What is Lunar Calendar? What is the Gregorian calendar?

The Gregorian calendar is not the same as the lunar calendar. There are two kinds of Gregorian calendar (also called the solar calendar) and the lunar calendar (also called the lunisolar calendar) currently used in China The Gregorian calendar sets the year as 365 days, which is 0 2422 days shorter than the return year, which is called a common year In this way, the difference between 4 years will be 23 hours and 15 minutes and 4 seconds (5 hours, 48 minutes and 46 seconds 4), close to one day, add this day to February, and the year is 366 days, which is called a leap year But in this way, every 4 years an extra 44 minutes and 56 seconds are calculated, and every 400 years will be counted an additional 3 days, 2 hours, 53 minutes and 20 seconds (44 minutes and 56 seconds 100), so every 400 years should be added 3 days less for the sake of calculation"There is a leap in four years, no leap in a hundred years, and a leap in four hundred years"provisions

China currently uses the Gregorian calendar (also known as the solar calendar) and the lunar calendar (also known as the lunar calendar) according to the needs of agricultural production in China, the use of the lunar calendar The lunar calendar is sometimes 12 months in a year, sometimes 13 months, but one of the 13 months is called a leap month, such as leap July, leap March, etc., which is not counted in the normal month sequence Because the 12 synodic months are 354 3672 days (29 5306 12), a difference of 11 days from the return year, and a difference of more than 30 days after 3 years, Therefore, after 3 years, a leap month will be added to eliminate this error, so that there will be 13 months in this year In the era of the Northern and Southern Dynasties in China, astronomer Zu Chongzhi found that if 7 leap months are inserted in 19 years, it will be almost equal to 19 return years, which is 19 years and 7 leaps This discovery is more than 160 years earlier than the ancient Greeks

The revolution of the earth around the sun is called the "solar calendar", the moon is mainly based on the "lunar calendar", and the combination of both is called the "lunisolar calendar".

Calendar trivia.

Lunar calendar: Based on the cycle of the moon orbiting the earth, the "lunar calendar" is commonly referred to as the old Chinese calendar. The characteristics of the lunar calendar are:

The length of the calendar month depends on the celestial phenomena, and the average is roughly equal to the synodic month, the 30th day of the major month, and the 29th day of the minor month. The length of the calendar year is only an integer multiple of the calendar month, and has nothing to do with the return year, and the calendar month has nothing to do with the cold and heat of the four seasons. ......

Lunar calendar: A type of calendar. There are 12 months in a normal year, 30 days in the big month, 29 days in the small month, 354 days or 355 days in the year (which month is big in the year, which month is smaller, and the year is different), and there are seven leap months in the nineteenth year, and there are 383 or 384 days in the year with the leap month.

According to the position of the sun, a solar year is divided into 24 solar terms, which is convenient for farming. The year is matched with the heavenly and terrestrial branches, and the cycle repeats itself over and over again for sixty years. This kind of calendar is said to have been founded in the Xia Dynasty, so it is also called the Xia calendar.

Also called the "Old Calendar".

Gregorian calendar: What is the solar calendar? It is based on the apparent cycle of the sun, that is, the cycle of the earth's movement around the sun, so it is called the solar calendar, or simply the solar calendar.

The Gregorian calendar is also known as the Gregorian calendar, and it is internationally applicable. The solar calendar is based on the time it takes for the earth to make one revolution around the sun, with a total of 365 days, 5 hours, 48 minutes and 46 seconds. In ordinary years, only the whole number of 365 days is counted, and the mantissa is not counted; The year is divided into 12 months, with 31 days in the big month, 30 days in the small month, and only 28 days in February.

The mantissa of the four years accumulates for a total of one day, and when added to February of the fourth year, this year is called a leap year. So February in leap years has 29 days.

Summary: The pure lunar calendar does not set a leap month, while the Tibetan calendar and the lunar calendar have a leap month, although the common year is also 354 or 355 days, and the year with a leap month is 384 days, so it cannot be said that the lunar calendar is a lunar calendar, and the Tibetan calendar is not a lunar calendar, but a lunisolar calendar.

