By comparing the parallel columns, the reader can determine which events were contemporaneous, or how many years separated two different events.To place all the events on the same time scale, Eusebius used an Anno Mundi (A.

It is also "the determination of the actual temporal sequence of past events".
Chronology is the science of locating historical events in time.
(AD 1 = AUC 754.) Dionysius Exiguus’ Anno Domini era (which contains only calendar years AD) was extended by Bede to the complete Christian era (which contains, in addition all calendar years BC, but no year zero).
Ten centuries after Bede, the French astronomers Philippe de la Hire (in the year 1702) and Jacques Cassini (in the year 1740), purely to simplify certain calculations, put the Julian Dating System (proposed in the year 1583 by Joseph Scaliger) and with it an astronomical era into use, which contains a leap year zero, which precedes the year 1 (AD).
The study of the means of placing pottery and other cultural artifacts into some kind of order proceeds in two phases, classification and typology: Classification creates categories for the purposes of description, and typology seeks to identify and analyse changes that allow artifacts to be placed into sequences.
Laboratory techniques developed particularly after mid-20th century helped constantly revise and refine the chronologies developed for specific cultural areas.Modern historians use it much more frequently than the Romans themselves did; the dominant method of identifying Roman years was to name the two consuls who held office that year.Before the advent of the modern critical edition of historical Roman works, AUC was indiscriminately added to them by earlier editors, making it appear more widely used than it actually was.By synchronizing an event it becomes possible to relate it to the current time and to compare the event to other events.Among historians, a typical need to is to synchronize the reigns of kings and leaders in order to relate the history of one country or region to that of another. D.) is one of the major works of historical synchronism. The first contains narrative chronicles of nine different kingdoms: Chaldean, Assyrian, Median, Lydian, Persian, Hebrew, Greek, Peloponnesian, Asian, and Roman.Much of modern historical datings and chronology of the ancient world ultimately derives from these two works.
