The Centenary of Rotary International was held in the 2004-2005 Rotary year.  Rotary was founded on 23 February 1905.
The Centennial Governors were charges with Celebrating Rotary and this was done by encouraging and supporting all clubs to create a lasting Centennial project in their community, something over 80% of clubs did.  In addition, there were District special celebration events cumulating in the massive Rotary Convention in Chicago.  A Centennial book was produced: A Century of Service – the story of Rotary International
The Rotary Foundation celebrated its centennial in the 2016-2017 Rotary year.  The Rotary Foundation was formed in 2017 with the first donation then and the Foundation was (re)named The Rotary Foundation in 1928. Throughout the year the global and local contribution of The Rotary Foundation was celebrated in District and international events.  A Centennial book was produced: The Rotary Foundation - Doing Good in the World