The "lunar calendar" used in China before the Xinhai Revolution was actually a lunisolar calendar.

The Gregorian calendar is the universal calendar, also known as the Gregorian calendar. (No. 1, No. 2...) No. 30, No. 31).

The lunar calendar is what we usually call the lunar calendar. (Beginning.)

First, the beginning. Nine, ten.

5. 30) The main basis for the earth's revolution around the sun is called the "solar calendar", and the main basis for the moon's waxing and waning is called the "lunar calendar".

Our traditional Chinese festivals are based on the lunar calendar. (For example, the first day of the first lunar month is the Spring Festival; The fifteenth day of the first lunar month is the Lantern Festival; February 2, commonly known as the dragon raises its head, the Green Dragon Festival; March 3 is the Qingming Festival; May 5 is the Dragon Boat Festival; July 7 is the Qixi Festival; July 15 is the Midyear Festival; August 15 is the Mid-Autumn Festival; September 9 is the Chung Yeung Festival; December 8 is Laba Day; The 23rd day of the lunar month is the day of the ritual stove, which is commonly known as "the small year").

It is a pity that for a long time, some well-known people do not understand the characteristics of the dual-track system of the lunar calendar, and the strength of Western European civilization has a prejudice against the lunar calendar, and the practice of emphasizing the Western calendar and passing through the Chinese calendar (including the calendar of other ethnic minorities in China), and emphasizing the solar calendar and the lunisolar calendar is very detrimental to the inheritance of the Chinese 5,000-year-old astronomical calendar culture, and is affected by this and does not write the lunar calendar into the teaching plans of primary and secondary schools, and finally makes this excellent astronomical calendar completely forgotten by the next generation, which is very sad. It is the sorrow of the Chinese nation.

The lunar calendar is one of the few astronomical calendars in the world today with a yin-yang dual-track system or even a multi-track system (such as the reflection of the five-star orbital cycle such as the Venus cycle), and it is the only calendar in the world that uses the most advanced astronomical data and theoretical calculations, and is the most thorough calendar to fix the weather. It is hoped that the vast number of Chinese people will pass on this calendar.

The lunar calendar is a lunisolar calendar (mixed calendar) in which the average month is equal to one synodic month, but a leap month is set to make the average calendar year a return year, and 24 solar terms are set to reflect the changing characteristics of the seasons (the annual movement of the direct point of the sun), so it has elements of the solar calendar. 19 years and 7 leap months.

The Gregorian calendar, a Western legislation that turns the revolution of the earth into a year of return. According to the Julian calendar, there is one leap year every four years, with 366 days in leap years and 365 days each in the remaining three years (called common years). The number of years in the Common Era that can be divided by 4 is a leap year.

The average length of the Julian calendar in one year is 11 minutes and 14 seconds longer than the actual revolution period, that is, about 3 days per 400 years. Later, there was a modification, and the whole hundred should be divisible by 400, which is a leap year.

1. Gregorian calendar - a calendar based on the earth's rotation around the sun as a year.

2. Lunar calendar - a calendar based on the aetheric lunar (moon) orbiting the earth for one month and 12 months for one year (13 months for leap years). (The fourth hour of the year is adjusted by leap month).

3. Gregorian calendar - the calendar used by all countries in the world. It is the solar calendar, that is, the solar calendar.

4. Xia calendar - the calendar used in the Chinese dynasties, starting from the Xia Dynasty, so it is called. It is a lunar calendar, which has been constantly revised throughout the dynasties, and later after adding 24 solar terms, it has become a lunisolar calendar.

5. Lunar calendar - no different from the summer calendar. The calendar is for farming, so the Chinese call it the lunar calendar. 24 of them

The solar terms are divided into 24 equal parts of the solar year, which is part of the solar calendar. The month and day of the lunar calendar and the leap method belong to the lunar calendar, and when they are compiled together, they become a luni-solar calendar. We don't usually pay attention, but we are used to it"Lunar calendar"No distinction.

The lunar calendar is the traditional Chinese calendar, and the solar calendar is used all over the world.

