Why should the current Gregorian calendar be used all the time?

The current Gregorian calendar is oneGregorian calendar,Solar calendar.

Also known as the solar calendar, it is based on the earth's revolution around the sun.

The calendar is based on the cycle of movement.

The calendar year of the solar calendar is approximately equal to the return year, which is 12 months of the year, and this "month" is actually the same as the synodic month.

Independent. The months and days of the solar calendar are in good agreement with the position of the sun on the ecliptic, and according to the dates of the solar calendar, the changes of the four seasons can be clearly seen in the year; But in each month, the moon's new signs, hopes, and strings are not visible.

The Gregorian calendar that is now used in the world is a kind of solar calendar, with 365 days in a normal year, 366 days in a leap year, a leap every four years, a less leap once every 100 years, and a leap again in the 400th year, that is, there are 97 leap years in every 400 years. The average length of the calendar year in the Gregorian calendar is only 26 seconds away from the return year, and it is only one day to accumulate 3,300 years.

There are 365 days in a normal year and 366 days in a leap year, one leap every four years, one less leap every 100 years, and another leap in the 400th year, that is, 97 leap years every 400 years. The average length of the calendar year in the Gregorian calendar is only 26 seconds away from the return year, and it is only one day to accumulate 3,300 years.

It is called the Gregorian calendar, and it was invented by the scholar Julius.

The calendar is a method of calculating time according to celestial phenomena to meet the needs of people's daily life. The calendar based on the Moon's orbit around the Earth is called the lunar calendar; The calendar, which is based on the position of the sun in different seasons, is called the solar calendar. There are two kinds of names for the calendar that are common in our country:

Gregorian calendar, lunar calendar (leap years have 13 months, because the moon has to circle the earth 13 times a year to complete a year).

In terms of classification criteria, the lunar calendar corresponds to the solar calendar, plus the lunisolar calendar, there are only these three calendars. No calendar in the world can break out of the classification of these three calendars. The "Gregorian calendar" (new calendar) that is common in the world is actually a solar calendar, while the "lunar calendar" (old calendar) of the traditional Chinese calendar belongs to the lunisolar calendar.

The Chinese calendar, the Hindu calendar, and the Jewish calendar are lunisolar calendars with 12 or 13 months in a year; The Islamic calendar is a lunar calendar with only 12 months in a year. After the Xinhai Revolution, China began to adopt the Western Gregorian calendar, commonly known as the "new calendar", as opposed to the old Chinese calendar.

The so-called calendar, simply put, is the law of measuring long time intervals according to the natural law of celestial changes, judging climate changes, and predicting the coming of seasons. The history of ancient Chinese astronomy is, in a certain sense, a history of calendar reform.

The river of time is infinite, and only by determining the exact location of each day in it can we record history and organize life. The calendar we use every day has extremely detailed regulations on the "date" of each day, which is actually the most intuitive expression of the calendar in life.

The year, month, and day are the three major elements of the calendar. The year, month, and day in the calendar should theoretically be approximately equal to the natural units of time—the return year, the synodic month, and the true solar day, which are called calendar days, calendar months, and calendar years. Neither the synodic month nor the return year is an integer multiple of the day, nor is a return year an integer multiple of the synodic month.

But if we divide a complete day into two consecutive months or two consecutive years, we will feel awkward, so the year and month in the calendar must contain whole "days".

It is the result of the long-term accumulation of the Chinese nation based on agricultural activities, and it was not invented by one person.

The lunar calendar is a traditional calendar adopted by China for a long time, which determines the month with the cycle of synodic hope, and uses the method of intercalation to make the average length of the year close to the return year of the sun, because this calendar arranges the 24 solar terms to guide agricultural production activities, so it is called the lunar calendar, commonly known as the lunar calendar, and has the names of summer calendar, Han calendar, etc. The lunar calendar is a type of calendar currently used in China in parallel with the Gregorian calendar, and although people are accustomed to calling it a "lunar calendar", it is actually a lunisolar calendar, not a lunar calendar that formulates a calendar according to the lunar cycle.

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.

Our current Gregorian calendar is a solar calendar (also known as the solar calendar), which is based on the return year of the earth's rotation cycle around the sun, and its calendar year is approximately equal to the return year. The length of the return year is 365 days, 5 hours, 48 minutes and 46 seconds, which is the day. In order to coincide with the return year, the year is set as 365 days in the solar calendar, which is called a common year; At the same time, the year is divided into 12 months, of which seven months are big months, each month is 31 days, four months are small months, each month is 30 days, and February is 28 days.

In this way, every four years is almost one day longer than the year of the return, so this day is added to February of the fourth year, and this year is called a leap year, with a total of 366 days in the year. Thus every four years there are three common years and one leap year. According to the date of the solar calendar, the changes of the four seasons can be clearly seen in the year, for example, March 21 is the spring equinox, June 22 is the summer solstice, September 23 is the autumn equinox, and December 22 is the winter solstice; But its moon has nothing to do with the synodic month, so according to the month of the solar calendar, the moon's synod, wang, and two strings cannot be seen.

Another calendar in our country, the lunar calendar, is to use a strict synodic cycle to determine the month, and to set a leap month to make the average length of the year similar to the return year, and has the nature of both lunar months and solar years, so it is essentially a lunisolar calendar. Because it is based on the cycle of the moon's movement, and at the same time takes into account the cycle of the earth's movement around the sun, it can not only make each month basically conform to the seasonal changes, but also make the date of each month correspond to the month.

Summary. Hello, the following information ** on the network, here to help you query: the current Gregorian calendar is a kind of solar calendar, also known as the Gregorian calendar or the Western calendar, which is a calendar formulated by Pope Gregory XIII in 1582 AD, and is currently the standard calendar used by most countries in the world.

The Gregorian calendar uses 365 days, 5 hours, 48 minutes and 46 seconds as the length of a year, 365 days in a common year and 366 days in a leap year to ensure that the error with the earth's orbital period will not be too large.

and ruined. The official calendar, also known as the Gregorian calendar and the Western calendar, is a calendar based on the rotation of the earth, and its origin can be traced back to the Julian calendar during the Roman Republic. The Gregorian calendar was developed to accurately determine time and date, and is based on the average solar year (i.e., 365 days, 5 hours, 49 minutes and 46 seconds) and divides the year into 12 months, alternating between 31, 30 or 28 days in each mausoleum month (29 days in leap years). The Gregorian calendar is widely used and is one of the most commonly used calendars in the world.
