What does the Gregorian calendar mean and what is the Gregorian calendar?

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 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 unrelated to the synodic month. 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.

The Gregorian calendar is the Gregorian calendar chronology, which is a method of chronology that originated in Western society. The Gregorian calendar is 365 days in a common year, of which.

January, March, May, July, August, October, and December are 31 days.

30 days in April, June, September and November, and 28 days in February. However, since the solar return year is actually a little longer than 365 days, there is a leap year.

Meaning of the Gregorian calendar.

The Gregorian calendar is the Gregorian calendar chronology, which is a method of chronology derived from Western society, also known as the Western calendar and Western Yuan. China still used the lunar calendar before the Xinhai Revolution, and after the Xinhai Revolution, China began to use the Common Era and the lunar calendar together, and this chronology has been used to this day.

The Gregorian calendar spread widely, and the international community basically used the Gregorian calendar chronology, and the concept of the Gregorian calendar slowly became popular in the 11th century. The Gregorian calendar generally has 365 days in a year divided into 12 months, where:

January, March, May, July, August, October, and December are 31 days.

30 days in April, June, September and November, and 28 days in February.

The time of the Gregorian calendar is basically the same as the time of the solar return year, except that since the sun actually orbits the sun for 365 days, 5 hours, 48 minutes and 45 seconds, there are always a few extra hours of time to record 365 days per year, so there will be 97 leap years every 400 years, and the duration of a leap year will be 366 days.

The Gregorian calendar was invented by foreigners, and it is determined by the time when the earth revolves around the sun. Our ancestors used the lunar calendar and the lunar calendar, the lunar calendar is based on the relationship between the earth and the moon to determine the virtual line, and the lunar calendar refers to the 24 solar terms, which are used to guide agricultural production.

The Gregorian calendar is a chronological calendar based on the sun.

"囧", the original meaning is "bright". Since 2008, it has become a popular emoji among the online community in Chinese, becoming one of the most frequently used words in online chats, forums and blogs, and it is given the meaning of "depressed, sad, helpless".

Nowadays, many people think that the lunar calendar is the lunar calendar, and the solar calendar is the lunar calendar, but in fact, this statement is not accurate. What is the difference between the Gregorian calendar, the lunar calendar, the lunar calendar, and the solar calendar?

The standard name of the Gregorian calendar is the Gregorian calendar, which is now the internationally accepted calendar.

To put it simply, it is the solar calendar.

The Gregorian calendar is short for the solar calendar, which is associated with the annual movement of the earth around the sun and has nothing to do with the phases of the moon. The Gregorian calendar is a Western calendar, not created by China, so it is also known as the "Western calendar" (as opposed to the Chinese calendar).

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

It is the Gregorian calendar, which is the same as the old calendar and the imperial calendar.

The Gregorian calendar, also known as the Gregorian calendar, is now an internationally accepted calendar.

The Gregorian calendar begins with the year of the birth of Jesus, also known as the Gregorian calendar. 365 days a year, divided into 12 months, 1, 3, 5, 7, 8, 10, December for the big month, 31 days per month, 4, 6, car.

September and November are small months, with 30 days per month, and February is 28 days.

Since the Earth's orbit around the Sun is actually 365 days, 5 hours, 48 minutes and 45 seconds (solar years), there are 97 leap years in every 400 years, and the leap year is added by one day at the end of the old number of February, and the whole year is 366 days. Leap years are calculated as follows: a leap year (e.g., 1960) divisible by 4 A.D., a common year (e.g., 1900) divisible by 100, and a leap year (e.g., 2000) divisible by 100 and divisible by 400.

Difference Between Lunar and Solar Calendar:

1. The number of days in a year is different.

A lunar common year is 12 months with an average of 354 or 355 days in a lunar year, and a leap year is 13 months with an average of 383 or 384 days. The solar calendar has only 12 months, 365 days in a common year and 366 days in a leap year.

2. The number of days per month is different.

The lunar month is 30 days long and the small month is 29 days. The big month of the solar calendar is 31 days, the small month is 30 days, and there is a special February, which is 28 days in a normal year and 29 days in a leap year.

3. The division of the 24 solar terms is different.

In the lunar calendar, the year is divided into 24 solar terms, while in the solar calendar there are no solar terms. This is because China is a big agricultural country, and the ancients creatively invented the 24 solar terms in order to make the calendar better guide agricultural activities.

The Gregorian calendar, also known as the Gregorian calendar, is now an internationally accepted calendar. The Gregorian calendar begins with the year of the birth of Jesus. There are 365 days in a year, divided into 12 months, 1, 3, 3, 5, 7, 8, 10, and December are the big months, and 31 days per month, and April, June, September, and November are small months, with 30 days per month, and 28 days in February.

There are many methods of chronology in various countries around the world, as well as the Ganzhi chronology, the Taoist calendar, the imperial chronology, the astronomical chronology, the historical chronology, etc. In addition, there are Buddhist years, Islamic years, Jewish years, Japanese years, Greek years, etc.

As early as in ancient times, some local conveniences in China had the "Stem Branch Chronology Method", that is, the ten heavenly stems and the twelve earthly branches were combined separately, and every 60 years was a cycle. In modern times, the "Yellow Emperor Era" has been used, and the so-called "Yellow Emperor Era" is a chronological method based on the legendary Yellow Emperor's birth year, and legend has it that the Yellow Emperor was born in 2698 BC. The "Yellow Emperor Era" was publicly proposed by Liu Shipei in 1903 in the "National **".

The era of the Yellow Emperor is calculated based on the Gregorian calendar.

Since the beginning of the A.D. era is 1 A.D., most scientists with a good understanding of the A.D. era and most astronomical institutions in the world explicitly support the claim that the 21st century began in 2001.
