What does chronology mean?
Chronology is the discipline — and the practical art — of placing events in their correct order in time and assigning them dates. As a field of study, it underpins history and archaeology: scholars use documents, inscriptions, tree rings, and radiocarbon dating to build accurate chronologies of the past. In everyday use, a chronology is simply a timeline, a list or narrative that presents events as they happened, from earliest to latest. The word carries connotations of orderliness and rigor; to say a report lacks clear chronology implies confusion about what happened when. Derived from the Greek words for time (chronos) and study (logos), chronology has been central to Western scholarship since antiquity. It remains indispensable wherever causation matters, because understanding which event came first is often the key to explaining why anything happened at all.
The study or science of arranging past events in their order of occurrence in time.
"Her expertise is in the chronology of ancient Egypt."
In this sense, chronology refers to the scholarly discipline.
An ordered list or account of events together with their dates.
"The book opens with a helpful chronology of the major battles."
Often used with 'a' or 'the' when referring to a specific timeline.
The plural is used when referring to multiple distinct timelines or dating systems, such as those of different cultures.
"The volume compares the chronologies of Mesopotamian and Egyptian civilizations."
Chronology literally means 'the study of time' — the ancient Greeks took timekeeping so seriously they made it a science of its own, alongside geometry and astronomy.

Etymology of chronology
Chronology comes from the Greek 'chronos' (time) combined with '-logia' (study or discourse), so it literally means 'the study of time'. It entered English in the early 17th century through Latin writings on historical dating. The same Greek root gives us related terms such as chronometer, chronicle, and synchronize, all concerned with measuring, recording, or coordinating time.
