In South Asian usage, a "platinum jubilee" refers not to an anniversary, but the celebration of 75 weeks. For instance, in Pakistan and India, a platinum jubilee film is one shown in cinemas for 75 weeks or more. The success measure for a 'super hit film' is minimum six months release on its main cinema.
The next level of celebration, an anniversary of 75 years, is called a Diamond Jubilee. An anniversary of 100 years is simply called a centenary.
