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.

This page has been archived and is no longer updated. Despite seeming like a relatively stable place, the Earth’s surface has changed dramatically over the past 4. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.

These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth’s surface is moving and changing. As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.

A more recent system uses B.C.E. which stands for “Before the Common Era” and C.E. for “Common Era.” This newer A brief history of the cultures of Asia.

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. The period before that is known as B. D short Anno Domini, and meaning the Year of our Lord.

The western-style year dating convention commonly used in many parts of the world was created by the monk Dionysius Exiguus in or about the year AD The convention is based on Exiguus’ determination of the year in which Jesus Christ was born. In sixth century Europe, the concept of “zero” was still unknown. Thus, the year 1 BC was followed by the year AD 1. 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. Perhaps the most unfortunately characteristic of this convention is that “BC” is a suffix used after the year while “AD” is a prefix used before the year. This is inconvenient when generating computerized lists because extra columns must be reserved for both prefixes and suffixes.

However, Exiguus’ dating system still lacks a “0” year which makes calendrical calculations awkward. The “astronomical” dating system refers to an alternative method of numbering years. It includes the year “0” and eliminates the need for any prefixes or suffixes by attributing the arithmetic sign to the date.

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.
