Milenii

Milenii is the Romanian term for millennia, i.e., periods of one thousand years. In historiography and archaeology, a millennia refers to any consecutive thousand-year interval. The system commonly uses BCE (Before Common Era) and CE (Common Era) to designate years within millennia. For example, the first millennium BCE spans from 1000 BCE to 1 BCE, the first millennium CE from 1 CE to 1000 CE, the second from 1001 CE to 2000 CE, and the third from 2001 CE to 3000 CE. Millennia are often used for broad overviews of long-term trends in population, technology, or cultural change, whereas centuries are used for more detailed analysis.

Etymology: The term originates from Latin mille annus, meaning thousand years, and was transmitted to Romance languages through forms such as French millénaire and English millennium. In Romanian, mileniu is the form used for "millennium," with milenii as its plural.

Notes: While widely understood, the precise boundaries of a millennium can vary in some historical treatments, particularly for BCE dates where inclusive versus exclusive counting can lead to differences.
