harvest have been planned in an orderly way.

The lunar calendar, in which the sun and the moon coincide, is actually far more practical than other calendars. It is not only a calendar, but also the embodiment of thousands of years' life experience and wisdom of China people.

How to distinguish the lunar calendar from the lunar calendar? What is the solar calendar?

The solar calendar is also called the solar calendar, and the calendar decided by the sun is the chronology of the earth's orbit around the sun, which is 1 year ≈ 365.2422 days.

This is a calendar based on the cycle of the earth's movement around the sun.

According to the date of the solar calendar, we can know the changes of the four seasons, but we can't show the moon's full and short periods, which is very inconvenient for people who need to know the tidal changes according to the moon phases.

The popular Gregorian calendar in the world today is the Gregorian calendar. It takes a tropical year as a year and then divides it into twelve months (the number of months is 3 1 day, 30 days and 29 days, all of which are manually designated), which is called the solar calendar, that is, the solar calendar.

It is made by westerners, and people in Hong Kong and Taiwan also call it the western calendar.

What is the lunar calendar?

In the lunar calendar, the moon has the final say, and the chronology with the moon circling the earth as the cycle is 65438+ 10 ≈30.4369 days.

Astronomy mainly refers to the calendar arranged according to the moon phase cycle, in which the moon orbits the earth once (taking the sun as the reference, the actual moon runs for more than one week). )

It doesn't consider the annual apparent motion law of the sun at all, so the date of the lunar calendar can't show the changes of the four seasons.

Lunar calendar is one of the traditional calendars in China, also known as lunar calendar, ancient calendar, Han calendar, yellow calendar, summer calendar and old calendar.

The difference between solar calendar and lunar calendar

The so-called lunar calendar and solar calendar are two different calendar calculations, and their reference objects are different.

The lunar calendar, which is often said, is based on the moon. People call the moon's time around the earth "lunar month", with a period of about 29.53 days. For the convenience of conversion, the big month is 30 days and the small month is 29 days.

The solar calendar is based on the sun, and the time for the earth to go around the sun is called the "solar year", which is about 365.25 days. Divided into 12 months, each month is about 30.44 days.

Because the moon is closer to the earth, it is easy to observe. Therefore, in ancient times, the "lunar calendar" was more widely used, such as eight-character fortune telling, marriage, building a house to see the sky, and the old calendar was based on the "lunar calendar".

In the folk, birthdays are basically based on the "lunar calendar", especially in rural areas, birthdays are basically calculated according to the lunar calendar; People in the city prefer birthdays in the solar calendar, but in modern times, they are not very particular about it. Even the birthdays of the lunar and solar calendars should be celebrated.

The lunar calendar is very important, but the solar calendar is not without its merits. 24 solar terms, like us, is divided according to the solar calendar.

One revolution of the earth around the sun is 360 degrees, which is divided into 24 parts on average, each part is 15 degrees. So every revolution of the earth is 15 degrees, which is a solar term.

Careful friends may observe that the time of the lunar calendar is about eleven days worse than that of the solar calendar every year. According to the lunar calendar, we will celebrate the Spring Festival in summer in less than five years. However, this did not happen. This is a kind of calendar calculation of "harmony of yin and yang" initiated by our clever ancients, which is called "Yin and Yang Calendar", which is what we often call "Lunar Calendar"!
