The comparison of different calendars illustrates the interpretation of the calendar and what is the

To understand the calendar, we must first know the three cycles, which are the cycle of the moon revolving around the earth, the cycle of the earth revolving around the sun, and the calendar cycle. The lunar calendar that coordinates the cycle of the moon's rotation around the earth and the calendar cycle; The solar calendar that coordinates the rotation cycle of the earth around the sun and the calendar cycle; The harmony of the three cycles at the same time is called the lunisolar calendar. The Gregorian calendar refers to the Western calendar, which is a kind of solar calendar, so it is sometimes called the solar calendar; The lunar calendar is a lunisolar calendar used in our country in the past, but it is sometimes mistakenly called a lunar calendar.

The lunar calendar has been used since the Xia Dynasty, and it is the only one that has survived among many calendars in our country in the past. Oh.

The common method of the calendar is the Gregorian calendar.

The Gregorian calendar is now the internationally used calendar, also known as the Gregorian calendar, and in China it is also called the Western calendar, or the new calendar. It was promulgated in 1582 by Pope Gregory XIII after revising the original Julian calendar. He revised the Julian calendar that had been used before, dividing each year into 12 months, with the beginning of the year as January 1, the month as the first, middle, and last month, and each decade into ten days, and each day into 24 hours, 60 minutes per hour, and 60 seconds per nano minute.

February in leap years has 29 days, while February in non-leap years has only 28 days. Every 4 years in the Gregorian calendar, there are 29 days in February in leap years and only 28 days in February in ordinary years.

The Gregorian calendar is related to the movement of the earth around the sun and is a type of solar calendar.

No, the differences are as follows:1. The time is different.

The lunar calendar is the twelve months of a common 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.

2. The number of days is different.

The length of the calendar month is determined by celestial phenomena, with the 30th day for the big month and the 29th day for the minor month. 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.

3. The name is different.

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

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

Ten. V.XVI; The end of the month is September 30, and the word "day" is not added after the salutation.

The Gregorian calendar is also known as the Gregorian calendar, and the name of the orange is often called a certain day of a certain month, such as: March 12, April 20, May 31, the time must follow the word "day".

The explanation of the words of the calendar is: the method of calculating time by year, month, and day. It is mainly divided into three categories: the solar calendar, the lunar calendar, and the lunisolar calendar. The specific calendar also includes the method of the year.

Due to the rotation of the earth, the phenomenon of day and night alternated between day and night, and the concept of "day" was born. The time it takes for the earth to rotate around is called a day, also called a day. If you use days to calculate longer time intervals, then large numbers will appear, so it is necessary to establish units for measuring longer time intervals.

Since ancient times, people have chosen a time measurement system based on the return year, and determined the relationship between the unit of the return year and the day, and how to choose the starting point. We call this method the calendar. The year of return is also called the year of the sun.

The cycle in which the earth revolves around the sun to produce a cycle of four seasons is the return year. A return year is the day. However, in the calendar, a year must contain an integer of days, known as a calendar year.

With the development of human society, great efforts have been made to make the average length of the calendar year as close as possible to the length of the return year. As a result, the calendar has undergone many changes. There are three main types of calendars: the solar calendar, the lunar calendar, and the lunisolar calendar.

The solar calendar, or Gregorian calendar, is now commonly used. The normal year of the solar calendar is defined as 365 days. The year is divided into 12 months:

It is a big month, with 31 days per month and a small month, 28 days in February, and 30 days per month for the rest of the month. In this way, the time of each year of the solar calendar is shorter than that of a return year, and the time of every four years is shorter, i.e., every year divisible by 4 is a leap year, and February of a leap year is given an additional day to 29 days. However, there are 365 4 1 = 1461 days in the four years of the solar calendar, and there are about 3 days more days in the four years of the return year, that is, the four years of the solar calendar are about three days longer than the four years of the return year, so the four hundred years of the solar calendar will be about 3 days longer than the four hundred years of the return year.

In other words, in addition to placing a leap year every four years, the Gregorian calendar also has to subtract 3 days every 400 years to make its average year length closer to the length of the return year. For this reason, it is stipulated internationally that in every 400 years, only the years in which the century years (such as 1900, 2100, and 2200 are called century years) are divisible by 4, that is, every hundred years are divisible by 400 are considered leap years, for example, 2100, 2200, and 2300 are all century years, but they are not leap years; The years 2000, 2400, and 2800 are both century and leap years. The average annual length of the Gregorian calendar is (365 400 100 3) 400 = days.

In this way, it is only a day away from the year of return, and it will take more than 3,000 years for the difference between the two to be one day. Obviously, its accuracy is already very high. As a result, the Gregorian calendar (i.e., the current Gregorian calendar) has been widely adopted by countries around the world.

The Gregorian calendar was adopted in 1912.
