First, a definition--a century is a hundred years. That's the easy part. The slightly tricky part is to figure out which years fall in any particular century. For instance, the year 1997 is part of the twentieth century. So were the years 1941, 1911 and 1999. In other words, all of the years that begin with 19 fall into the twentieth century . . . well, almost. The exceptions are 1900, which is part of the 19th century, and 2000 which is part of the 20th century.
