A diamond jubilee celebrates the 60th anniversary of a significant event related to a person (e.g. accession to the throne, wedding, etc.) or the 60th anniversary of an institution's founding. The term is also used for 75th anniversaries, although the human lifespan makes this usage more common for institutions.
The Diamond Jubilee of Queen Victoria celebrated her 60-year reign on 22 June 1897. The Diamond Jubilee of Queen Elizabeth II was celebrated across the Commonwealth of Nations throughout 2012. George III of the United Kingdom died a few months before his diamond jubilee was due in 1820.
In East Asia, the diamond jubilee coincides with the traditional 60-year sexagenary cycle, which is held in special importance despite not generally being called a "diamond jubilee."
The longest reigning monarch in history, Sobhuza II of Swaziland, celebrated his diamond jubilee in 1981, dating from when he gained direct rule.
