List of time periods

The categorization of the past into discrete, quantified named blocks of time is called periodization.^[1] This is a list of such named time periods as defined in various fields of study. Major categorization systems include cosmological (time periods in the origin and mass evolution of the universe), geological (time periods in the origin and evolution of the Earth), anthropological and historical (time periods in the origin and evolution of human civilization).

Human time periods

These can be divided broadly into prehistorical (before history began to be recorded) and historical periods (when written records began to be kept).

In archaeology and anthropology, prehistory is subdivided around the three-age system, this list includes the use of the three-age system as well as a number of various designation used in reference to sub-ages within the traditional three.

The dates for each age can vary by region. On the geologic time scale, the Holocene epoch starts at the end of the last glacial period of the current ice age (c. 10,000 BCE) and continues to the present. The beginning of the Mesolithic is usually considered to correspond to the beginning of the Holocene epoch.

General periods

• Pre-History – Period between the appearance of Homo ("humans"; first stone tools c. three million years ago) and the invention of writing systems (for the Ancient Near East: c. five thousand years ago).
  • Stone Age
    • Paleolithic – is the earliest period of the Stone Age
      • Lower Paleolithic — time of archaic human species, predates Homo sapiens
      • Middle Paleolithic — coexistence of archaic and anatomically modern human species
      • Upper Paleolithic — worldwide expansion of anatomically modern humans, the disappearance of archaic humans by extinction or admixture with modern humans; earliest evidence for pictorial art.
    • Mesolithic (Epipaleolithic) – was a period in the development of human technology between the Palaeolithic and Neolithic periods.
    • Neolithic – a period of primitive technological and social development, beginning about 10,200 BCE in parts of the Middle East, and later in other parts of the world.
    • Chalcolithic (or "Eneolithic", "Copper Age") – this period was still largely Neolithic in and civilizations who had adopted or developed a writing system.
  • Protohistory – Period between prehistory and history, during which a culture or civilization has not yet developed writing but other cultures have already noted its existence in their own writings; the absolute time scale of "protohistory" varies widely depending on the region, from the late 4th millennium BCE in the Ancient Near East to the present in the case of uncontacted peoples.
• Ancient History – Aggregate of past events from the beginning of recorded human history and extending as far as the Early Middle Ages or the Postclassical Era. The span of recorded history is roughly less than five thousand years, beginning with the earliest linguistic records in the third millennium BCE in Mesopotamia and Egypt.
  • Classical Antiquity – Broad term for a long period of cultural history centered on the Mediterranean Sea, comprising the interlocking civilizations of ancient Greece and ancient Rome, collectively known as the Greco-Roman world. It is the period in which Greek and Roman society flourished and wielded great influence throughout Europe, North Africa and the Middle East.
• Post-Classical History – Period of time that immediately followed ancient history. Depending on the continent, the era generally falls between the years CE 200–600 and CE 1200–1500. The major classical civilizations the era follows are Han China (ending in 220), the Western Roman Empire (in 476), the Gupta Empire (in the 550s), and the Sasanian Empire (in 651).
  • Middle Ages – Lasted from the 5th to the 15th century. It began with the collapse of the Western Roman Empire in 476 and is variously demarcated by historians as ending with the Fall of Constantinople in 1453, merging into the Renaissance and the Age of Discovery.
    • Early Middle Ages (also called Dark Ages)
    • High Middle Ages
    • Late Middle Ages
• Modern History – After the post-classical era
  • Early Modern Period – The chronological limits of this period are open to debate. It emerges from the Late Middle Ages (c. 1500), demarcated by historians as beginning with the Fall of Constantinople in 1453, in forms such as the Italian Renaissance in the West, the Ming Dynasty in the East, and the rise of the Aztec in the New World. The period ends with the beginning of the Age of Revolutions.
  • Late Modern Period – Began approximately in the mid-18th century; notable historical milestones included the French Revolution, the American Revolution, the Industrial Revolution and the Great Divergence
  • Contemporary History – History within living memory. It shifts forward with the generations, and today is the span of historic events from approximately 1945 that are immediately relevant to the present time. For example, the Post-Modern movement (the Soviet Union and the United States, 1973–present)

Geologic time periods

The geologic time scale covers the extent of the existence of Earth, from about 4600 million years ago to the present day. It is marked by Global Boundary Stratotype Sections and Points. Geologic time units are (in order of descending specificity) eons, eras, periods, epochs, and ages; and the corresponding chronostratigraphic units, which measure "rock-time", are eonothems, erathems, systems, series, and stages.

The second and third timelines are each subsection of their preceding timeline as indicated by asterisks. The Cenozoic is sometimes divided into the Quaternary and Tertiary periods, although the latter is no longer used officially.
