Centennial
From Wikipedia, the free encyclopedia
For other uses, see Centennial (disambiguation).
A centennial or a centenary is a 100-year anniversary.
Governments often declare a Centennial Day in honor of such anniversaries. Some monarchies, including the Low Countries, allow organisations that have celebrated their centennial anniversary to adopt (or petition for) the entirely honorary predicate 'Royal' (or its equivalent, e.g. koninklijk in Dutch).
