Ways to tell them apart:

etymology
  • A "millennium" is a period of 1,000 years, while a "century" is a period of 100 years.
  • Remember "million" in "millennium" to associate it with a larger number of years compared to "century".
  • Think of the "C" in "century" as "cent" or 100, indicating a smaller time span.
  • The prefix "mille" in Latin means thousand, which helps recall that millennium is 1000 years.
  • Centuries are often numbered with Roman numerals (e.g., 20th Century for the 1900s), while millennia can be referred to by their ordinal numbers (e.g., the third millennium).
