The 25th (silver) or 30th anniversaries are often marked within the immediate family, since they often coincide with the end of the child-rearing phase of family life.
Broader groups in society, especially the extended families (including any grandchildren), may help to celebrate later events, such as the 40th, 50th, and 60th anniversaries.
