The term “Common Era” can be found in English as early as ,  and became more widely used in the midth century by Jewish religious scholars. In the later 20th century, the use of CE and BCE was popularized in academic and scientific publications as a culturally neutral term.

This figure is directly based on the proportion of radiocarbon found in the sample. It is calculated on the assumption that the atmospheric radiocarbon concentration has always been the same as it was in and that the half-life of radiocarbon is years. To give an example if a sample is found to have a radiocarbon concentration exactly half of that for material which was modern in the radiocarbon measurement would be reported as BP.
In order to see what a radiocarbon determination means in terms of a true age we need to know how the atmospheric concentration has changed with time. Many types of tree reliably lay down one tree ring every year. The wood in these rings once laid down remains unchanged during the life of the tree. This is very useful as a record of the radiocarbon concentration in the past.
If we have a tree that is years old we can measure the radiocarbon in the rings and see what radiocarbon concentration corresponds to each calendar year. Using very old trees such as the Bristlecone Pines in the western U. To extend this method further we must use the fact that tree ring widths vary from year to year with changing weather patterns. By using these widths, it is possible to compare the tree rings in a dead tree to those in a tree that is still growing in the same region.

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a shorter history than BC and AD, although they still date from at least the early s. Since the Gregorian calendar has superseded other calendars to become the international standard, members of non-Christian groups may object to the explicitly Christian origins of BC and AD.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.