The Gregorian calendar is called the Gregorian calendar, and the Arabic numerals and the concept of the day of the week on the calendar are both Gregorian calendars, which are foreign calendars.

The lunar calendar is called the lunar calendar, the Year of the Ox, the Year of the Pig, and the first month of the first month, the twenty-four solar terms, or something, which is the lunar calendar, which is the calendar created by our ancestors.

The lunar calendar is the lunar calendar, and the solar calendar is the solar calendar.

The lunar calendar is a lunisolar calendar: its years are divided into ordinary years and leap years. Twelve months in a normal year; Leap years are thirteen months. Months are divided into major months and minor months, with the major month having 30 days and the minor month having 29 days, and its average calendar month is equal to one synodic month.

The lunar calendar is a lunisolar calendar that incorporates elements of the solar calendar on the basis of the lunar calendar (summer calendar). Taking the change period of the moon phase, i.e., the synodic month as the length of the month, adding the "24 solar terms" component of the dry branch calendar, referring to the length of the solar return year as the year, and setting the leap month to adapt the average calendar year to the return year.

Therefore, the lunar calendar has both lunar and solar elements. Unlike the Gregorian year, which is fixed at 365 or 366 days, the number of days in the lunar year is sometimes one month different from that before the solar calendar.

The Gregorian calendar is the Gregorian calendar era used in the world. On September 27, 1949, the First Plenary Session of the Chinese People's Political Consultative Conference designated the first day of the first month of the Gregorian calendar, the Gregorian calendar, as New Year's Day, by using the Gregorian calendar era commonly used in the world. Because the first day of the first lunar month is usually around the beginning of spring, the first month of the first lunar month must be the "Spring Festival".

Introduction to the lunar calendar:The lunar calendar is one of the traditional Chinese calendars, also known as the old calendar, the Han calendar, the ancient calendar, etc., after the Xinhai Revolution, the Western solar calendar (Gregorian calendar) was used, and the modern name of the lunar calendar belongs to the lunisolar calendar.

In the traditional Chinese calendar, the lunar calendar mainly refers to a calendar arranged according to the changes in the lunar phase cycle of the moon, that is, a calendar that uses the synodic month as the basis for determining the calendar month, and the year is twelve calendar months. In the process of the development and evolution of the calendar, it was combined with the 24 solar terms in the Ganzhi calendar to form the lunar calendar (Han calendar), which was used to scientifically guide agricultural production. Although the lunar calendar and the lunar calendar are commonly known as the ancient calendar, the Han calendar, and the old calendar, there is a difference between the lunar calendar and the lunar calendar (Han calendar), and the traditionally used lunar calendar (Han calendar) is actually a lunisolar calendar, not a lunar calendar in the traditional sense.

The lunar calendar is a calendar set based on the apparent motion of the moon, called the "solar calendar", referred to as the "lunar calendar", which is inherited by East Asian countries; The Gregorian calendar refers to the Gregorian calendar; The calendar set up on the basis of the sun's apparent movement, called the "solar calendar", referred to as the "solar calendar", is now commonly used in the world is this kind of calendar, because it is the West, it was transmitted to China during the Xinhai Revolution, so it is also called the new calendar.

Gregorian calendar (Gregorian calendar): Nowadays, the internationally accepted calendar, the Gregorian calendar, is mainly used. It is based on a solar return year as a year, and then divided into 12 months (the number of months has 31 days, 30 days, and 29 days, all of which are artificially prescribed), and it is called the solar calendar, that is, the solar calendar.

The Gregorian calendar has 365 days in a common year and 366 days in a leap year.

Lunar calendar (lunar calendar): The lunar calendar is the traditional calendar of our country, and there are names such as the lunar calendar, the Chinese calendar, the summer calendar, the Han calendar, the national calendar, etc., but the lunar calendar is not a lunar calendar, but a lunisolar calendar, taking the change cycle of the moon phase, that is, the synodic month as the length of the month, referring to the length of the solar return year for the year, by setting the 24 solar terms and the leap month to adapt the average calendar year and the return year.

