What year is the Gregorian calendar?

Gregorian calendar comes from Europe, also known as Gregorian calendar, AD, AD, and AD is more accurate. Westerners set the year of Christ's birth as AD.

The so-called "Gregorian calendar" used in the world now is the Gregorian calendar formulated and promulgated by Pope Gregory at the end of1the end of the 6th century1the beginning of the 7th century, which revised the extremely inaccurate "julian calendar" in western history. The biggest feature of this calendar is that it completely ignores the compound movement period of the moon cycle in the solar year, but divides the year into 12 months according to people's subjective mathematical division. Then, in order to adjust the difference between the sun's running day and the mathematical segmentation day that occurs every four years, a year is divided into 1, 3, 5, 7, 8, 10, 12 months is 3 1 day, April, June, September,/kloc-0. In particular, it is almost unreasonable for the Gregorian calendar to determine "January 1st". Even if they establish Christmas as the beginning of the year, it is still meaningless. That is to say, the western calendar that people use now, that is, the Gregorian calendar that we use now, basically has no scientific connotation of the unity of heaven and earth, but is only a subjective mathematical division. Even the seven-day-a-week and Sunday rest days used in the western calendar borrowed the astronomical theory that the seven stars are like an interval of the sun in the eastern calendar, but its connotation was changed into a Christian worship time series, which has nothing to do with the astronomical phenomena. Therefore, although the western calendar used by people now is universal, there are many unreasonable and unscientific problems, which do not meet the needs of counting in the computer age. Its mathematical function is much worse than Jiazi's dating method, which can be rotated from 65438 to 080 in China calendar. Whether such a calendar will be changed, revised and replaced in the future remains to be proved by world history itself.
