A  wedding  Anniversary  is  the  anniversary of  the  date  a  wedding  took  place.  Traditional  names  exist  for  some  of  them:  for  instance,  50 years  of  marriage  is called a "golden wedding anniversary"  or simply a "golden anniversary"  or  "golden wedding".

The  names  of  some  anniversarie s provide guidance  for  appropriate  or  traditional  gifts for  the  spouses  to  give  each  other;  if  there  is a  party  these  can  be  brought  by  the  guests  or  influence  the  theme  or  decoration.
