Major historical dates such as 1492 AD, 1776 AD or 1941 AD would still be rendered as 1492 CE, 1776 CE and 1941 CE.
The AD/BC method of identifying historical dates can be traced back to Catholic historians working in the early Middle Ages.
Prior to the 6th century AD, many Christians who didn’t use an Anno Mundi (in the year of the world) type system relied on Roman dating, either marking dates from the year legend had it that Romulus and Remus founded Rome (753 BC) or by relying on the date system established under the Roman emperor Diocletian (244-311), based on the accession of Diocletian.
However, most Christians weren’t too fond of Diocletian, since he brutally persecuted them in the latter part of his reign in the late third / early fourth century.
The great early astronomer Kepler dated that eclipse to 4 BCE.
Most historians now place Herod's death as during 4 BCE.
The change is simply one of semantics—that is, AD 100 is the same as 100 CE; all that changes is the label.
There are many religious calendars in existence, but each is normally in use in one region of the world -- typically by followers of a single religion.Converting historical dates to the standard Gregorian calendar would not have been easy.Using the birth of Jesus Christ as a central point made more sense to the religious historians.Almost all of the world's religious calendars are based on religion, astrology, or myth: The division between BC/BCE and AD/CE is not based on religious considerations.
Nothing of a religious nature happened during 1 BCE and 1 CE -- in fact nothing of truly momentous importance happened at all, to our knowledge. Selector .selector_input_interaction .selector_input. Selector .selector_input_interaction .selector_spinner.
