A silver anniversary is another good time to take stock, to reflect upon and refresh priorities and directions.
This rating is the icing on our silver anniversary cake.
In 2014, the festival celebrates its twenty-fifth silver anniversary.
The 2006 festival, the silver anniversary, featured nine days of silent films all with live musical accompaniment.
Coincidentally, both organisations celebrate their silver anniversaries this year.
