On a wedding anniversary, couples may choose to renew their
marriage vows, which is often done through a
church service offered in various
Christian denominations (such as the
Evangelical-Lutheran Churches or the
Catholic Church). In English-speaking countries, the tradition of associating gift-giving with wedding anniversaries became more prevalent in the nineteenth century. Additionally, the gifts associated with each anniversary expanded. Paper was recommended for the first anniversary, wood for the fifth anniversary and tin for the tenth anniversary. In the twentieth century, increased commercialization led to the inclusion of more anniversaries to a list of predetermined gifts. By the early 1900s, gifts of straw for the second anniversary, candy for the third, leather for the fourth, flowers for the seventh, linen for the 12th, crystal for the 15th and china for the 20th were suggested. Today, lists cover every year up to the 50th anniversary and beyond. In some parts of the world, couples can receive special recognition from government officials for particular milestones. In the
Commonwealth realms, a couple can receive a message from the monarch for 60th, 65th and 70th wedding anniversaries and for any wedding anniversary thereafter. This is done by applying to
Buckingham Palace in the
United Kingdom or to the
governor-general's office in the other Commonwealth realms. In
Australia, couples can receive a congratulatory letter from the governor-general on the 50th and all subsequent wedding anniversaries. The prime minister, the Leader of the Opposition, local members of both state and federal parliaments as well as state governors may also send salutations for the same anniversaries. In Canada, couples can also receive a message from the governor-general for the 50th anniversary and every fifth anniversary after that. In the
United States, a couple can receive an anniversary greeting card from the president for the 50th and all subsequent anniversaries.
Catholics may apply for a
papal blessing through their local diocese for wedding anniversaries of a special nature (25th, 50th, 60th, etc.). ==Commercial gifts==
