What do Gregorian calendar and lunar calendar mean?

What are the meanings of lunar calendar, lunar calendar, solar calendar and Gregorian calendar, and how to distinguish them? The lunar calendar is the lunar calendar, and the solar calendar even refers to the Gregorian calendar; (2) calendars based on the apparent movement of the sun are called "solar calendar" or "solar calendar" for short, and are now widely used in the world. Because it originated in the west and was introduced to China only during the Revolution of 1911, it is also called the new calendar. Today's Gregorian calendar is April 15(3), which is based on the apparent motion law of the moon. It is called "lunar calendar", or "staring calendar" for short. This is handed down from East Asian countries. Today is the thirteenth day of the third lunar month.

What does the Gregorian calendar mean? Lunar calendar, which is completely based on the cycle of the moon. The so-called "simplicity" means that it only cares 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 "full moon". Because the moon is always in motion; Therefore, strictly speaking, the real "lookout" is only a very short moment. In an instant, ordinary people can't observe such subtle changes. Usually, the whole day, including the real "observation", is called "observation" day, or simply "observation", which is the most noticeable 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". In astronomy, it 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 the moon phase change, that is, the length of time from new moon to new moon or from looking to looking, "Shuowang Moon", which is called tshes-zla in Tibetan calendar and can also be translated as "Moon". 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 a very important data for making calendars and must be firmly remembered. Initially, it can be roughly recorded as 29 and a half days.

The solar calendar is based on the apparent movement period of the sun, that is, the movement period of the earth around the sun, so it is called the solar calendar, or simply the solar calendar. Every calendar year is similar to the tropic of cancer, and the month and date in each calendar year are very consistent with the position of the sun on the ecliptic. For example, the vernal equinox is always on March 2 1 or 22, and it won't make much difference. Since the twelve divisions of a tropical year are about 30 and a half days (30.4368 days), which is equivalent to two moons, the solar calendar divides a year into twelve months. In fact, the so-called "moon" in the solar calendar is just an empty name that has nothing to do with the moon, and it has nothing to do with the moon's changing cycle. According to the date of the solar calendar, we can't know the first and second chords of the moon, but according to the month of the solar calendar, we can see the changes of the four seasons more accurately than the combined calendar of Yin and Yang.

Also, the lunar calendar is the lunar calendar ~

What does the Gregorian calendar mean? Is the Gregorian calendar a lunar calendar (lunar calendar, old calendar, ancient calendar, summer calendar)?

Gregorian calendar (new calendar, national calendar, western calendar, solar calendar),

What does the new calendar mean, lunar calendar or solar calendar? The new calendar is Gregorian calendar.

What do you mean by solar calendar and lunar calendar? The Gregorian calendar is the Gregorian calendar, not the date of the month, and the lunar calendar is the old calendar, not the date of the month. For example, New Year's Day is a solar calendar and Spring Festival is a lunar calendar. If it is helpful to you, please give a "favorable comment". Oh, thank you!

What do Gregorian and Gregorian calendars mean? We now officially adopt the solar calendar.

traditional Chinese calendar

Everyone should be familiar with the lunar calendar in China. 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 dates of the 24 solar terms in the solar calendar. Detailed concepts such as leap month are not understood by most people. After some searching and reading, I finally have a certain understanding of the laws 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 away from the appearance of the new moon. The big moon is 30 days and the small moon is 29 days. 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. Because the period of twelve months is about 1 1 day shorter than that of the solar year, in order to keep the lunar year and the solar year relatively stable, a leap month needs to 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 winter solstice every year, 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 occurrence time of geogas 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 time before the lunar calendar 1929, the local time in Beijing, 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 regarded 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 day of 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 neutral gases, there is no neutral gas for at least one month, and there is also the possibility of no neutral gas for two months. But in this case, only the first month without gas is a leap month. When the month before a leap month is a month, it is called a leap month.

The lunar calendar calculation rules listed above were adopted during the Shunzhi period of the Qing Dynasty, namely 1645. An important feature of the above rules 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, the mathematical model of the moon and the earth's movement is still needed, 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. This forms another sharp contrast.

