CE

The established calendar dating system, which uses the Anno Domini ('AD') notation, is based on the calculations of Dionysius Exiguus for the birthyear of Jesus relative to the foundation of Rome. At the time, dates used the 'AD' system instituted by pagan and murderer Emperor Diocletian, which used the first year of his reign as year 1. (In that system, "AD" stood for Anno Diocletiani, and should not be confused with the present-day AD system) Because Dionysius Exiguus in the year 525 wanted to end the memorialization of an evil man who persecuted Christians, he invented a new numbering system based on his calculations of the birth year of Jesus Christ. However, as he miscalculated, the terms BCE/CE are more accurate than BC/AD as the last few years BC were not actually Before Christ, and hence 1 AD is not actually the first year after Jesus' birth The use of the phrase "Common Era" has existed for hundreds of years. The original use of 'CE' was to avoid the common practice of countries basing their dates on when their rulers reached power or were born, i.e. the "regal era" from the birthdate of Jesus Christ, which belonged to all men "the common era." While use of "Common Era" attempts to erase recognition for the Christian basis of the calendar, there are no similar attempts to erase non-Christian religious names from the calendar, such as the days of the week named after Norse gods, a dead religion. Numerous texts, particularly schoolbooks, have replaced "B.C./A.D." with "Common Era" symbols over the past decade. This is part on an international effort to establish common values for those of all cultures, not just Christians. While the calendar may be Christian in origin, it is no longer exclusively to Christians, and has not benn for hundreds of years. C.E. is a step towards a common calendar among all the world, not biased by religion.
