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.
History. The marking of 26 January is an important date in Australia’s history and has changed over time: starting as a celebration for emancipated convicts and.
Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place. Even when the only science we had to go on was religious literature and the western world believed the world was created in BC 1 , scholars tried to figure out when each biblical event took place, to define a chronology from savagery to civilization, from creation to the first animal, then to the emergence of the first people.
The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences. As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past. All dating methods today can be grouped into one of two categories: absolute dating , and relative dating.
The former gives a numeric age for example, this artefact is years old ; the latter provides a date based on relationships to other elements for example, this geological layer formed before this other one. Both methods are vital to piecing together events of the past from the recent back to a time before humans and even before complex life and sometimes, researchers will combine both methods to come up with a date.
Some of the methods covered here are tried and tested, representing early methods of examining past geological, geographical, anthropological and archaeological processes. Most are multidisciplinary, but some are limited, due to their nature, to a single discipline. No system is completely failsafe and no method completely correct, but with the right application, they can and have aided researchers piece together the past and solve some of their discipline’s most complex problems.
Any scientific discipline for which chronology is important may utilize these dating methods. They may tell us many things including age, but also its place in a sequence of processes.

Dating , in geology , determining a chronology or calendar of events in the history of Earth , using to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments. To date past events, processes, formations, and fossil organisms, geologists employ a variety of techniques. These include some that establish a relative chronology in which occurrences can be placed in the correct sequence relative to one another or to some known succession of events.
Radiometric dating and certain other approaches are used to provide absolute chronologies in terms of years before the present. The two approaches are often complementary, as when a sequence of occurrences in one context can be correlated with an absolute chronlogy elsewhere. Local relationships on a single outcrop or archaeological site can often be interpreted to deduce the sequence in which the materials were assembled.
In recent years, some historical scholars have advocated the use of the religiously neutral abbreviations BCE (for “Before Common Era”) to.
All of us tend to use the most significant dates in our lives as reference points for all the others. For example, we think of our age in reference to the year we were born, and while we may give names to wedding anniversaries silver, gold, etc. Just as important years are widely used reference points in the lives of individuals, so they are for entire cultures. And they often vary from culture to culture.
Although it is today in the United States, such a number might indicate a far different year in other cultures throughout history. The next question might be, what qualifies as a year significant enough to base an entire dating system upon it? The birth of Christ is the prime example. Unfortunately, it was difficult in the sixth century AD for the originator of that system, Dionysius Exiguus, to determine the exact year when Christ was born.
As a result, his determination of the birth year of Christ was apparently off by about 4 years, but the error was not realized until centuries after the system had come into general use, leading to the strange circumstance that Christ was actually born in approximately 4 BC. The ancient Romans had no one person so significant to their culture that they wanted to number their years in relation to his or her life.
Instead, they viewed Rome itself almost as a living being, the foundation of their existence as a people. Thus, it is no surprise that they based all dates on the founding of the city itself, traditionally in the year that equates to BC, and they used the abbreviation AUC Latin, ab urbe conditum to indicate it. For them, there was no precise history before the founding of their beloved city, and thus no need for a second abbreviation to cover pre-AUC years.
By the century of Dionysius Exiguus, the focus of Roman culture had shifted from a city to a Savior, and their dating system followed suit.
Types of Chronological Information
Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.
Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample.
For those researchers working in the field of human history, the chronology of Archaeologists have access to various techniques for dating.

