A millennium is defined as a period of one thousand years based on the Latin word "mille," meaning "thousand." The term was established in historical contexts, particularly in relation to calendar systems and significant events, such as the transition from one millennium to another (e.g., from 1999 to 2000). In contrast, a million years would be referred to as a "megannum," derived from the Greek prefix "mega," meaning "great" or "large." Thus, the distinction arises from linguistic origins and established conventions rather than any inherent numerical logic.
