The western-style year dating convention commonly used in many parts of the world was created by the monk Dionysius Exiguus in or about the year AD 532.
The convention is based on Exiguus' determination of the year in which Jesus Christ was born.
E., when a Christian monk called Dionysius Exiguus wanted to record and predict religious holidays such as Easter. One argument is an appeal to plain honesty — that since everyone knows what the epoch is really about, it is a hollow token gesture, serving no purpose beyond political correctness, to alter the labels.
But Exiguus did not like that, since Diocletian launched one of the greatest persecutions of Christians in history. Therefore, since the BCE/CE is technically an arbitrary date, which is set due to the historical precedent of BC/AD in the Gregorian calendar, and doesn't shift, it will always remain accurate.
Another proposal, by Cesare Emiliani, is the Holocene Era, with an epoch of 10,000 BCE.
This has the advantage that the arithmetic for conversion is far more straightforward than Julian Era: 2013 CE = 12013 HE and the simple fact it is based on actual science, and not solely on an arbitrary date to appease Christians while still not "being Christian".
("Ante Vero Incarnationis Dominicae Tempus" or "the Time Before the Lord's True Incarnation"). There are several arguments against the usage of the Common Era system, usually by Fundamentalist Christians.
While this style of dating is actually quite old, having originated in the seventeenth century, only recently have scholars and historians recognized the privileging of Christianity in the AD/BC method, and re-adopted the more neutral Common Era designations. In Exiguus' time, the dominant system was Anno Diocletiani - years since the beginning of the reign of the Emperor Diocletian. The birthdate of Jesus was definitely not in 1 AD,, and definitely not around December 25th.For instance, in the date AD 2001, the prefix "AD" stands for "Anno Domini" which is Latin for "the year of our Lord." Similarly, in the date 500 BC, the suffix "BC" stands for "Before Christ." In sixth century Europe, the concept of "zero" was still unknown. Furthermore, modern scholars believe Christ's birth was actually four years earlier than Exiguus thought.The names of the days of the week and several of the months of year (in English and other Indo-European languages) also have religious origins in the deities of antiquity.Yet there has been no substantial movement to rename these more secularly, other than a short-lived renaming within Turkmenistan in the early 21st century, under the dictator Saparmurat Niyazov.
As Christianity became increasingly dominant, it eventually began to encompass almost the whole of the literate community in Europe, with religious communities becoming the main bastions of histories during the Middle Ages. for the most part, with various local varieties of B. Another criticism of the Common Era system is that it leaves much of history in BCE dates, and for added confusion lacks a year zero.
It is no surprise, then, that they began to use the same method of dating for both their religious timekeeping and secular events. There have been several suggestions to pick an earlier starting point, which would enable a single system to address all of history.
