The difference between the Gregorian calendar and the lunar calendar is silly unclear

In fact, there are three types of calendars, the solar calendar, the lunar calendar and the lunar calendar. The Gregorian calendar, also known as the Gregorian calendar, calculates time based on the period of the earth's orbit around the sun, while the lunar calendar measures time based on the period of the moon's rotation around the earth. The lunar calendar is a hybrid calendar, which is between the solar and lunar calendars, and adjusts for errors through the 24 solar terms and intercalation, which can be said to be the most accurate calendar, which is very suitable for agricultural countries like China.

The Gregorian calendar is the first day of January, and the lunar calendar is the first day of the first month of January.

The solar calendar, also known as the "solar calendar", is a calendar based on the cycle of the earth's revolution around the sun. The solar calendar year is similar to the return year, with twelve months in a year, but has no real relationship with the "synodic month". The month and day of the solar calendar also perfectly match the position of the sun above the ecliptic.

According to the records of the solar calendar, we can clearly and unambiguously see the obvious changes in the four seasons of the year, but we cannot see the changes in the two strings of the moon in each month.

The Gregorian calendar that is now common in the world is a kind of solar calendar, and China began to adopt the Gregorian calendar after the Xinhai Revolution, and after the founding of the People's Republic of China, it officially adopted the AD chronology.

The lunar calendar is a traditional calendar in China, also called "yellow calendar", "ancient calendar", "old calendar" and so on. Its calculation period is mainly calculated according to the wax and fall of the moon, with the cycle of the moon revolving around the earth as one month, and then twelve calendar months as a year.

A month in the lunar calendar can be called a "synodic month", that is, the first day of each month is the new day, the fifteenth day is the sun, and the "synodic month" is the average period of the moon's phases.

Is the lunar calendar the same as the lunar calendar? In fact, the two should not be confused. Because the lunar calendar in China since ancient times is a lunisolar calendar, it is to take the cycle of the change of the moon phase, add the "24 solar terms" of the stem branch, and then refer to the solar return year as the length of the year, and make their average calendar year consistent with the cycle length of the return year by adding leap months.

The number of days in the lunar calendar differs from the lunar calendar by about eleven days per year. So if we follow the lunar calendar, in less than five years, we will celebrate the first day of the new year in the summer. The reason why this did not happen is that there is a very clever method in our calendar, that is, the "intercalation method".

The intercalary method has 7 leap months every 19 years, so that in a year with a leap month, there are as many as 383 or 385 days. In such a setting, people's lives are more harmonious, and even spring planting and autumn harvesting can be carried out in a step-by-step and orderly manner, and such a practical calendar is the embodiment of ancient and modern human life experience and wisdom.

2. Lunar calendar = lunar calendar, which is the date used for farming in ancient China, that is, the date indicated by the small print below the calendar. The algorithm is different: the Gregorian calendar is a calendar based on the Earth's rotation around the Sun as a year.

The lunar calendar is a calendar based on the 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. The lunar calendar is a kind of calendar that integrates the elements of the solar calendar on the basis of the lunar calendar.

4. The lunar calendar is a lunar calendar, also known as the lunar calendar, which is formulated according to the law of the moon's rotation around the earth. The moon orbits the earth once in January, that is, the synodic month is used as the basis for determining the calendar month. The lunar month is called the "synodic month".

The first day of each month is the new day, and the fifteenth day is the looking day, and the "synodic month" is the average cycle of the moon's phases. The lunar calendar only cares about the synodic month, regardless of the return year, so it has nothing to do with the four seasons of the year.

5. The solar calendar is the solar calendar, which is a calendar formulated on the basis of the movement cycle of the earth around the sun. There are 12 months in a year, and this "month" actually has nothing to do with the synodic month, and the month and date are in good agreement with the position of the sun on the ecliptic, and the changes in the four seasons can be clearly seen in the year.

Lunar calendar (solar calendar): China's lunar calendar does not belong to this category, but people are used to calling the lunar calendar in life. Take the waxing cycle of the moon (i.e., synodic month, equal to the sun) as one month, and the accumulation of 12 months as one year.

It does not take into account the annual apparent motion of the sun, so the date of the lunar calendar does not show the four seasons of cold and warm. The practical value of this calendar is so small that it is now discarded except in Islam.

There is no difference between the Gregorian calendar and the Gregorian calendar, the Gregorian calendar is the current solar calendar, the Gregorian calendar is based on the earth's movement cycle, and the Gregorian calendar is a calendar system that is identified by scientists and is most closely related to the number of days of the year that is formulated. What is the difference between the Gregorian calendar and the Gregorian calendar, there is no difference between the Gregorian calendar and the Gregorian calendar, they are both internationally applicable, but the people who do not disperse the same name for it are different.

1. The internationally used calendar is the Gregorian calendar and the solar calendar, and the lunar calendar is the traditional Chinese calendar, which has become the summer calendar since the beginning of the Xia Dynasty.

2. The Gregorian calendar is also the Gregorian calendar, exactly the same statement, the full name of the Gregorian calendar is called the solar calendar, which refers to the time when the earth revolves around the sun.

3. The lunar calendar is a calendar adapted by the great ancient working people of our country according to the solar calendar and added 24 solar terms.