The lunar calendar is also called the old calendar, which is the calendar that farmers attach the most importance to, because it contains eight hexagrams, 24 solar terms, 72 celestial phenomena, 9 fixed palaces, 27 changes, and 81 meteorology! This is the vane of farmers' cultivation and rest! The Gregorian calendar, also known as the new calendar, is the latest standard point for modern time!

For example, December 20, 2007 is the new calendar, the solar calendar, and the corresponding day: November 11 of the year of Dinghai is the old calendar, lunar calendar, and lunar calendar!

The lunar calendar is the lunar calendar, and the solar calendar refers to the Gregorian calendar.

The time is different: the lunar calendar is twelve months of a normal year, and the annual duration is 354 or 355 days. The Gregorian calendar has 365 days in a normal year and 366 days in a leap year, with a leap year every four years.

The number of days is different: the length of the calendar month is determined by celestial phenomena, with the big month being the 30th day and the small month being the 29th. The Gregorian calendar has 31 days for the big month and 30 days for the minor month, and the special number of days in February is 28 days in ordinary years and 29 days in leap years.

The lunar calendar is commonly known as the lunar calendar, and the usual name is the beginning of the month as the day of a certain month, such as: the beginning of September.

Eighth, the beginning. 9. The tenth day of the first month; Mid-month: September.

Ten. V.XVI; At the end of the month, the third day of September is the tenth hidden reputation, and the word "day" is not added after the title. The Gregorian calendar, also known as the Gregorian calendar, is usually called a certain day of a certain month, such as: March 12, April 20, May 31, the time must follow the word "day".

How to distinguish between the lunar and solar calendars on the calendar:

The lunar calendar is the lunar calendar, and the solar calendar refers to the Gregorian calendar. On the Li Xiedou calendar, Arabic numerals indicate the date of the solar calendar, and Chinese characters indicate the date of the lunar calendar. The solar calendar passes relatively quickly, whereas the lunar calendar passes more slowly.

For example, the 19-year solar calendar'January 1 is called New Year's Day, also known as the solar year, and the lunar calendar has just arrived on November 26.

The Namo calendar legally used by the People's Republic of China is the Gregorian calendar (solar calendar), which is the calendar used in most countries in the world. Therefore, the date of birth on the ID card is the solar calendar, and the certificate of the date of birth issued by the hospital is also the solar calendar. In other words, the day of birth is the day of the month, not the day of the first month of the lunar calendar (lunar calendar).

It's nothing, it's yin and yang and beauty.

It's not a lunar calendar.

The traditional Chinese calendar also has names such as the Chinese calendar, the summer calendar, the Chinese calendar, and the Chinese calendar. The lunar calendar is not a simple lunar calendar, but a combination of yin and yang. Taking the lunar month as the length of the month, plus the "24 solar terms" of the calendar, and referring to the length of the solar return year, the average calendar year is adapted to the return year by setting a leap month.

The lunar calendar is a calendar based on the Chinese calendar (lunar calendar) and combined with the elements of the solar calendar. So strictly speaking, the Chinese lunar calendar should not be called a lunar calendar, but a luni-solar calendar.

Related content: The first month of the lunar calendar is customarily referred to as the first lunar month. The November and December months of the lunar calendar are called the winter moon and the wax moon respectively, but the winter moon is rarely used. This is where the idiom "harsh winter" comes from, meaning that October, November, and December are the coldest months of the year.

The first ten days of the first lunar month are customarily called the first day of the first lunar month, such as the second day of the first lunar month is called the second day of the first lunar month; The eleventh to twentieth day and the thirtieth day are used directly, such as the fifteenth day of the first lunar month (Lantern Festival) is called the fifteenth day of the first lunar month.

The twenty-first to twenty-ninth days are customarily referred to as the twentieth day in order, and some experts call them anniversaries. For example, the twenty-second day of the first month is known as the twenty-second day of the first month or the second anniversary. Each month of the lunar calendar has a different nickname.

Because it is closely related to agricultural production, almost all of the months from February to September are represented by plants. The following is another name for the twelfth month of the lunar calendar.