How dating has changed over the last 100 years
By the time he reformed the Julian calendar in using the observations of Christopher Clavius and Johannes Kepler , it had drifted 10 days off course. To this day, most of the world uses his Gregorian calendar. Ironically, by the time the Catholic church buckled under the weight of the scientific reasoning that pointed out the error, it had lost much of its power to implement the fix.
The “new” calendar, as we know it today, was not adopted uniformly across Europe until well into the 18th century.
Using relative and radiometric dating methods, geologists are able to answer However, by itself a fossil has little meaning unless it is placed within some context. scientists piece together the evolutionary history of a group of organisms.
Christmas is celebrated to remember the birth of Jesus Christ , who Christians believe is the Son of God. The name ‘Christmas’ comes from the Mass of Christ or Jesus. A Mass service which is sometimes called Communion or Eucharist is where Christians remember that Jesus died for us and then came back to life. The ‘Christ-Mass’ service was the only one that was allowed to take place after sunset and before sunrise the next day , so people had it at Midnight!
So we get the name Christ-Mass, shortened to Christmas. Christmas is now celebrated by people around the world , whether they are Christians or not. It’s a time when family and friends come together and remember the good things they have. People, and especially children, also like Christmas as it’s a time when you give and receive presents! No one knows the real birthday of Jesus!
BP: How Do Archaeologists Count Backward Into the Past?
Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a “dating method”. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred.

The initials BP or bp and rarely B. While BP is also used generally as an imprecise estimate of an age of an object or event, the use of it in science was made necessary by the quirks of the radiocarbon methodology. Radiocarbon dating was invented in the late ‘s, and within a few decades, it was discovered that while the dates retrieved from the method have a sound, repeatable progression, they are not a one-to-one match with calendar years. Most importantly, researchers discovered that radiocarbon dates are affected by the amount of carbon in the atmosphere, which has fluctuated greatly in the past for both natural and human-caused reasons such as the invention of iron smelting , the Industrial Revolution , and the invention of the combustion engine.
Tree rings , which keep a record of the amount of carbon in the atmosphere when they are created, are used to calibrate or fine-tune radiocarbon dates to their calendar dates. Scholars use the science of dendrochronology, which matches those annular rings to known carbon fluctuations. That methodology has been refined and improved several times over the last few years. BP was first established as a way to clarify the relationship between calendar years and radiocarbon dates.
How Does Carbon Dating Work
In almost all archaeology books and articles the authors use dates. This is the Christian era in the Gregorian calendar, starting from 1 AD as the year in which Christ was believed to have been born. The date was calculated about years after the event, so was a broad estimate. If lower case letters are used, this often means that the date is based on an uncalibrated radiocarbon date see below for date calibrations.
Battle of Hastings was in CE.
“The history is very vague, because it takes a long time” to adopt this sort of dating, Hunt says. “A.D. is very easy for people to cope with.
The October effect is a perceived market anomaly that stocks tend to decline during the month of October. The October effect is considered mainly to be a psychological expectation rather than an actual phenomenon as most statistics go against the theory. Some investors may be nervous during October because the dates of some large historical market crashes occurred during this month. The events that have given October the reputation for stock losses have happened over decades, but they include:.
Black Monday, the great crash of that occurred on October 19 and saw the Dow plummet The other black days, of course, were part of the process that led to the Great Depression—an economic disaster that stood unrivaled until the mortgage meltdown nearly took out the whole global economy with it. While statistical evidence doesn’t support the phenomenon that stocks trade lower in October, the psychological expectations of the October effect still exist.

Where is Juneteenth? Dating back to , it was on June 19 th that the Union soldiers, led by Major General Gordon Granger , landed at Galveston, Texas with news that the war had ended and that the enslaved were now free. The Emancipation Proclamation had little impact on the Texans due to the minimal number of Union troops to enforce the new Executive Order.
Later attempts to explain this two and a half year delay in the receipt of this important news have yielded several versions that have been handed down through the years.
The term Anglo-Saxon is a relatively modern one. It refers to settlers from the German regions of Angeln and Saxony, who made their way over to Britain after the.

Though there are a few frequently cited inflection points in that history—recorded instances of particular books using one system or another—the things that happened in the middle, and how and when new systems of dating were adopted, remain uncertain. Systems of dating before B. For example, the Romans generally described years based on who was consul, or by counting from the founding of the city of Rome.
So Anno Domini , the year of our Lord, is a very easy transition to make, as opposed to dating the year an emperor had reigned in Rome. One of the early writers to date this way was Dionysius Exiguus, a monk who, in A. Practical use of A.
