Did you know?

A centenary, like its cousin centennial, is an anniversary. Thus, the year 2013 may mark the centenary of a town's founding, and the year-long calendar of public events that the town sponsors for the occasion—that is, the celebration of the anniversary—can also be called a centenary. Individuals have their own centenaries, which usually celebrate their births; thus, Gerald Ford's centenary will occur in 2013, and John Kennedy's in 2017. And if you live long enough to be a centenarian, you'll be around to join the celebrations.

Examples of centenary in a Sentence
