The Modern, Western, Christian system of indicating years by assigning them numbers from a single point in time and then designating them consecutively as B. Ancient Greek city-states used a completely different system based on local arrangements: each city-state identified a particular year by the name of the person who held a specified religious or political office in that particular city-state during that year. Therefore, the same year was known by a different designation in every city-state. Thucydides illustrates the complexity of Greek dating systems with his famous attempt in Book 2. Thucydides gave three different references to make the date of the first year of the war understandable by as many people as possible; that is, he hoped that any particular reader would be able to make sense of at least one of these three systems. To do so, of course, a reader would have needed a list that recorded in chronological order the names of the holders of the office being used as a standard of reference. By the fifth century B. Making correspondences between different local systems for indicating years, as Thucydides did, required research. The only non-local Greek system for indicating the dates of years was based on the celebration of the Olympic Games, which took place every four years. An individual year could then be specified as year one, two, three, or four of a certain Olympiad.

Overview of Dating. When paleoanthropologists refer to time in the past, it is done with either relative or chronometric dates. Relative dates give the time of an event with reference to another event that is not worldwide in scale. They tell us simply that one thing is older or younger than another. They do not tell us when an event happened in years before the present.

The Gregorian calendar is the global standard for the measurement of dates. Despite originating in the Western Christian tradition, its use has spread throughout the world and now transcends religious, cultural and linguistic boundaries. As most people are aware, the Gregorian calendar is based on the supposed birth date of Jesus Christ. Do they mean the same thing, and, if so, which should we use?
This article provides an overview of these competing systems. The idea to count years from the birth of Jesus Christ was first proposed in the year by Dionysius Exiguus, a Christian monk. Standardized under the Julian and Gregorian calendars, the system spread throughout Europe and the Christian world during the centuries that followed. These abbreviations have a shorter history than BC and AD, although they still date from at least the early s.
Since the Gregorian calendar has superseded other calendars to become the international standard, members of non-Christian groups may object to the explicitly Christian origins of BC and AD. It is widely accepted that the actual birth of Jesus occurred at least two years before AD 1, and so some argue that explicitly linking years to an erroneous birthdate for Jesus is arbitrary or even misleading. In , education authorities in Australia were forced to deny that such a change had been planned for national school textbooks amid a similar controversy triggered by media reports.
Passions are usually highest among those who see the adoption of a new system as an attempt to write Jesus Christ out of history. They argue that the entire Gregorian Calendar is Christian in nature anyway, so why should we attempt to obscure that fact?

The BC-AD or the Anno Domini calendar dating system came about almost as a byproduct of the historical debate over the dating of Easter.

At the time, many of the Asian Christians held the celebration on Nisan 14, while most others observed Easter on the Sunday that fell within that week since the Lord was resurrected on a Sunday.
It was further decided to observe the holiday on the Sunday after the first full moon on or after the day of the vernal or Northern Spring equinox. The council however, did not issue explicit instruction regarding the method of computation. The Alexandrian Easter tables, based upon a year cycle, became the dominate method, but several others continued to be in use such that, by the end of the fourth century, the celebrations varied each year by as much as five weeks.

The more the origins and development of dating systems have been and are studied, the more it becomes apparent that time is only what we make it. In the Western world, the year — be it or — predominantly refers to the number of years it has been since the birth of Jesus Christ.
The problem derives from our sources: the four Gospels and the Pauline Epistles.

The Gospels also tell us that Christ began his ministry in his 30th year, and that it lasted three years until the Passion.
