A diamond jubilee celebrates the 60th anniversary of a significant event related to a person (e.g. accession to the throne or wedding, among others)[1] or the 60th anniversary of an institution's founding. The term is also used for 75th anniversaries,[2][3][4] although the human lifespan makes this usage more common for institutions.[5]
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." Monarchs such as the Kangxi and Qianlongemperors of China and Emperor Hirohito of Japan held celebrations for their 60th year of reign, as did King Bhumibol Adulyadej of Thailand on 10 June 2006.
National governments also mark their 60th anniversary as diamond jubilees, as did the Republic of Korea in 2005 and the People's Republic of China in 2009. In South Asia, the term is also used for certain 100-day anniversaries. In the Indian and Pakistani film industries, a "diamond jubilee" film is a title that has been featured in cinemas for 100 days, and beyond.
