etymology
  • A millennium consists of 1,000 years, while a century consists of 100 years.
  • Remember the prefix mill means a thousand, as in millipede (thousand legs) or milligram (thousandth of a gram).
  • Century begins with cent, which can remind you of a century being made up of 100 years, much like a cent is 1/100th of a dollar.
  • Millennium has three ns and feels longer, which can help you remember it covers more years than a century.
  • Think of the Roman numeral system where M stands for 1,000 and C stands for 100.
