Century
From Simple English Wikipedia, the free encyclopedia
A century is a way to describe a length of time. One century is one hundred years. The ancient Romans used the word century to describe a group of about one hundred soldiers, organized into a single unit.
The Roman numeral for 100 is "C".
Centuries in the Gregorian Calendar (the most-commonly used calendar, with 365 days) begin at 1. That means that in the year 2006, we are in the 21st, rather than 20th, century.
