What is the solar calendar?
The Gregorian calendar year is approximately equal to the tropic year, one year 12 months. This month has nothing to do with Wang Shuo's family. The month and date of the solar calendar are very consistent with the position of the sun on the ecliptic. According to the date of the solar 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.
At present, the Gregorian calendar, which is commonly used in the world, is a solar calendar, with 365 days in a normal year and 366 days in a leap year, once every four years, once in a hundred years and once again in the 400th year, that is, there are 97 leap years every 400 years. The average length of the Gregorian calendar is only 26 seconds away from the tropic year, and it takes only one day to accumulate 3300 years.
What day of the month we usually say refers to the solar calendar; The first ten days of each month in the lunar calendar are generally called the first few days of the month (that is, the first day to the tenth day), followed by the tenth, twentieth, twentieth and thirtieth days of the month. ...
What do solar and lunar calendars mean? The Gregorian calendar is the Gregorian calendar, which is the date of a month, and the lunar calendar is the old calendar, which is the date of a month. For example, New Year's Day is a solar calendar and Spring Festival is a lunar calendar. If it helps you, please give a "favorable comment". Oh, thank you!
What does the solar calendar mean? People in China used to calculate the days by observing the changes of the moon, that is, the lunar calendar, also called the old calendar. Westerners calculate the days according to the changes of the sun, which is called the solar calendar. Now it is universal in the world, so it is also called the solar calendar.
The lunar calendar refers to the first day of each month, which belongs to the lunar calendar. What's the date of the solar calendar? 1 is the solar calendar.

What is the solar calendar? Is it the same as the lunar calendar? The solar calendar is different from the lunar calendar. At present, there are two kinds of calendars used in China: solar calendar (also called solar calendar) and lunar calendar (also called lunar calendar). The Gregorian calendar defines a year as 365 days, which is 0.2422 days shorter than the tropical year, and it is called a normal year. So the difference of four years is 23 hours 15 minutes and 4 seconds (5 hours, 48 minutes and 46 seconds ×4), which is close to 1. Add 44 minutes and 56 seconds every four years and 3 days, 2 hours, 53 minutes and 20 seconds every 400 years (44 minutes and 56 seconds × 100). So we have to add three days every 400 years. In order to facilitate the calculation, the rules of four-year leap, one-hundred-year leap and four-hundred-year leap are formulated.
At present, there are Gregorian calendar (also called solar calendar) and lunar calendar (also called lunar calendar) in use in China. According to the needs of agricultural production, the lunar calendar is adopted. The lunar calendar is sometimes1February and sometimes1March, but one month in1March is called leap month, such as leap July and leap March. It is not included in the normal month series. Because the 12 moon is 354.3672 days (29.5306× 12), which is different from the tropic year by 1 1 day, there will be 30 days more after three years, so a leap month will be added after three years to eliminate this error. If seven leap months are inserted into 19, it is almost equal to 19 tropical year, that is, 19 leap months. This discovery predates the ancient Greeks 160 years.
The solar calendar is based on the revolution of the earth around the sun, the lunar calendar is based on the moon, and the yin-yang calendar is based on both.

When is the Gregorian calendar? Gregorian calendar is a common date in modern society.
For example, today is July 16, 10, which is the same for every country. Newspapers, computers, documents, etc. All on the same day.
However, the lunar calendar is not so popular, and it is generally only used in geomantic omen, numerology and China festivals. Generally, only overseas Chinese use the date calculation method.

