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.In spite of these deficiencies, the dating system devised by Exiguus is now too deeply ensconced in the Western world to easily change.The only drawback of this method is that it is difficult to ascertain the uncertainty in the date found in this way.An extension of this technique uses a Monte-Carlo simulation to sample possible C concentrations consistent with the measurement made and for each of these possibilities performs a Chi-squared fit.Many different techniques can be used to measure bone fluoride content, but measurement by ion selective electrode is the easiest and simplest method available today.Fluorine dating is a method that measures the amount of fluoride absorbed by bones in order to determine their relative age.In the May 1999 issue of dating as far back as 1819, the authors of the May 1999 article showed that the compilers of the Almanac used the term to label the third Full Moon in a season which has four. This gives the calendar date where the data fit best and allows tests of how good the fit is.

In that article, Hiscock traced the many meanings of the expression over the centuries, but noted that the "two Full moons in a single month" meaning couldn't be explained satisfactorily.This can then be used to calculate a range of most likely dates in a similar way to the probability method of C calibration.The theories underlying all three methods are discussed in this paper and a comparison made for the fitting of specific model sequences.This method yields a distribution of values in the calendrical time-scale, from which the overall dating uncertainty can be derived.A third, rather different approach, based on Bayesian statistics, calculates the relative likelihood of each possible calendar year fit.Fluoride ions are present in trace amounts in most soils and groundwaters.
