Dating the birth of Jesus Christ

I will not enter here into the nineteenth-century debate on the historical existence of Jesus Christ, for after 1926 historical criticism has unanimously accepted his existence, and the persistence of the idea that Jesus Christ did not exist is solely due to ignorance or anti-Christian bigotry.
In the previous post we saw that December 25 might actually have been the date of the birth of Christ, if we follow a tradition that dates back to Irenaeus. Traditionally, the main argument against that date was the unlikelihood of the shepherds being in the fields in winter, watching their flocks. However, other studies disagree with this statement.
The chronological system used today internationally is the Christian era. After the collapse and disintegration of the Western Roman Empire, the Roman era, which counted the years from the founding of Rome, remained in use for about two hundred years, but in the sixth century, the Scythian theologian Dionysius Exiguus introduced the custom of dating historical events from the birth of Christ. Dionisius calculated that Jesus must have been born around the year 754 AUC (Ab Urbe Condita, since the foundation of the town) and called this year 1 AD (Anno Domini, the year of the Lord). Later dates in the Roman era could easily be translated into the Christian era by subtracting 753 from the corresponding Roman date. As for the years before 754 AUC, in the new era they correspond to negative numbers and can be obtained by subtracting the Roman date from 754 and by adding the abbreviation BC (Before Christ). In this system, there is no year zero.