4. The Gregorian calendar is the solar calendar, which is the date used in the world, that is, the date we usually use to dig the core, and it is a calendar set by the earth around the sun for a year.

1. Different nature: the Gregorian calendar is the solar calendar, which is the universal date in the world; The lunar calendar belongs to the lunisolar calendar, which is the traditional farming date in China.

2. Different algorithms: the Gregorian calendar is a calendar based on the cycle of the earth around the sun; The lunar calendar is based on the cycle of the moon around the sun, and also refers to the calendar established by referring to the year of the sun's return.

3. Different categories: the Gregorian calendar is used to record dates, and the lunar calendar also includes the time of farming and rest, deriving the 24 solar terms.

Most of the world's calendars have a lunar calendar followed by a solar calendar. After China adopted the Gregorian calendar in 1912, people used to call the Gregorian calendar the solar calendar, and the traditional "lunar calendar" as the lunar calendar.

The Gregorian calendar is also known as the solar calendar, the new calendar, the Western calendar, and the Gregorian calendar. The calendar, introduced in 1582 by Pope Gregory XIII, is now the most common calendar in the world.

1.The nature is different: The lunar calendar is a lunisolar calendar.

The lunar cycle of the lunar calendar is used as the basis for the calendar month, and the time of the year is calculated according to the solar return cycle. The lunar calendar, like the lunar calendar, is based on the cycle of the moon's waxing and waning, with the first day of each month being the new day, the fifteenth day being the day, and the date between the two new days being the month.

The Gregorian calendar is a solar calendar, which is based on the solar return cycle as a year, and then divides the year into twelve months.

2.The number of days varies: The lunar calendar has the 30th day of the big month and the 29th day of the small month.

A year is set to be 12 months and 354 days. Compared to the Gregorian calendar, there is a difference of about eleven days per year. There are 7 leap months in every 19 years, and the year with a leap month has 384 or 383 days in a year, which is called a leap year.

Each month of the Gregorian calendar is divided into 30, 31, 28 or 29 days, and in some years it is 366 days, which is called a "leap year"; Some years are 365 days long and are called "common years". Generally, there is a "leap year" every four years.

3.The age of use is different: The Gregorian calendar is divided into A.D. years, after BC; The lunar calendar uses the Jiazi year, which is reincarnated every 60 years.

4.The scope of use is different: The Gregorian calendar is used in most countries; The lunar calendar is used by a few countries such as China.

The ancient Chinese calendar is actually a lunisolar calendar, commonly known as the lunar calendar. It uses the lunar phase cycle as the basis for the calendar month, and calculates the time of the year according to the solar return year cycle. It is characterized by the fact that the length of the month is determined by the phase of the moon, and the length of the year is only an integer multiple of the calendar month, and has nothing to do with the solar return year.

The lunar calendar also divides the year into 24 solar terms according to the position of the sun, which is convenient for arranging agricultural production. The practical value of the lunar calendar, which is conjunct the sun and the moon, far exceeds that of other calendars in the fields of agriculture and culture.

Today, Chinese still celebrate traditional festivals such as the Spring Festival, Dragon Boat Festival, and Mid-Autumn Festival according to the lunar calendar. According to this calculation, there will be a leap month in 2262, and there will be two Spring Festivals and two long holidays.

1. The Gregorian calendar is called the "Gregorian calendar". The lunar calendar is also called the "lunar calendar".

2. The calculation method is different. The Gregorian calendar counts a year based on the time the Earth orbits the Sun. Its length is three hundred and sixty-five days, five hours, forty-eight minutes and forty-six seconds.

Since it is not an integer, in order to level out the length, some years are 366 days, which is called "leap years"; Some years are 365 days and are called "common years". The lunar calendar is based on the cycle of the moon's waxing and waning, known as the synodic months.

3. The number of days in a year is different, and the length of the solar calendar is 365 days, 5 hours, 48 minutes and 46 seconds. Since it is not an integer, in order to level out the length, some years are 366 days, which is called "leap years"; Some years are 365 days and are called "common years". The main features of the lunar calendar are:

The length of the calendar month is determined according to the celestial phenomenon, that is, the phase of the moon, with the 30th day of the big month rotting and the 29th day of the small month.

4. The scope of use is different. The Gregorian calendar is a calendar used by all countries in the world. , which is the solar calendar, that is, the solar calendar. The lunar calendar is the calendar used by all Chinese dynasties. It began in the Xia Dynasty, so it is called the lunar calendar, and it has been constantly modified in successive dynasties, and later after adding 24 solar terms, it has become a lunisolar calendar.

The main one is that the Gregorian calendar defines the date based on the position of the earth relative to the sun;

The lunar calendar defines the date based on the position of the moon relative to the earth; No.

The number of days per month in the Gregorian calendar is artificially adjusted to make up for the error of less than 1 day from the earth's revolution time each year;

The number of days per month of the lunar calendar is subject to the orbit period of the moon and the hidden sphere around the earth, with an error of less than 1 day, 30 days for the big month and 29 days for the small month, and the average is close to the cycle of the moon around the earth through the combination of size, in order to ensure the relative stability of the season, the annual time needs to be the same as the time of the earth's revolution around the sun, and the number of days in a year is increased by appropriately increasing the leap month to ensure that the average is close to the cycle of the earth around the sun.
