what is chronology:
As chronology are called auxiliary discipline of history that is in charge of determining the order and dates of historical events. The word comes from the Greek χρονολογία (chronologia), which is composed of the roots χρόνος (chronos), which means ‘time’, and λόγος (logos), which translates to ‘study’ or ‘science’.
The need for the discipline of the chronology for the study of history lies in the variety of systems of dating that different civilizations and societies developed throughout history. There arises the need to establish a universal timeline that allows you to locate on a time line of events and historical events for your study and understanding.
The two most important dating systems of our civilization have been the Julian calendar, of Roman origin, and until our days, Gregorian calendar, which is Christian.
Chronology, in this sense, is based on the principle that all the facts are related to each other, therefore, by ordering them, we can better understand its evolution.
A chronology also serves as a tool to relate facts in an orderly fashion, in the order in which events were taking place: “the article must be published together with a chronology of events”.
As chronology, on the other hand, also called the successive series of people or historical events that are sorted by dates: “We are preparing a chronology of the life of James Joyce”.
Relative and absolute chronology
In archaeology, as a relative chronology is called the procedure by means of which the prior or after an object or culture in relation to another can be set. As such, it allows sorting finds in sequence. For its part, the absolute chronology is one that allows you to set the exact date of manufacture or use of an object according to a universal chronological system.