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 known as 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, Tomb-Sweeping Day, Chinese Valentine's Day and Spring Festival on August 15 are all calculated 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. A total of 365 days, 5 hours, 48 minutes and 46 minutes. The average year is only an integer of 365 days, excluding the mantissa. The solar calendar is divided into 12 months each year, with 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 is a big month and one month is a small month. The remaining 5 hours, 48 minutes and 46 seconds each year, only about one day in four years, which was 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 wanes once a month for 29 and a half days. For the convenience of calculation, the big month is customized for 30 days, and the small month is customized for 29 days. In the middle of 65438+February of a year, large and small months are generally 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 is full and short, that is, 30 days in the big month and 29 days in the small month, but it also uses 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.

What do lunar calendar, solar calendar, lunar calendar, Gregorian calendar and AD mean? Lunar and lunar calendars

The calendar in China is a kind of lunar calendar, which is usually called the lunar calendar. Normal year 12 months, 30 days in the big month, 29 days in the small month, and 354 or 355 days in the whole year (which month is older and which month is younger varies from year to year). Since the average number of days per year is about 1 1 day worse than that of the solar year, there are 7 leap months in 19, and there are 383 or 384 leap months in a year. According to the position of the sun, a solar year is divided into 24 solar terms, which is convenient for farming. Chronology is matched with heavenly stems and earthly branches, and it is a cycle of 60 years. According to legend, this kind of calendar was founded in the Xia Dynasty, so it is also called Xia Calendar and Old Calendar. Therefore, the lunar calendar is a kind of lunar calendar.

Gregorian calendar and solar calendar

The current Gregorian calendar was formulated by Italian doctor and philosopher aloysius Lilius when he reformed julian calendar, and was promulgated by Pope Gregory XIII on 1582. The solar calendar is a kind of solar calendar, which was officially adopted in China in 19 12, replacing the traditional lunar calendar in China, while the traditional calendar in China is a kind of solar calendar, so the solar calendar is also called solar calendar, western calendar and new calendar in Chinese. Like julian calendar, the Gregorian calendar has a leap day at the end of February every four years, but the Gregorian calendar specifically stipulates that all century years (divisible by 100) have no leap day; Therefore, every 400 years, there are only 97 leap years in the Gregorian calendar, which is 3 leap years less than that in julian calendar. The average length of Gregorian calendar is 365.2425 days, which is close to the average tropical year of 365.2438+09 days, that is, the error is about 1 day every 3300 years, and it is also closer to the tropical year of vernal equinox of 365.24237 days, that is, the error is about 1 day every 8000 years. In julian calendar, the calendar year is 365.25 days, and the error is one day every 128 years. At 1582, the vernal equinox of julian calendar (March 2 1 day) is 10 day different from the actual time when the earth revolves to vernal equinox. Therefore, when the Gregorian calendar is implemented, it is also stipulated that the day after julian calendar 1582 and 10 is Friday, and 1582 and 15, that is, 10 days, are deleted, but the original cycle remains unchanged. The Gregorian calendar follows the calendar of julian calendar. Since the traditional year of Jesus' birth, it has been called "AD" or "AD".

Main differences between Gregorian calendar and lunar calendar

The lunar calendar, also known as the lunar calendar, takes one month for the moon to circle the earth, that is, 29 days 12 hours, 44 minutes and 3 seconds, and its twelve months in a year are 354 days.

The Gregorian calendar, also called the Gregorian calendar, takes 12 months as a year, which means 365 days, 5 hours, 48 minutes and 46 seconds as a year. In China, the lunar calendar is not a pure lunar calendar, but a calendar that combines the lunar calendar and the Gregorian calendar. Because the difference between the lunar calendar and the Gregorian calendar is about 65,438+065,438+0 days a year, in order to coordinate them, the leap month method is implemented, that is, 19 leap seven times a year.

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 revolves around 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 the "new calendar". 1949 officially stipulated the calendar year.
