65th Wedding Anniversary
In Britain and other Commonwealth countries, the reigning monarch will send a message to the happy couple upon celebrating their 60th, 65th, and 70th wedding anniversaries, providing an application is put in to Buckingham Palace.
For subsequent anniversaries, a greeting card is sent.
Australians may receive a congratulatory letter from the 50th anniversary and onwards.
Similar salutations may occur in Canada and the United States.
