origin

The current Gregorian calendar is also translated into China calendar, Russian calendar, Gregorian calendar and Gregorian calendar, which is called Gregorian calendar. Julian calendar was reformed by Italian doctor and philosopher aloysius Lilius and promulgated by Pope Gregory XIII in 1582. "A.D." came into being in the 6th century.

At that time, in order to expand the ruling power of the church, believers attached almost everything to Christianity. In 525 AD, a believer named De Onisi put forward the view that Jesus was born 284 years before Diocletian's date in ancient Rome in order to predict the date seven years later (AD 532), and advocated the method of taking Jesus' birth date as the starting point, which was strongly supported by the church.

In 532 AD, the church took 284 BC as the first year of AD and used this chronology in the church. Gregorian calendar is a kind of solar calendar, which was officially adopted in China in 19 12, replacing the traditional calendar in China (namely, the constitutional calendar), while the traditional calendar in China is a kind of solar calendar, and the western calendar is also called solar calendar, western calendar and new calendar in Chinese.