What does the Gregorian calendar mean? The standard name of the Gregorian calendar is the Gregorian calendar, and now it is the international calendar.
Simply put, long is the solar calendar.
The solar calendar is the abbreviation of the solar calendar, which is related to the earth's annual orbit around the sun, and has nothing to do with the moon phase. Gregorian calendar is a western calendar, not created by China, so it is also called "western calendar" (relative to China calendar).
What do Gregorian and Gregorian calendars mean? We now officially adopt the solar calendar.
traditional Chinese calendar
The lunar calendar in China, also known as the lunar calendar, should be familiar to everyone. Many traditional festivals, such as Spring Festival and Mid-Autumn Festival, are all lunar holidays. However, if you ask about the rules of the lunar calendar, I'm afraid not many people know. Most people know that the first day is the day when the new moon appears, and the day of the full moon is around 15. Many people also know the approximate date of the 24 solar terms in the solar calendar. Detailed concepts such as leap month are not well understood by most people. After some searching and reading, I finally have a certain understanding of the rules of the lunar calendar. I want to share it with you here.
First of all, the lunar calendar takes the month as the basic unit, and a month starts from the day when the new moon appears until the day before the next new moon appears. Because the period of the moon's revolution is between 29 and 30 days, a month in the lunar calendar is also 29 or 30 days from the appearance of the new moon. 30 days for the big moon and 29 days for the small moon. Unlike the solar calendar, large and small months are not fixed in different years. For example, the day before the Spring Festival is usually called New Year's Eve, but in many years, such as the 2000 lunar calendar1February, there are only 29 days. Since the period of twelve months is about shorter than that of the solar year 1 1 day, in order to keep the lunar year and the solar year relatively stable, a leap month should be added every two or three years. About every nineteen years, seven leap months will be added. The 24 solar terms are determined by the position of the earth in its orbit around the sun. Starting from the annual winter solstice, every 15 degree is a solar term. Therefore, the 24 solar terms have roughly fixed dates in each month of the solar calendar. In ancient times, the twenty-four solar terms guided farming, which is why the lunar calendar is also called the lunar calendar. Among them, the twelve solar terms in the second half of the solar calendar are also called zhongqi. The time when Qi appears is directly related to the determination of leap month.
China lunar calendar calculation has the following rules:
All new moons and solar terms are calculated according to Beijing time. At present, Beijing time is east longitude 120 degrees, which is the standard time in the East Eighth District. However, when calculating the lunar calendar time before 1929, Beijing local time, that is, east longitude 1 16 degrees 25, shall prevail. This rule is used to distinguish the China lunar calendar from other similar lunar calendars, such as the Japanese lunar calendar.
A day starts at 0: 00 pm. Although the old sub-hour is equivalent to today's 23: 00 to 1: 00, the last four hours of the sub-hour belong to the previous day, and the next four hours belong to a new day, so it conforms to the definition of a day starting from zero.
The day when the new moon appears is the first day of a month. If a solar term appears on this day, whether it appears later than the new moon or not, it will be counted as falling into the new moon.
The winter solstice always appears in 1 1 month of this year's lunar calendar.
From the second day of the winter solstice of one year to the winter solstice of the next year, if there are thirteen new moons, a leap month will be added. When a leap month needs to be added, the first lifeless month is the leap month. Because there are only twelve kinds of neutral gases, there is no possibility of neutral gases for at least one month and two months. But in this case, only the first month without breath is a leap month. When the month before leap month is a month, it is called leap month.
The lunar calendar calculation rules listed above were adopted during the Shunzhi period of the Qing Dynasty, that is, AD 1645. An important feature of the above laws is that they are completely based on astronomical observations in theory, and there is no mathematical relationship between them. This is in sharp contrast to the Gregorian calendar, which is completely determined by mathematical relations. Of course, when it comes to the calculation of the future lunar calendar, we still need the mathematical model of the movement of the moon and the earth, and the high-precision mathematical model is quite complicated. If there is no computer, it is impossible for ordinary people to calculate the accurate lunar calendar. The mathematical relationship of the solar calendar is very simple, and it is easy to calculate whether it is a leap year or not. This forms another sharp contrast.
What does the Gregorian calendar mean? Gregorian calendar is the current international calendar, also called solar calendar, commonly known as solar calendar. The solar calendar, also known as the solar calendar, is based on the fact that the earth orbits the sun once a year, which is very common in western countries, so it is also called the western calendar. Since the Revolution of 1911, China has adopted the solar calendar since the first year of the Republic of China, so it is also called the "national calendar". In order to be symmetrical with China's old calendar, it is also called "new calendar". 1949 officially stipulates the calendar year. The area of Taiwan Province Province is called A.D..
