Goals This proposed work will extend laser ablation resonance ionization spectrometry LARIMS from the previously demonstrated rubidium-strontium Rb-Sr geochronology system to four other radiogenic systems, enabling in-situ, concordant age determinations to be made on extraterrestrial bodies in the solar system. Advantages include providing an independent test of concordance, while expanding the potential range of samples that can be successfully measured. Testing for concordance is important because individual isotopic dating systems can be biased by a variety of factors. These biases are frequently distinct for different radiometric systems. Objectives This proposal addresses the important NASA goal to understand the history and evolution of the solar system. The time of key events in solar system history are poorly constrained by current samples, giving impetus to future missions with sample return and in-situ landed dating measurements. An issue for in-situ radiometric measurements is the desire for testing concordance, i. We have demonstrated LARIMS by dating several samples using the Rb-Sr method and we have completed preliminary work that demonstrates the technique can be extended to Pb-Pb geochronology. The objective of this proposal is to perform measurements that enable us to assess LARIMS capabilities with other geochronology systems and to determine and overcome obstacles to developing in-situ measurements based on these systems in future missions.
Common questions about dates
In part 2, we explored the development of various calendar systems within the political and historical context of the major nations during Biblical times and the early church period. After all, dating an ancient event within its original calendar dating system would mean nothing without at least a common point of reference to our modern dating system.
We now examine the meaning of BC-AD , including how and why it come about. 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. According to Eusebius’ Church History , variances over the date of celebration were present within the very next generation after Jesus and the apostles. 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.

Another suggestion for the origin of the term “Common Era” CE is an anti-Christian attempt to conceal that Jesus is the historical basis for the primary calendar dating system. A later edition 11th defines it as the Christian Era. The first recorded use of the phrase “common era” was in 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.
Because Dionysius Exiguus in the year 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. While the use of the phrase “Common Era” has existed for hundreds of years, only recently have politically correct liberals attempted to replace all instances of ‘AD’ with ‘CE. Numerous texts, particularly schoolbooks, have replaced “B.

Chronology or putting things in the right order is very important in history. Can you imagine how confused you would be if you didn’t know that the Romans arrived in Britain before William the Conquerer or that Queen Victoria came to the throne after Queen Elizabeth I? This is why dates are so important to the study of history. The most commonly used system of dating things in history is the one which we use every day that is based on the Gregorian Calendar.
Under the Gregorian Calendar the year is divided into or in a leap year days which are then grouped into twelve months. The years are numbered according to the year in which Christ was believed to have been born.
Thucydides illustrates the complexity of Greek dating systems with his famous () that he devised his own system of time reckoning to use in his history.
History and Genealogy Reference Unit. Today, Americans are used to a calendar with a “year” based the earth’s rotation around the sun, with “months” having no relationship to the cycles of the moon and New Years Day falling on January 1. However, that system was not adopted in England and its colonies until Throughout history there have been numerous attempts to convey time in relation to the sun and moon. Even now the Chinese and Islamic calendars are based on the motion of the moon around the earth, rather than the motion of the earth in relation to the sun, and the Jewish calendar links years to the cycle of the sun and months to the cycle of the moon.
The Julian Calendar In 45 B. This calendar employed a cycle of three years of days, followed by a year of days leap year. When first implemented, the “Julian Calendar” also moved the beginning of the year from March 1 to January 1. By the ninth century, parts of southern Europe began observing first day of the new year on March 25 to coincide with Annunciation Day the church holiday nine months prior to Christmas celebrating the Angel Gabriel’s revelation to the Virgin Mary that she was to be the mother of the Messiah.
The last day of the year was March

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.

The development of European archaeology as a scholarly discipline in the nineteenth century was closely connected with the appearance of systematic methods for dating archaeological materials and these methods evolved largely in Scandinavia. Beginning with an analysis of the basic elements of archaeological dating systems, he traces the origin and subsequent development of these systems, examining in detail how they were built up and refined.

In case you wondered about the history of all the dating systems,well here you are! In this article I will explain everything there is to explain about these dating systems. As you might have guessed these dating systems are related to Christianity in one way or another. So there’s a history of calendars as well. So one might wonder how they would track time.
Is Time Historical? Time that was so long grows short, time, all goggle-eyed, wiggling her skirts, singing her torch song, giving the boys a buzz and a ride, that Nazi Mama with her beer and sauerkraut. Time, old gal of mine, will soon dim out. Linguists have noted that it is virtually impossible to talk about time without invoking motion wiggling skirts, engines, chariots, arrows and spatial content short, long. A clock face, for instance, provides both motion, the moving hand, and spatial content, the space traversed by the hand.
Even more modern conceptions of time seem to require spatial representation, however nonintuitive, as in, for example, the warping of space— time around black holes.

Romans tied events to consular years. Two men were elected every year to serve in the office of consul. Roman historians said that a certain event took place in the year that Marcus Such and Such and Publius So and So were consuls. Historians who lived in monarchies could date events to regnal years , that is, a time tied to the reign of a particular king. This battle was fought in the third year of King So and So.

A calendar era is the period of time elapsed since one epoch of a calendar and, if it exists, before the next one. In antiquity, regnal years were counted from the accession of a monarch. This makes the Chronology of the ancient Near East very difficult to reconstruct, based on disparate and scattered king lists, such as the Sumerian King List and the Babylonian Canon of Kings.

Three major dating systems are in use when referring to historical events within the Imperium – Terran , Vilani , and Imperial. Other races also have their own dating systems. Terran dates centre on a year about midway through the period of Vilani ascendance. After that date, years ascend and are suffixed AD; before that date, years descend and are suffixed BC.

My own mind is made up. I do not think that Jesus Christ ever existed. In Apr , Kepler, rejected from his first choice , accepted a position of teacher of mathematics and astronomy at a Protestant school in Graz, Austria. In , the local Catholic Duke, decided to drive out all Lutherans from Graz, during which point Kepler almost lost his job, but was saved by some Jesuit priests, who had been interested in his astronomical ideas, who begged the Duke to let him stay.
