What are the ways historians label time?

Historians label time using various frameworks, primarily categorized into eras, periods, and epochs. These designations often reflect significant events, cultural shifts, or technological advancements, such as the Middle Ages or the Industrial Revolution. Historians may also use chronological dating systems, like BCE (Before Common Era) and CE (Common Era), to provide a standardized timeline for historical analysis. Additionally, thematic labels, such as the Enlightenment or the Cold War, help contextualize specific developments within broader historical narratives.
