The categorisation 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. These can be divided broadly into prehistorical periods and historical periods (when written records began to be kept).

The number of periods and their time frames depend on the chosen topics, and the transitions between periods are often more fluid than static periodization ...
