Centuries

A century is a period of 100 years. It’s a way to measure long chunks of time, often used in history to group events and developments. For example, the 20th century covers the years 1901 to 2000, while the 21st century began in 2001 and will end in 2100. Centuries are helpful for organizing historical timelines, understanding progress, and seeing how society and technology evolve over time. They serve as convenient reference points to make sense of the vast span of human history.
